The HemoSphere Alta Advanced Monitoring Platform is the next-generation platform that provides a means to interact with and visualize hemodynamic and volumetric data on a screen. It incorporates a comprehensive view of patient hemodynamic parameters with an intuitive and easy user interface. The HemoSphere Alta Advanced Monitoring Platform is designed to provide monitoring of cardiac flow with various core technologies coupled with other technologies-based features such as Algorithms and Interactions. It integrates existing hemodynamic monitoring technologies into a unified platform.
The HemoSphere Alta Advanced Monitoring Platform's FDA 510(k) clearance letter and associated 510(k) summary (K252533) primarily focus on software modifications and the integration of previously cleared hardware components to an existing platform (K242451). The document states that no new clinical testing was performed in support of the subject 510(k). Therefore, the information provided mainly pertains to performance verification studies rather than standalone clinical performance studies involving ground truth establishment by experts for a novel algorithm.
However, based on the provided text, we can infer the acceptance criteria and study information as follows:
1. Table of Acceptance Criteria and Reported Device Performance
The document describes several verification activities without providing specific numerical acceptance criteria for each, except implicitly stating "All tests passed" or "All acceptance criteria were met."
| Acceptance Criteria Category | Reported Device Performance |
|---|---|
| Usability | Demonstrated that intended users can perform primary operating functions and critical tasks without usability issues that may lead to patient or user harm. All acceptance criteria were met for human factors validation. |
| System Verification (Non-Clinical Performance) | Met predetermined design and performance specifications. Differences in design and materials did not adversely affect safety and effectiveness. All tests passed. |
| Electrical Safety and EMC | Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-1-8, IEC 62304, IEC 62366-1, IEC 60601-2-34, IEC 60601-2-57, IEC 60601-2-49, IEC 60529-1, and IEC 80601-2-49. All tests passed. |
| Software Verification | Extensive software verification testing ensured safety for use, demonstrating substantial equivalence to predicate devices. All tests passed. |
2. Sample Size Used for the Test Set and Data Provenance
- For Usability Study: The document mentions "the intended users." It does not specify the numerical sample size of users or the provenance of the data (e.g., retrospective or prospective, country of origin).
- For Non-Clinical Performance (Bench Simulation): "Measured and derived parameters were tested using a bench simulation." No sample size in terms of patient data or data provenance is applicable here, as it's a bench test.
- For Software Verification: "Extensive software verification testing was conducted." No specific sample size of test cases or data provenance is provided.
- For Clinical Performance: "No new clinical testing was performed in support of the subject 510(k)." This indicates no patient-level test set data was used for this specific submission. The algorithms within the device (e.g., GHI, Smart Wedge, HPI, CAI, RVP, RVCO, AFM) likely had clinical performance studies for their initial clearances, but those details are not provided in this 510(k) for the HemoSphere Alta platform updates.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- As "no new clinical testing was performed" for this 510(k) submission, there is no mention of experts establishing ground truth for a new clinical test set.
- For the Usability Study, "intended users" participated, implying clinical professionals, but their specific qualifications or their role in establishing "ground truth" (beyond identifying usability issues) are not detailed.
4. Adjudication Method for the Test Set
- Since no new clinical test set data with expert adjudication is described in this submission, no adjudication method is mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- The document does not mention any MRMC comparative effectiveness study comparing human readers with and without AI assistance for this 510(k) submission.
6. Standalone Performance (Algorithm Only Without Human-in-the-Loop)
- While the device contains various algorithms (e.g., GHI, HPI, Smart Wedge, CAI, RVP, RVCO, AFM), this 510(k) primarily addresses software updates and hardware integration to an existing platform. It doesn't detail standalone performance studies for these specific algorithms within this document. The description of these algorithms (e.g., "additional information regarding the patient's physiological condition for reference only and no therapeutic decisions should be made based solely on the GHI algorithm predictions") implies a non-standalone, assistive role, but explicit standalone performance studies are not part of this submission's provided information.
7. Type of Ground Truth Used
- "No new clinical testing was performed." Therefore, for this specific 510(k) submission, no new patient-level ground truth (expert consensus, pathology, outcomes data, etc.) was established for performance evaluation of new algorithms or features. The verification activities relied on bench simulations and usability testing, not clinical ground truth.
8. Sample Size for the Training Set
- The document pertains to the clearance of a device (HemoSphere Alta Advanced Monitoring Platform) with software modifications and hardware integration, not the development or training of new AI algorithms. Therefore, no information on the sample size of a training set is provided. The algorithms included in the HemoSphere Alta system (e.g., GHI, HPI, CAI) would have been developed and trained using data sets prior to their initial clearance. This current 510(k) does not detail those previous training sets.
9. How the Ground Truth for the Training Set Was Established
- Similar to the training set sample size, this information is not provided in this 510(k) document, as it focuses on software updates and hardware integration to an already cleared platform, not the initial development and training of novel algorithms.

The provided FDA 510(k) clearance letter and summary for the Fetal & Maternal Monitor (F15A, F15A Air) do not contain the detailed information necessary to fully answer all aspects of your request regarding acceptance criteria and the study that proves the device meets them.
The document focuses primarily on demonstrating substantial equivalence to a predicate device (Edan Instruments, Inc., F9 Express Fetal & Maternal Monitor, K173042) through comparison of intended use, technological characteristics, and conformance to various safety and performance standards. It mentions "functional and system level testing to validate the performance of the devices" and "results of the bench testing show that the subject device meets relevant consensus standards," but it does not specify quantitative acceptance criteria for each individual physiological parameter (e.g., FHR accuracy, SpO2 accuracy) nor the specific results of those tests beyond stating that they comply with standards.
Specifically, the document does not include information on:
- A table of acceptance criteria with specific quantitative targets for each parameter and the reported device performance values against those targets. It only states compliance with standards.
- Sample sizes used for a "test set" in the context of clinical performance evaluation (it mentions "bench testing," but this is typically laboratory-based and doesn't involve patient data in a "test set" sense for AI/algorithm performance validation).
- Data provenance for such a test set (e.g., country of origin, retrospective/prospective).
- Number or qualifications of experts used to establish ground truth.
- Adjudication methods.
- Multi-Reader Multi-Case (MRMC) studies or human reader improvement data with AI assistance.
- Standalone (algorithm-only) performance, as this is a monitoring device, not a diagnostic AI algorithm.
- Type of ground truth (beyond "bench testing" which implies engineered signals or controlled environments).
- Sample size for a training set or how ground truth for a training set was established. This device is a traditional medical device, not an AI/ML-driven diagnostic or interpretative algorithm in the way your request implies.
Therefore, based solely on the provided text, I can only address what is present or infer what is missing.
Here's a breakdown based on the available information:
Analysis of Acceptance Criteria and Performance Testing based on Provided Document
The provided 510(k) summary focuses on demonstrating substantial equivalence to a predicate device (F9 Express Fetal & Maternal Monitor, K173042) by showing that the new device (F15A, F15A Air) has the same intended use and fundamentally similar technological characteristics, with any differences not raising new safety or effectiveness concerns.
1. A table of acceptance criteria and the reported device performance
The document does not provide a specific table with quantitative acceptance criteria for each physiological parameter (e.g., FHR accuracy, SpO2 accuracy) and the corresponding reported performance values obtained in testing. Instead, it states that the device was assessed for conformity with relevant consensus standards. For example, it lists:
- IEC 60601-2-37:2015: Particular requirements for the basic safety and essential performance of ultrasonic medical diagnostic and monitoring equipment (relevant for FHR).
- ISO 80601-2-61:2017+A1:2018: Particular requirements for basic safety and essential performance of pulse oximeter equipment (relevant for SpO2).
- ISO 80601-2-56:2017+A1:2018: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement (relevant for TEMP).
- IEC 60601-2-27:2011: Particular requirements for the basic safety and essential performance of electrocardiographic monitoring equipment (relevant for MECG/DECG).
Acceptance Criteria (Inferred from standards compliance): The acceptance criteria are implicitly the performance requirements specified within these listed consensus standards. These standards set limits for accuracy, precision, response time, and other performance metrics for each type of measurement.
Reported Device Performance: The document states: "The results of the bench testing show that the subject device meets relevant consensus standards." This implies that the measured performance statistics (e.g., accuracy, bias, precision) for each parameter fell within the acceptable limits defined by the respective standards. However, the specific measured values are not provided in this summary.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document mentions "Bench Testing" which implies laboratory-based testing using simulators, controlled signals, or phantoms, rather than a "test set" involving patient data. There is no information provided regarding:
- Sample size (e.g., number of recordings, duration of recordings, number of simulated cases) for the bench tests for each parameter.
- Data provenance (e.g., country of origin, retrospective or prospective) as this is not a study involving patient data collection for performance validation.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This is not applicable and not provided. For a traditional physiological monitor, ground truth for bench testing is typically established using:
- Calibrated reference equipment/simulators: e.g., ECG simulators to generate known heart rates, SpO2 simulators to generate known oxygen saturation levels.
- Physical standards/phantoms: e.g., temperature baths at known temperatures.
- Known physical properties: e.g., precise weights for pressure transducers.
Clinical experts are not involved in establishing ground truth for bench performance of these types of physiological measurements.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable and not provided. Adjudication methods are relevant for human expert review of complex clinical data (e.g., medical images for AI validation) to establish a consensus ground truth. For bench testing of physiological monitors, ground truth is objectively determined by calibrated instruments or defined physical parameters.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable and not provided. An MRMC study is typically performed to evaluate the diagnostic accuracy of AI-assisted human interpretations versus unassisted human interpretations for AI-driven diagnostic devices. The Fetal & Maternal Monitor is a physiological monitoring device, not an AI-assisted diagnostic imaging or interpretation system. It measures and displays physiological parameters; it does not provide AI-driven assistance for human "readers" to interpret complex clinical information.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The device is a monitor that directly measures physiological parameters. It is not an "algorithm only" device in the sense of an AI model providing a diagnostic output. Its performance (e.g., FHR accuracy) is its standalone performance, as it directly measures these parameters. The document states "functional and system level testing to validate the performance of the devices," which would represent this type of standalone performance for the measurement functionalities. However, specific quantitative results are not given, only compliance with standards.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
As explained in point 3, the ground truth for bench testing of physiological monitors is established using calibrated reference equipment/simulators and physical standards.
8. The sample size for the training set
This is not applicable and not provided. This device is a traditional physiological monitor, not a machine learning model that requires a "training set." Its algorithms for parameter measurement are based on established physiological principles and signal processing techniques, not on statistical learning from large datasets.
9. How the ground truth for the training set was established
This is not applicable and not provided for the same reasons as point 8.

| 21 CFR 880.2910
The monitors are intended to be used for monitoring, storing, recording, and reviewing of, and to generate alarms for, multiple physiological parameters of adults and pediatrics (including neonates). The monitors are intended for use by trained healthcare professionals in hospital environments.
The monitored physiological parameters include: ECG, respiration (RESP), temperature (TEMP), functional oxygen saturation of arterial hemoglobin (SpO₂), pulse rate (PR), non-invasive blood pressure (NIBP), invasive blood pressure (IBP), carbon dioxide (CO2), and cardiac output (C.O.).
The arrhythmia detection and ST Segment analysis are intended for adult patients.
The NIBP monitoring supports iCUFS algorithm and iFAST algorithm. The iCUFS algorithm is intended for adult, pediatric and neonatal patients. The iFAST algorithm is intended for adult and pediatric patients (≥3 years of age). Both measurement algorithms are also intended for use with pregnant women, including pre-eclamptic patients. NIBP MAP is not applicable to pregnant women.
The Spot Temp with T2A module can only measure temperature of adult and pediatric (> 1 year of age) patients.
The monitors are not intended for MRI environments.
The cardiac output (C.O.) is only intended for adult patients.
The CX&UX series Patient Monitor including CX10/CX12/CX15/UX10/UX12/UX15 can perform long-time continuous monitoring of multiple physiological parameters. Also, it is capable of storing, displaying, analyzing and controlling measurements, and it will indicate alarms in case of abnormalities so that doctors and nurses can respond to the patient's situation as appropriate.
Minor differences from the predicate device are limited to some modifications of monitoring parameter specifications. These updates do not change the fundamental scientific technology of the cleared predicate device and thus do not raise any questions about the safety and effectiveness of the subject device.
The provided FDA 510(k) clearance letter details the device's technical specifications and comparisons to predicate devices, along with the non-clinical performance data and adherence to various IEC and ISO standards. However, it explicitly states: "Clinical data: The subject device did not require new clinical studies to support substantial equivalence."
This means that the submission for this Patient Monitor device (CX10, CX12, CX15, UX10, UX12, UX15) relies on demonstrating substantial equivalence to a legally marketed predicate device (Edan Instruments, Inc., Patient Monitor Model iX10, iX12, iX15, K232962) through non-clinical performance testing and software verification/validation, rather than new clinical trials or studies involving human patients.
Therefore, the requested information regarding acceptance criteria and studies that prove the device meets acceptance criteria through clinical performance (e.g., sample size for test set, expert involvement, MRMC studies, ground truth establishment for test/training sets, effect size of human reader improvement with AI) cannot be extracted from this document, as such clinical studies were explicitly not required for this 510(k) submission.
The document focuses on demonstrating that the new device's technical specifications and performance are similar to the predicate device, and that it complies with relevant safety and performance standards through bench testing.
Here's what can be extracted from the provided text regarding acceptance criteria and the type of study performed, specifically focusing on the non-clinical aspects:
Device: Patient Monitor (CX10, CX12, CX15, UX10, UX12, UX15)
The acceptance criteria for this device are implicitly tied to its performance meeting the standards and accuracy specifications of the predicate device and relevant international standards. Since no new clinical studies were conducted, the "proof" comes from non-clinical bench testing and software validation.

2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: Not applicable in terms of human subjects or patient data test sets, as "new clinical studies" were not required. The "test set" refers to bench testing and functional system-level validation. The specific number of test cycles or a detailed breakdown of test cases for bench testing is not provided in this summary.
- Data Provenance: The data primarily originates from Edan Instruments Inc. (Shenzhen, Guangdong, China) through internal engineering and quality assurance processes for non-clinical bench testing and software validation. It is not patient data, so concepts like "retrospective or prospective" do not apply.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- Not applicable for clinical ground truth: Since no clinical studies were performed requiring human interpretation or diagnosis for a test set, no medical experts (e.g., radiologists) were used to establish ground truth in this context.
- Internal experts: Bench testing and software validation would have involved engineers and quality assurance professionals, whose qualifications are implicit in the quality system (21 CFR Part 820) but not specified in detail here.
4. Adjudication Method for the Test Set:
- Not applicable: Adjudication methods (e.g., 2+1, 3+1) are relevant for clinical studies involving multiple readers. This was not a clinical study. Bench testing relies on established technical specifications and standard compliance.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done:
- No: No MRMC study was performed as no new clinical studies were required or conducted. Therefore, there's no effect size of human readers improving with AI assistance. The device is a patient monitor, not an AI-assisted diagnostic tool.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was Done:
- Yes (for the technical components): The "performance testing-Bench" effectively represents a standalone evaluation of the device's functional components (ECG, NIBP, SpO2, etc.) and software against defined technical specifications and standards. The "software verification and validation testing" also represents a standalone evaluation of the algorithm and software functions. The specific algorithms (e.g., iCUFS, iFAST for NIBP, arrhythmia analysis logic) are tested independently for their accuracy against known inputs or reference standards as part of bench testing.
7. The Type of Ground Truth Used:
- Technical/Reference Standards: For the bench testing, the "ground truth" would be derived from:
- Reference standards/simulators: Calibrated medical equipment, physiological simulators, and test signals (e.g., known ECG waveforms, simulated blood pressure readings, temperature standards) are used to provide the "true" values against which the device's measurements are compared.
- Defined specifications: The device's internal design specifications and the requirements of the referenced IEC/ISO standards serve as the "ground truth" for compliance testing.
- Not clinical ground truth: No expert consensus, pathology, or outcomes data from real patients were used for establishing ground truth for this submission.
8. The Sample Size for the Training Set:
- Not applicable: The device is a patient monitor, not a machine learning/AI algorithm that typically undergoes a distinct "training" phase with a large dataset. Its functionality is based on established physiological measurement principles and programmed algorithms. Any internal calibration or algorithm refinement would be part of the product development process, not a dedicated "training set" in the AI/ML sense.
9. How the Ground Truth for the Training Set Was Established:
- Not applicable: As there was no "training set" in the context of an AI/ML model, the concept of establishing ground truth for it does not apply to this 510(k) submission.
In summary, this 510(k) clearance relies on demonstrating that the new Patient Monitor is substantially equivalent to a previously cleared predicate device, primarily through robust non-clinical bench testing and software validation, proving compliance with established medical device standards and functional specifications. No new clinical studies with patient data were required or conducted for this specific submission.

The HemoSphere Advanced Monitor was designed to simplify the customer experience by providing one platform with modular solutions for all hemodynamic monitoring needs. The user can choose from available optional sub-system modules or use multiple sub-system modules at the same time. This modular approach provides the customer with the choice of purchasing and/or using specific monitoring applications based on their needs. Users are not required to have all of the modules installed at the same time for the platform to function.
The provided FDA 510(k) clearance letter and summary for the Edwards Lifesciences HemoSphere Advanced Monitor (HEM1) and associated components outlines the device's indications for use and the testing performed to demonstrate substantial equivalence to predicate devices. However, it does not contain the detailed acceptance criteria or the specific study results (performance data) in the format typically required to answer your request fully, especially for acceptance criteria and performance of an AI/algorithm-based feature like the Hypotension Prediction Index (HPI) or Assisted Fluid Management (AFM).
The document states:
- "Completion of all verification and validation activities demonstrated that the subject devices meet their predetermined design and performance specifications."
- "Measured and derived parameters were tested using a bench simulation. Additionally, system integration and mechanical testing was successfully conducted to verify the safety and effectiveness of the device. All tests passed."
- "Software verification testing was conducted, and documentation was provided per FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". All tests passed."
This indicates that internal performance specifications were met, but the specific metrics, thresholds, and study designs for achieving those specifications are not detailed in this public summary.
Therefore, I cannot populate the table with specific numerical performance data against acceptance criteria for the HPI or AFM features, nor can I provide details on sample size, expert ground truth establishment, or MRMC studies, as this information is not present in the provided text.
The text primarily focuses on:
- Substantial equivalence to predicate devices.
- Indications for Use for various HemoSphere configurations and modules.
- Description of software and hardware modifications (e.g., integration of HPI algorithm, new finger cuffs).
- General categories of testing performed (Usability, System Verification, Electrical Safety/EMC, Software Verification) with a blanket statement that "All tests passed."
Based on the provided document, here's what can and cannot be stated:
1. A table of acceptance criteria and the reported device performance
Cannot be provided with specific numerical data or thresholds from the given text. The document only states that "all verification and validation activities demonstrated that the subject devices meet their predetermined design and performance specifications." No specific acceptance criteria values (e.g., "Accuracy > X%", "Sensitivity > Y%", "Mean Absolute Error < Z") or reported performance values are publicly disclosed in this summary for any parameter, including HPI or AFM. For measured and derived parameters (like CO, MAP, etc.), it states they were tested using bench simulation, and "All tests passed," implying they met internal accuracy specifications for physical measurements, but these are not detailed.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Cannot be provided from the given text. The document mentions "bench simulation" for measured and derived parameters, but does not provide sample sizes for these, or the type/provenance of data for testing the HPI or AFM algorithms.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Cannot be provided from the given text. The document doesn't describe the process of establishing ground truth for the algorithms, nor does it mention the number or qualifications of experts involved in such a process.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Cannot be provided from the given text. There is no mention of adjudication methods for any test sets.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Cannot be provided from the given text. The document does not describe any MRMC studies or human-in-the-loop performance evaluation regarding the HPI or AFM features. The HPI and AFM features are described as providing "physiological insight" and "suggestions," not as tools requiring reader interpretation in a comparative effectiveness study as typically seen with imaging AI.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Likely yes, based on the nature of the algorithms, but no specific performance metrics are provided. The HPI and AFM features are stated to provide "quantitative information" and "suggestions." The text indicates "System Verification (Non-Clinical Performance)" and "Software Verification" were performed, suggesting standalone evaluation against internal specifications, but no detailed results are provided. The HPI algorithm itself was "previously cleared in K230057," implying its standalone performance would have been evaluated during that prior clearance, but those details are not in this document.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Cannot be definitively stated from the given text. For the HPI feature, which predicts future hypotensive events, ground truth would typically involve actual patient outcomes (e.g., observed hypotensive events). For AFM, which suggests response to fluid therapy, ground truth might involve observed physiological responses to fluid boluses. However, the document does not specify how these ground truths were established for the purpose of testing the algorithms.
8. The sample size for the training set
Cannot be provided from the given text. The document does not mention details about the training data for the algorithms.
9. How the ground truth for the training set was established
Cannot be provided from the given text. The document does not mention details about the training data or its ground truth establishment.
Summary of Device Features Mentioned in Relation to Performance/Testing (General):
- HemoSphere Advanced Monitor and various modules/accessories: The document primarily describes this as a monitoring platform for various hemodynamic parameters (CO, SvO2, MAP, etc.). Performance for these measured and derived parameters was tested via "bench simulation," and "All tests passed," implying they met internal benchmarks for accuracy and reliability.
- Acumen Hypotension Prediction Index (HPI) software feature: This feature provides "physiological insight into a patient's likelihood of future hypotensive events." It was integrated from a previously cleared device (K230057). The document states "There are no changes to the Acumen HPI algorithm from what was cleared in K230057." This implies that the acceptance criteria and supporting studies for the HPI algorithm itself would be found in the K230057 clearance documentation, not typically resubmitted in detail for integration into another platform unless the integration process significantly altered its functionality or intended use.
- Acumen Assisted Fluid Management (AFM) software feature: This feature provides "physiological insight into a patient's estimated response to fluid therapy" and "suggestions." It also mentions "Acumen AFM fluid administration suggestions are offered to the clinician; the decision to administer a fluid bolus is made by the clinician, based upon review of the patient's hemodynamics. No therapeutic decisions should be made based solely on the Assisted Fluid Management suggestions." This language suggests it's a supportive, advisory tool, rather than a diagnostic one requiring strict accuracy metrics in the same way. No performance specifics for AFM are given.
- Usability Study: Conducted to ensure primary operating functions and critical tasks can be performed without patient or user harm. Determined that "intended users can perform primary operating functions and critical tasks of the system without any usability issues that may lead to patient or user harm." This is an acceptance criterion for human factors, but not for algorithmic performance.
- Electrical Safety and EMC, Software Verification: All tests passed. These are general product safety and quality criteria, not specific to the performance of the predictive algorithms.
To obtain the detailed performance data, acceptance criteria, sample sizes, and ground truth information for the HPI or AFM algorithms, one would typically need to refer to the original 510(k) submission for the HPI algorithm (K230057) and potentially separate documentation for the AFM feature, which are not included in this general clearance letter for the HemoSphere platform update.

The monitor B105M, B125M, B155M, B105P and B125P are portable multi-parameter patient monitors intended to be used for monitoring, recording, and to generate alarms for multiple physiological parameters of adult, pediatric, and neonatal patients in a hospital environment and during intra-hospital transport.
The monitor B105M, B125M, B155M, B105P and B125P are intended for use under the direct supervision of a licensed health care practitioner.
The monitor B105M, B125M, B155M, B105P and B125P are not Apnea monitors (i.e., do not rely on the device for detection or alarm for the cessation of breathing). These devices should not be used for life sustaining/supporting purposes.
The monitor B105M, B125M, B155M, B105P and B125P are not intended for use during MRI.
The monitor B105M, B125M, B155M, B105P and B125P can be stand-alone monitors or interfaced to other devices via network.
The monitor B105M, B125M, B155M, B105P and B125P monitor and display: ECG (including ST segment, arrhythmia detection, ECG diagnostic analysis and measurement), invasive blood pressure, heart/pulse rate, oscillometric non-invasive blood pressure (systolic, diastolic and mean arterial pressure), functional oxygen saturation (SpO2) and pulse rate via continuous monitoring (including monitoring during conditions of clinical patient motion or low perfusion), temperature with a reusable or disposable electronic thermometer for continual monitoring Esophageal/Nasopharyngeal/Tympanic/Rectal/Bladder/Axillary/Skin/Airway/Room/Myocardial/Core/Surface temperature, impedance respiration, respiration rate, airway gases (CO2, O2, N2O, anesthetic agents, anesthetic agent identification and respiratory rate), Cardiac Output (C.O.), Entropy, neuromuscular transmission (NMT) and Bispectral Index (BIS).

The proposed monitors B105M, B125M, B155M, B105P and B125P are new version of multi-parameter patient monitors developed based on the predicate monitors B105M, B125M, B155M, B105P and B125P (K213490) to provide additional monitored parameter Bispectral Index (BIS) by supporting the additional optional E-BIS module (K052145) which used in conjunction with Covidien BISx module (K072286).
In addition to the added parameter, the proposed monitors also offer below several enhancements:
- Provided data connection with GE HealthCare anesthesia devices to display the parameters measured from anesthesia devices (Applicable for B105M, B125M and B155M).
- Modified Early Warning Score calculation provided.
- Separated low priority alarms user configurable settings from the combined High/Medium/Low priority options.

- Supported alarm light brightness adjustment.
- Supported alarm audio pause by gesture (Not applicable for B105M and B105P).
- Supported automatic screen brightness adjustment.
- Supported network laser printing.
- Continuous improvements in cybersecurity
The proposed monitors B105M, B125M, B155M, B105P and B125P retain equivalent hardware design based on the predicate monitors and removal of the device Trim-knob to better support cleaning and disinfecting while maintaining the same primary function and operation.
Same as the predicate device, the five models (B105M, B125M, B155M, B105P and B125P) share the same hardware platform and software platform to support the data acquisition and algorithm modules. The differences between them are the LCD screen size and configuration options. There is no change from the predicate in the display size.
As with the predicate monitors B105M, B125M, B155M, B105P and B125P (K213490), the proposed monitors B105M, B125M, B155M, B105P and B125P are multi-parameter patient monitors, utilizing an LCD display and pre-configuration basic parameters: ECG, RESP, NIBP, IBP, TEMP, SpO2, and optional parameters which include CO2 and Gas parameters provided by the E-MiniC module (K052582), CARESCAPE Respiratory modules E-sCO and E-sCAiO (K171028), Airway Gas Option module N-CAiO (K151063), Entropy parameter provided by the E-Entropy module (K150298), Cardiac Output parameter provided by the E-COP module (K052976), Neuromuscular Transmission (NMT) parameter provided by E-NMT module (K051635) and thermal recorder B1X5-REC.
The proposed monitors B105M, B125M, B155M, B105P and B125P are not Apnea monitors (i.e., do not rely on the device for detection or alarm for the cessation of breathing). These devices should not be used for life sustaining/supporting purposes. Do not attempt to use these devices to detect sleep apnea.
As with the predicate monitors B105M, B125M, B155M, B105P and B125P (K213490), the proposed monitors B105M, B125M, B155M, B105P and B125P also can interface with a variety of existing central station systems via a cabled or wireless network which implemented with identical integrated WiFi module. (WiFi feature is disabled in B125P/B105P).
Moreover, same as the predicate monitors B105M, B125M, B155M, B105P and B125P (K213490), the proposed monitors B105M, B125M, B155M, B105P and B125P include features and subsystems that are optional or configurable, and it can be mounted in a variety of ways (e.g., shelf, countertop, table, wall, pole, or head/foot board) using existing mounting accessories.
The provided FDA 510(k) clearance letter and summary for K242562 (Monitor B105M, Monitor B125M, Monitor B155M, Monitor B105P, Monitor B125P) do not contain information about specific acceptance criteria, reported device performance metrics, or details of a study meeting those criteria for any of the listed physiological parameters or functionalities (e.g., ECG or arrhythmia detection).
Instead, the documentation primarily focuses on demonstrating substantial equivalence to a predicate device (K213490) by comparing features, technology, and compliance with various recognized standards and guidance documents for safety, EMC, software, human factors, and cybersecurity.
The summary explicitly states: "The subject of this premarket submission, the proposed monitors B105M/B125M/B155M/B105P/B125P did not require clinical studies to support substantial equivalence." This implies that the changes introduced in the new device versions were not considered significant enough to warrant new clinical performance studies or specific quantitative efficacy/accuracy acceptance criteria beyond what is covered by the referenced consensus standards.
Therefore, I cannot provide the requested information from the given text:
- A table of acceptance criteria and the reported device performance: This information is not present. The document lists numerous standards and tests performed, but not specific performance metrics or acceptance thresholds.
- Sample size used for the test set and the data provenance: Not explicitly stated for performance evaluation, as clinical studies were not required. The usability testing mentioned a sample size of 16 US clinical users, but this is for human factors, not device performance.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable, as detailed performance studies requiring expert ground truth are not described.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
- If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a patient monitor, not an AI-assisted diagnostic tool that would typically involve human readers.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: The document describes "Bench testing related to software, hardware and performance including applicable consensus standards," which implies standalone testing against known specifications or simulated data. However, specific results or detailed methodologies for this type of testing are not provided beyond the list of standards.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not explicitly stated for performance assessment. For the various parameters (ECG, NIBP, SpO2, etc.), it would typically involve reference equipment or validated methods as per the relevant IEC/ISO standards mentioned.
- The sample size for the training set: Not applicable, as this is not an AI/ML device that would require explicit training data in the context of this submission.
- How the ground truth for the training set was established: Not applicable.
In summary, the provided document focuses on demonstrating that the new monitors are substantially equivalent to their predicate through feature comparison, adherence to recognized standards, and various non-clinical bench tests (e.g., hardware, alarms, EMC, environmental, reprocessing, human factors, software, cybersecurity). It does not contain the detailed performance study results and acceptance criteria typically found for novel diagnostic algorithms or AI-driven devices.

The Ear Thermometer is intended to measure human body temperature of people over three months from surface of eardrum. It applies to both professional use and home use.
The ear thermometer is a handheld device that displays the temperature of the measured patient by measuring the thermal radiation of the eardrum. Measurement unit: °C or °F. The results can be displayed on LCD. The thermometers are powered by 1.5V×2 (AAA or AA) alkaline batteries, which can be used for people over three months. A thermopile sensor is employed to detect or monitor the infrared thermal energy emitted from the eardrum, which is converted into temperature measurement with the unit of °C or °F. All the models share the same critical components, intended use, working principle and similar product design, and compose of a sensor, PCB, buttons, LCD display and housing. Functions include temperature measurement, memory reading recall, unit switch, low battery detection and high temperature indicator.
The FDA 510(k) clearance letter and accompanying 510(k) Summary for the Ear Thermometers (EAR-E101, EAR-E102, EAR-E103) provide information on acceptance criteria and supporting studies.
1. Table of Acceptance Criteria and Reported Device Performance:
The document primarily focuses on demonstrating substantial equivalence to a predicate device (Jiangsu Yuyue Medical Equipment & Supply Co., Ltd, Infrared Ear Thermometers YHT101 and YHT200, K203583). Thus, the "acceptance criteria" are largely framed as demonstrating equivalence or adherence to relevant standards. The performance data is presented in comparison to the predicate and overall compliance with standards.
| Acceptance Criteria (Stated or Implied by Comparison) | Reported Device Performance (Subject Device) |
|---|---|
| Accuracy (Clinical) | Measurement Range: 32.0℃~42.9℃ (89.6°F-109.2°F) Accuracy: ±0.2℃/±0.4°F (for 32.0℃ to 42.9℃) |
| Biocompatibility | Passed Cytotoxicity, Sensitization, and Irritation tests per ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 10993-23 |
| Electrical Safety | Compliant with IEC 60601-1, IEC 60601-1-11, ISO 80601-2-56 |
| Electromagnetic Compatibility (EMC) | Compliant with IEC 60601-1-2 |
| Operating Environments | Temperature: 15°C~ 40°C Humidity: ≤ 85% RH, non-condensing Atmospheric pressure: 70–106 kPa |
| Transport and Storage Environments | Ambient Temperature: -20°C to 55°C Relative Humidity: ≤ 93% RH, non-condensing Atmospheric pressure: 50 kPa to 106 kPa |

2. Sample size used for the test set and the data provenance:
- Non-clinical Data (Bench Testing): The document does not specify a "sample size" in terms of number of devices for bench testing. It states that "The device has been tested according to the following standards," implying tests were performed on representative samples to ensure compliance.
- Clinical Data: The summary states, "The clinical testing has been conducted per ISO 80601-2-56 Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement." However, the specific sample size (number of patients/measurements) and data provenance (e.g., country of origin, retrospective/prospective) for this clinical study are NOT provided in the given document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Clinical Data: The document does not specify the number of experts or their qualifications for establishing ground truth in the clinical study. As it's an ear thermometer, the "ground truth" would typically come from a reference temperature measurement method (e.g., rectal thermometry) rather than expert interpretation of an image or signal.
4. Adjudication method for the test set:
- Clinical Data: Given that the device measures a quantitative value (temperature), an adjudication method in the context of expert consensus (like multiple readers for an image) is generally not applicable. The comparison would be between the device's reading and the reference method's reading. The document does not describe any specific adjudication method for the clinical test set.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No, an MRMC comparative effectiveness study was NOT done. This type of study (MRMC) is relevant for diagnostic imaging devices where human interpretation plays a significant role, sometimes aided by AI. This document is for an ear thermometer, a direct measurement device, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, a standalone performance was done for the ear thermometer. The device itself is designed to provide temperature readings directly, without requiring human interpretation or input to calculate the core measurement. The bench and clinical testing described aim to quantify this standalone performance in terms of accuracy and adherence to standards.
7. The type of ground truth used:
- Clinical Data: While not explicitly stated, for a clinical thermometer, the ground truth for performance testing is typically established by comparison against a standardized, highly accurate reference thermometer (e.g., a rectal thermometer or an oral thermometer with known accuracy) or a specialized blackbody calibrator in a controlled environment as specified by standards like ISO 80601-2-56. The document mentions "clinical accuracy test" and "performance test," strongly implying such a comparative methodology.
8. The sample size for the training set:
- Not applicable / Not provided. The device is an ear thermometer, which is a sensor-based measurement tool, not an AI/machine learning algorithm that requires a "training set" in the conventional sense. The device's performance is determined by its design, calibration, and adherence to physical principles and engineering specifications, which are validated through bench and clinical testing.
9. How the ground truth for the training set was established:
- Not applicable. As noted above, the concept of a "training set" and its associated ground truth establishment is not relevant for this type of medical device submission.
