The provided text is a 510(k) premarket notification for a patient monitor and does not contain the detailed clinical study information typically found for devices with specific performance claims related to diagnostic accuracy (like computer-aided detection/diagnosis systems).

The Fukuda Denshi DynaScope Model DS-8000 Series Patient Monitor is a physiological monitoring device that measures various parameters. The 510(k) submission primarily focuses on establishing substantial equivalence to predicate devices. This means that instead of conducting new clinical trials to prove efficacy, the manufacturer demonstrates that their device is as safe and effective as devices already on the market, usually by showing it has the same technological characteristics and meets established performance standards.

Therefore, many of the requested details about acceptance criteria, clinical study design, sample sizes, expert ground truth, and comparative effectiveness studies are not explicitly present in this document because the device's approval hinges on demonstrating equivalence through testing to standards and internal verification rather than de novo clinical performance studies for AI algorithms.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't present a table of specific acceptance criteria or quantitative performance metrics in the way one might see for a diagnostic AI device (e.g., sensitivity, specificity, AUC). Instead, it states that the device was subjected to "extensive safety, environmental and performance testing" to ensure "all functional and performance specifications were met." This implies the acceptance criteria were compliance with a range of standards and internal functional specifications.

Reported Device Performance (Implicit): The device is considered to perform "as well as the legally marketed predicate devices" because it incorporates identical technology or modules from previously cleared devices and complies with relevant standards.

2. Sample Size Used for the Test Set and Data Provenance:

• Sample Size: Not specified. The testing mentioned refers to "final testing for the device" and "host tested at the previously noted OEM engineering test facility," which typically involve engineering verification and validation on a limited set of test inputs or simulated data, rather than a large patient-based test set for performance claims.
• Data Provenance: Not specified, but given the nature of the device (physiological monitor), testing would likely involve simulated physiological signals and possibly a small number of human subjects for usability and basic functionality, not large-scale retrospective or prospective patient data for algorithm performance validation.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

This level of detail about expert-established ground truth is not applicable to this type of submission. The device is a physiological monitor, where parameters like ECG, heart rate, or blood pressure are measured directly using established sensor technologies, and their accuracy is typically validated against known reference standards or other calibrated devices, not through expert consensus on interpretations.

4. Adjudication Method for the Test Set:

Not applicable for the same reasons as #3.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance:

An MRMC study is not applicable. This device is a monitor, not an AI-assisted diagnostic tool that interprets or provides clinical recommendations for human readers. It provides raw and processed physiological data. The document does not mention any AI components that would assist human readers in interpretation or diagnosis.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

The device itself is a standalone physiological monitor. Its performance is evaluated on its ability to accurately measure and display physiological parameters. The "algorithms" mentioned (e.g., NIBP, 12-Lead ECG analysis software, SpO2) are components embedded in the device, and their performance is considered based on their prior clearance or established standards for those specific modules. No specific "algorithm-only" performance study distinct from the device's overall function is described.

7. The Type of Ground Truth Used:

For physiological measurements, the ground truth would typically be:

• Reference Standards: Calibrated instruments for known values (e.g., blood pressure cuffs calibrated against a mercury manometer, ECG simulators generating known waveforms).
• Predicate Device Comparison: Comparing measurements from the new device to those from a legally marketed predicate device.
• Pathology/Outcomes Data: Not typically used for a physiological monitor of this type.

The document states that the new device's NIBP measurement utilizes the "exact same technology and algorithm" as a previously approved monitor, and the 12-Lead ECG monitoring uses the "same" software module as a previous device. This implies that the ground truth for these components was established during the clearance of those predicate devices, likely through comparison to reference standards or established clinical methods.

8. The Sample Size for the Training Set:

This information is not applicable. The device is a physiological monitor built from established technologies and previously cleared modules. It does not describe a machine learning or AI model that requires a distinct "training set" in the context of contemporary AI/ML device development. The underlying algorithms for parameters like ECG analysis or pulse oximetry are fixed and well-understood.

9. How the Ground Truth for the Training Set Was Established:

Not applicable, as there is no mention of a distinct training set for an AI/ML algorithm within the context of this 510(k) submission. The ground truth for the components of the device (e.g., 12-Lead ECG analysis) would have been established during the development and clearance of those original component technologies, likely through extensive testing against known physiological signals and clinical validation studies at that time.

The Fukuda Denshi DynaScope Model DS-8100N/8100M Patient Monitor is a multi-parameter patient monitor. The provided document doesn't detail specific acceptance criteria and the associated study results for each parameter within the device. Instead, it offers a general statement that the device has undergone "extensive safety, environmental and performance testing" to ensure all functional and performance specifications are met. It also states that OEM engineering test facilities confirmed the performance and functional specifications for their supplied modules.

The conclusion asserts that the device is "as safe and effective and performs as well as the legally marketed predicate devices" based on "laboratory testing, validation, and risk analysis." This implies a comparative study against predicate devices and adherence to various safety and performance standards, rather than proving performance against predefined quantitative acceptance criteria with specific metrics.

Here's a breakdown of the available information based on your request, even though specific quantitative acceptance criteria are not provided in the document:

1. Table of Acceptance Criteria and Reported Device Performance

As specific quantitative acceptance criteria are not explicitly stated in the provided text for each parameter (ECG, NIBP, SpO2, etc.), a table cannot be fully constructed with precise numbers. The document generally states that "all functional and performance specifications were met."

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify the sample size used for any test set or the data provenance (e.g., country of origin, retrospective/prospective). It generally refers to "various performance tests" and "OEM engineering test facility" testing.

3. Number of Experts and Qualifications for Ground Truth

The document does not mention the number of experts used to establish ground truth or their qualifications. The testing appears to be primarily technical and performance-based against established standards and predicate device performance, not reliant on expert clinical interpretation for ground truth.

4. Adjudication Method

The document does not describe any adjudication method. This is typically relevant for studies involving human interpretation or subjective assessments, which are not detailed here.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A multi-reader multi-case (MRMC) comparative effectiveness study was not explicitly mentioned or described. The device is a patient monitor, and its evaluation would generally focus on the accuracy of its physiological measurements against reference standards, rather than the improvement of human reader performance with AI assistance. The document focuses on performance specifications and equivalency to predicate devices.

6. Standalone (Algorithm Only) Performance Study

A standalone performance study was implicitly done for various parameters (e.g., SpO2, CO2, ECG performance) by testing against relevant standards (e.g., ANSI/AAMI EC13 for ECG, ISO 9919 for pulse oximeters). The document states: "Final testing for the device included various performance test for the device designed to insure that all functional and performance specifications were met." This refers to the device's ability to accurately measure and display physiological data.

7. Type of Ground Truth Used

The ground truth for the performance testing appears to be based on:

• Reference standards/simulators: This is typical for physiological monitors, where the device's measurements are compared against highly accurate reference instruments or simulated physiological signals.
• Performance of predicate devices/OEM modules: The document explicitly states the device utilizes technologies "incorporated into previously cleared devices and OEM manufactured module" and that performance was confirmed by OEM test facilities. This implies comparison against the established performance of those components.

8. Sample Size for the Training Set

The document does not mention a training set sample size. This is likely because the device is a patient monitor that measures physiological parameters, not an AI/ML device that requires a large dataset for training a diagnostic algorithm. The algorithms for signal processing and measurement in patient monitors are typically deterministic or based on established physiological models, not machine learning that would involve a "training set."

9. How Ground Truth for the Training Set Was Established

Since no training set is mentioned (as the device is not described as using machine learning that requires one), the document does not describe how ground truth for a training set was established.

The device is intended to be used on adult population only.

The device is not intended for home use.

The Fukuda Denshi VaSera model VS-1500AU is a prescriptive device intended for use by health care professionals. It is designed to be used to assist the clinician in the detection of peripheral vascular diseases and has been designed and tested to automate published clinical diagnostic test methods. The device is capable of measuring non-invasive blood pressures, non-invasive pulse volume recordings and heart sounds. In addition, the device is capable of calculating specific clinically recognized indices such as ABI (Ankle Brachial Index), TBI (Toe Brachial Index) and pulse wave velocity.

The provided text describes a 510(k) summary for the Fukuda Denshi VaSera Model VS-1500AU. However, it does not contain specific acceptance criteria or the detailed results of a study that proves the device meets such criteria.

The document states: "Final testing for the device included various performance tests, including clinical validation using the predicate device, to insure that all functional and performance specifications were met." and "In conclusion, drawing from laboratory testing, validation and risk Analysis, the Fukuda Denshi VaSera model VS-1500AU demonstrates that this device is as safe and effective and performs as well as the legally marketed predicate devices..."

This indicates that a study (clinical validation) was performed, and the results were found to be satisfactory for substantial equivalence. However, the details of this study, including specific acceptance criteria as quantitative metrics (e.g., minimum sensitivity, specificity, accuracy, or correlation coefficients) and the reported device performance against those criteria, are not provided in this summary.

Therefore, I cannot populate the table or answer many of the questions directly from the provided text.

Here's a breakdown of what can and cannot be answered based on the input:

1. Table of acceptance criteria and reported device performance:

2. Sample size used for the test set and the data provenance:

• Sample Size (Test Set): Not specified.
• Data Provenance: Not specified (e.g., country of origin, retrospective or prospective). The text only mentions "clinical validation using the predicate device."

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not specified. The study relied on comparison to a "predicate device" and potentially its established measurements.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

• Not specified.

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:

• Not applicable. This device is a diagnostic system that automates measurements, not an AI-assisted interpretation system for human readers. The clinical validation was likely a comparison of its measurements to those of the predicate device, not an MRMC study with human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• The "clinical validation using the predicate device" implies a standalone performance assessment of the device's measurements against established methods. The device itself is designed as an automated measurement system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• The "ground truth" for the device's performance would primarily be the measurements obtained from the legally marketed predicate device (Colin Medical VP-1000/2000 and Fukuda Denshi DS-5300 Patient Monitor), as the VaSera VS-1500AU was tested to automate similar diagnostic test methods and was determined to be "as safe and effective and performs as well as" these predicates.

8. The sample size for the training set:

• Not applicable. This is not an AI/ML device that requires a distinct "training set" in the conventional sense. The "validation" mentioned refers to testing the device's algorithms and hardware against established methods, not training a machine learning model.

9. How the ground truth for the training set was established:

• Not applicable, as there is no mention of a training set for an AI/ML model.

The DS-7000 Series Telemetry Monitoring System is intended to be used as central station monitoring system for the evaluation of the cardiovascular system. It is intended to be used by or on the order of a physician or similarly qualified healthcare professional. The DS-7000 Series Telemetry Monitoring System is intended to be used in hospital environments: ER, ICU, a clinic or similar settings. The DS-7000 Series Telemetry Monitoring System is intended to be used in those situations where the patient is being monitored by a Fukuda Denshi DS-5000-7000 Series bedside monitor, or patient worn telemetry transmitter where remote, central station monitoring is desired. This system is not intended for home use.

The Fukuda Denshi model LX-7230KM/7230N is a patient worn Transmitter that transmits physiological data such as ECG, respirogram, arterial oxygen saturation (SpO2), plethysmograph, and pulse rate from a patient to a Fukuda Denshi Central Monitor. The front LCD display information such as ECG, heart rate, respirogram, respiration rate, SpO2, plethysmograph, pulse rate, pulse amplitude level, battery level, and the conditions of the ECG electrodes and SpO2 sensor. For the SpO2 measurement, the LX-7230N utilizes Nellcor SpO2 module technology (K060576) and the LX-7230KM utilizes Konica-Minolta SpO2 module technology (K053419). Both transmitters can only be used as an interface device of the previously cleared Fukuda Denshi Central Monitor (K970585, K000746, K020084) utilizing the central telemetry receiver (K980728). Both transmitters utilize digital FSK (frequency shift keying) technology and operate in the WMTS 608 to 614 MHz transmission frequencies. One or two channel ECG waveforms are selectable with lead selection available using the two buttons (Enter and down arrow) on the front panel. (In case of using a 3-electrode lead cable or a 5-electrode chest lead cable). Both transmitters are battery powered using 2 AA alkaline batteries with available continuous operation for 6 days (LX-7230KM) or 3 days (LX-7230N). The LX-7230KM/7230N is small and lightweight at 190 grams including batteries. The physical dimensions of the device are 72 mm (W) x 98 mm (H) x 24.8(D) mm.

This is a summary of the acceptance criteria and study information based on the provided text.

This submission describes a telemetry transmitter (Fukuda Denshi Model LX-7230KM/7230N) which is an interface device that transmits physiological data (ECG, respirogram, arterial oxygen saturation (SpO2), plethysmograph, and pulse rate) from a patient to a central monitor. The core technology (ECG and Respiration measurement) is the same as the predicate device (LX-5630, [K033711](https://510k.innolitics.com/search/K033711)). The SpO2 measurement function integrates OEM modules from Konica Minolta (PULSOX-300/300i, [K053419](https://510k.innolitics.com/search/K053419)) and Nellcor (N-600x Pulse Oximeter, [K060576](https://510k.innolitics.com/search/K060576)), without modification to these modules or their sensors. The submission focuses on demonstrating substantial equivalence to the predicate device and the previously cleared OEM SpO₂ modules rather than presenting new clinical study data with specific performance metrics.

Acceptance Criteria and Device Performance

The provided document does not specify quantitative acceptance criteria (e.g., sensitivity, specificity, accuracy targets) for the Fukuda Denshi Model LX-7230KM/7230N Transmitter. Instead, the claim for substantial equivalence is based on the device incorporating identical fundamental technology for ECG and Respiration measurement as a predicate device and utilizing pre-cleared, unmodified SpO₂ modules whose performance has already been established and accepted by the FDA.

The "reported device performance" indicated is that the device "demonstrates that this device is as safe and effective as and performs as well as the legally marketed predicate device, the Fukuda Denshi model LX-5630 Transmitter 510(k) #K033711." This implies that the device meets the performance standards already established for the predicate device and the incorporated OEM SpO₂ modules.

Study Details

The provided text describes a 510(k) submission seeking substantial equivalence for a medical device by demonstrating that its core technology is the same as a predicate device and that its SpO2 components are pre-cleared, unmodified OEM modules. Therefore, the "study" described is not a new clinical trial with specific performance endpoints, but rather a set of tests to confirm the new device's functionality and safety consistent with its predicate and incorporated components.

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not explicitly stated as a patient-based sample size. The document mentions "extensive safety, environmental and performance testing" and "various performance tests." For the SpO2 modules, it states they were "host tested at the previously noted OEM engineering test facility."
   • Data Provenance: Not specified in terms of country of origin or whether it was retrospective or prospective. The testing appears to be internal validation ("laboratory testing, validation and risk Analysis") and OEM engineering testing.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. The submission relies on technical equivalence to established, cleared devices and modules rather than new ground truth establishment by experts for a new dataset.

3. Adjudication method for the test set: Not applicable. There is no mention of an adjudication process for expert consensus on a test set.

4. 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 telemetry transmitter and does not involve AI or human interpretation of medical images or data requiring an MRMC study.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not explicitly detailed as a "standalone" performance study in the context of an algorithm. The device itself is a standalone transmitter. Its performance is demonstrated through its hardware and software functionality as an interface for physiological data, relying on the established performance of its component parts (ECG/Respiration from predicate, SpO2 from OEM modules).

6. The type of ground truth used: The "ground truth" for this submission is based on the performance established for:

   • The predicate device (Fukuda Denshi model LX-5630 Transmitter, K033711) for ECG and Respiration measurement.
   • The pre-cleared OEM SpO₂ modules (Konica Minolta "Pulsox-300/300i" K053419 and Nellcor "OxiMax N-600x Pulse Oximeter" K060576).
     The ground truth is implicit in the regulatory clearance of these prior devices and modules.

7. The sample size for the training set: Not applicable. This is not an AI/machine learning device that would typically involve a "training set" for an algorithm. The device's functionality uses established physiological measurement technologies.

8. How the ground truth for the training set was established: Not applicable, as there is no training set for an AI algorithm.

Or, by using the option Mainstream CO2 interface Unit (MGU-721), the Capnostat 5 Mainstream CO2 Sensor (K042601) manufactured by Respironics Novametrix, LLC. is allowed to connect to the DS-7210/7210M with serial communication protocol for CO2 monitoring. And, by using the option Unit (HU-71/HU-72/HU-73), invasive blood pressure (up to 5 channels), cardiac output, temperature (up to 3 channels) can be additionally monitored.

For the SpO2 measurement monitoring, the DS-7000 utilizes Nellcor technology (K021090) and the DS-7000M utilizes Masimo one (K033296). No new functions for SpO2 measurement are being added and are not the subject of this submission. This subject modified DS-7210/7210M has the same feature.

The DS-7000 Series Patient Monitor is a self contained monitor which includes a 12.1 inch TFT color LCD display which can display up to 12 (for DS-7000/7000M) or 14 (for DS-7210/7210M) waveforms and up to 20 (for DS-7000/7000M) or 16 (for DS-7210/7210M) numeric displays. Input operation is performed by the touch screen panel, 5 fixed keys (only DS-7000/7000M), or infrared remote-control command (optional). Additional standard features of the DS-7000 Series Patient Monitor include the DS-LAN II connection, which is a proprietary network system based on an Ethernet LAN (K970585), through either a built in Ethernet LAN or external telemetry transmitter (the Fukuda Denshi DS-5000 series telemetry model HLX-501/561, K980728) connection for connection to the Fukuda Denshi Central Station Monitors, a built- in dot matrix thermal printer that can print up to 3 wave forms simultaneously, and an alarm indicator feature on the top of device that alerts to alarm conditions.

Here's an analysis of the provided text regarding the Fukuda Denshi DynaScope Model DS-7000/7000M Patient Monitor.

Based on the provided document, specific acceptance criteria and a detailed study proving the device meets these criteria in terms of analytical or clinical performance are NOT explicitly detailed.

The submission focuses heavily on substantial equivalence to predicate devices and adherence to various safety and performance standards rather than presenting a standalone study with specific performance metrics against pre-defined acceptance criteria.

However, I can extract information related to testing and general claims of performance:

1. Table of Acceptance Criteria and Reported Device Performance

As mentioned, explicit, quantitative acceptance criteria and corresponding reported device performance values (like sensitivity, specificity, accuracy for specific physiological measurements) are not provided in this 510(k) summary. The document focuses on demonstrating that the device is "as safe and effective and performs as well or better than the legally marketed predicate devices."

The "performance testing" mentioned generally refers to ensuring "all functional and performance specifications were met," which implies internal validation against design requirements, but these specific requirements are not listed publicly in this summary.

2. Sample Size Used for the Test Set and Data Provenance

This information is not provided in the document. The text states "Final testing for the device included various performance test for the device designed to insure that all functional and performance specifications were met." This suggests internal validation, but details on sample size or data provenance (e.g., country of origin, retrospective/prospective) are absent.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not provided. Given the nature of a patient monitor, ground truth typically involves direct physiological measurements or calibration standards. However, the document does not elaborate on how "ground truth" was established for any performance testing.

4. Adjudication Method for the Test Set

This information is not provided.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A multi-reader multi-case (MRMC) comparative effectiveness study comparing human readers with and without AI assistance was not mentioned or indicated in the document. This type of study is more common for diagnostic imaging AI rather than for patient monitoring devices.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

A standalone performance study for an algorithm is not explicitly detailed in this document in the way it would be for a diagnostic AI. The device itself is a "patient monitor," implying continuous, standalone measurement of physiological parameters. However, the performance metrics (e.g., accuracy of HR measurement, SpO2 accuracy) are not presented as results of a formal standalone study with acceptance criteria.

The information suggests that the performance of component technologies (like SpO2, multigas) relies on their previous FDA clearances as separate OEM modules which would have undergone their own standalone validation (e.g., Nellcor, Masimo, Criticare).

7. Type of Ground Truth Used

The type of ground truth used for testing is not explicitly stated. For a patient monitor, ground truth would typically involve:

• Direct physiological measurements from reference instruments.
• Calibration standards for accuracy of sensors (e.g., temperature probes, blood pressure cuffs).
• Simulated physiological signals for testing algorithms like arrhythmia detection.

The document mentions that testing ensured "all functional and performance specifications were met," which would imply comparison against a form of ground truth or established standards, but the specific methodologies are not described.

8. Sample Size for the Training Set

This information is not provided. Patient monitors primarily apply established physiological measurement principles and algorithms rather than sophisticated machine learning models that require large "training sets" in the AI sense. While there might be internal algorithm development and tuning, the concept of a "training set" as it applies to deep learning AI is not relevant here, and therefore, no sample size is mentioned.

9. How Ground Truth for the Training Set Was Established

As the concept of a "training set" in the AI sense is not directly applicable to this type of device based on the provided information, the method for establishing ground truth for a training set is not discussed or provided.

Summary of Device Performance and Evidence from the Document:

While specific quantitative acceptance criteria are missing in this public summary, the document asserts that the device meets regulatory requirements through:

• Substantial Equivalence: The primary strategy detailed is demonstrating substantial equivalence to several legally marketed predicate devices (Fukuda Denshi DS-5300, DS-7141, Nellcor OxiMax N-560, Masimo SET RAD 5, Criticare 8500). This implies that the new device's performance is considered comparable to these cleared devices, which would have themselves met their own performance criteria upon clearance.
• Compliance with Standards: The device has been tested to assure compliance with a comprehensive list of general safety, individual product-specific (e.g., ECG, NIBP, SpO2), and EMC standards (UL60601-1, IEC series, ANSI/AAMI series, ISO series). Meeting these standards implies specific performance benchmarks for various physiological parameters (e.g., accuracy requirements for blood pressure, heart rate, SpO2). However, the specific results against these standards are not presented in this summary.
• OEM Module Reliance: Several key functions (SpO2, multigas) utilize previously cleared OEM modules from Nellcor, Masimo, and Criticare. The performance of these modules would have been validated during their own original 510(k) clearances.
• Internal Performance Testing: "Final testing for the device included various performance test ... to insure that all functional and performance specifications were met." This refers to internal company testing against their own design specifications.
• Risk Analysis and Validation: The conclusion states that the device draws from "laboratory testing, validation and risk Analysis" to demonstrate safety and effectiveness.

Recordings can also be initiated from the bedside monitor or from the patient worn transmitters. System functions such as trending, arrhythmia and ST monitoring and data access are available to the user from the central monitor.

The HLX-501 multi-parameter transmitter may provide up to six waveforms and numeric data from the bedside monitor. Parameter monitored may include ECG, SpO2, Resp, BP, NIBP and Temp.

The patient worn LX-5120 transmitter provides monitoring of ECG and Respiration parameters.

The modified transmitter subject to this submission, the patient worn LX-5630 provides ECG and Respiration monitoring identically as the LX-5120 and adds SpO2 transmission through the integration of an Pulse Oximetry OEM module designed and manufactured by Konica Minolta Sensing Inc and cleared as the Minolta Pulseox-3 LI (K010413).

Ask a specific question about this device

Use of the Fukuda Denshi model DS-7141 Portable Patient Monitor is indicated in those situations where observation of one or more of the following parameters on an individual patient may be required. ECG (waveform, heart rate, STlevel and yentricular arrhythmias), respiration, non-invasive and or invasive blood pressure, temperature, pulse oximetry and/or CO2. These observations can include an audible and visual alarm if any of these parameters exceed values that are established by the clinician. The observations may include the individual or comparative trending of one or more of these parameters over a period of up to 24 hours. The DS-7141 is indicated in situations where an instantaneous display of waveform, numeric and trended values is desired. The DS-7141s also indicated where a hard copy record of the physiological parameters, the alarms conditions or the trended values may be required.

The DS-7141 Portable Patient Monitor is a pre-configured monitor meant to acquire and monitor physiological signals from patients. The system is design to be used in ICU, CCU, OR or recovery areas of the hospital or clinic. An optional Battery Pack Operation allows the DS-7141 to be used to rouito, patients during intra-hospital transport. Patient ages from neonates to adults can all be monitored. Waveforms, numeric and trend data from these patients are available to the clinician on the systems display or may be printed on the systems recorder.

The DS-7141 is an addition to the DS-7100 Series Patient Monitor Line up. (K032290). It is the same as the predicate devices in that it uses identical hardware and software which allows for the monitoring of EEC, RESP, SpO2m BP, NIBP and Temp. It additionally includes identical telemetry capabilities as the predicate. The DS-7141 adds EtCo2 monitoring capability to the DS-7100 series of Portable Patient Monitors by the integration of a MediCO2 MicroStream TM module which was designed and manufactured by Oridion and previously cleared under 510(k) (K964239).

The DS-7141is a self contained monitors which include an 8.4 inch TFT color LCD display which can display up to 6 waveforms. All input operation is performed on the monitors touch screen controls. Additional standard features include an Ethernet LAN for connection to Fukuda Denshi Central Stations, a built- in dot matrix thermal printer that can print up to 3 wave forms simultaneously and an alarm pole feature on the top of device that alerts to alarm conditions through 9 corresponding flashing patterns.

The provided text describes a 510(k) submission for the Fukuda Denshi DS-7141 Portable Patient Monitor, focusing primarily on its equivalence to previously cleared devices rather than extensive new clinical studies with detailed acceptance criteria and performance metrics.

Based on the provided information, I can extract the following:

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not explicitly state quantitative acceptance criteria or detailed performance metrics in the format of a table for the DS-7141 itself, beyond general "performance specifications" being met. The core of this submission relies on demonstrating substantial equivalence to predicate devices and adherence to recognized standards.

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify a distinct "test set" with a defined sample size in the context of clinical data for algorithmic performance. The testing described is more aligned with product verification and validation (safety, environmental, performance specifications, and adherence to standards) rather than a clinical trial evaluating algorithmic accuracy against a ground truth dataset in the typical sense of AI/ML device testing.

The provenance of data is not mentioned in terms of country of origin or whether it was retrospective or prospective, as it does not appear to be a study of patient data.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable. This submission is about a patient monitor with integrated components, not an AI/ML diagnostic or prognostic device that relies on expert interpretation of output to establish ground truth for a test set.

4. Adjudication Method for the Test Set

Not applicable. No clinical test set requiring adjudication is described.

5. If a Multi-reader Multi-case (MRMC) Comparative Effectiveness Study was Done

No. The document makes no mention of an MRMC study or any studies involving human readers, with or without AI assistance. The device is a patient monitor, not an interpretive AI system for imaging or other complex data.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Study was Done

Not explicitly a "standalone" algorithmic study in the modern sense. The "host testing" of the integrated MediCO2 MicroStream™ module at the OEM facility would evaluate its performance specifications in isolation before integration, which could be considered a form of standalone testing for that specific component. However, this is for a physiological measurement device, not an AI algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance would be derived from:

• Engineering Specifications and Benchmarks: For parameters like accuracy of measurements (ECG, SpO2, NIBP, Temp, EtCO2), stability, and response times.
• Standardized Test Conditions: Environmental testing (temperature, humidity, vibration), electrical safety tests.
• Reference Devices: Performance of integrated modules (e.g., EtCO2) would be compared to known accurate reference devices or established functional standards.

8. The Sample Size for the Training Set

Not applicable. The document does not describe an AI/ML algorithm that would have a "training set" in the context of machine learning model development.

9. How the Ground Truth for the Training Set was Established

Not applicable, as there is no described training set for an AI/ML algorithm.
