The provided text describes the Sonicaid FM800, a fetal/maternal monitor, and its comparison to predicate devices, but it does not include detailed acceptance criteria or a dedicated study definitively proving the device meets specific performance criteria in the format requested.

Instead, the document focuses on demonstrating substantial equivalence to existing legally marketed devices (Sonicaid FM830 (K002150) and RDT Limited Tempus IC™ Patient Monitor (K082718)) for FDA 510(k) premarket notification. This means the manufacturer is asserting their new device is as safe and effective as a device already on the market, rather than conducting a de novo study against pre-defined acceptance criteria for a novel device.

However, I can extract the relevant information and present what is available in a structured manner, highlighting the limitations.

Here's the breakdown of the information requested, based on the provided text:

Acceptance Criteria and Device Performance Study for Sonicaid FM800

Based on the provided FDA 510(k) summary for the Sonicaid FM800, the device aims to demonstrate substantial equivalence to predicate devices rather than meeting specific, explicitly stated acceptance criteria from a de novo study. Therefore, the "acceptance criteria" are implied by the performance of the predicate devices. The study conducted to support this is primarily comparative bench testing and reliance on OEM-provided clinical data.

1. A table of acceptance criteria and the reported device performance

Since specific, quantitative acceptance criteria are not explicitly defined in the document for general device performance (like sensitivity/specificity for a diagnostic device), I will use the comparison to the predicate device's characteristics and the documented performance improvements as a proxy.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Test Set Sample Size:
  • For non-clinical bench testing: The document does not specify a "sample size" in terms of number of cases or patients for the comparative bench testing (document 7515101 - FM800E Comparative Bench Test Summary) or the MsP02 verification protocol (document 7514502), although these would involve laboratory tests on the device itself.
  • For clinical tests: "No specific clinical tests were carried out to determine substantial equivalence." The submission references clinical trials carried out by the OEM providers of the SpO2 technology, but the sample size for these external OEM trials is not provided within this document. User evaluation trials are proposed but not yet completed at the time of submission.
• Data Provenance:
  • Bench Testing: Conducted internally by Huntleigh Healthcare Ltd. (United Kingdom). This would be prospective for the submitted device, comparing it against the predicate.
  • OEM SpO2 Clinical Trials: Conducted by BCI (Smiths Medical). The country of origin and whether these were retrospective or prospective are not specified in this document.

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)

• The document does not mention using experts to establish ground truth for the test set as part of its own substantial equivalence testing. The primary test method was comparative bench testing against a predicate device.
• For the OEM SpO2 clinical trials, details about expert involvement for ground truth are not provided in this submission.

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

• No adjudication method is mentioned for any test set within this submission. The tests performed are primarily engineering bench tests or rely on external OEM clinical data.

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 MRMC study was done. This device is a medical monitor, not an AI-powered diagnostic imaging tool that would typically involve human readers. The document states that user evaluation trials are proposed to verify effectiveness in clinical situations, but these are not described as MRMC studies and were not completed at the time of submission.

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

• The device is a monitor that provides physiological parameters. Its performance is inherent in its measurement accuracy and display, which can be evaluated in a standalone manner (e.g., how accurately it measures heart rate or blood pressure compared to a reference). The "Comparative bench tests" confirm this standalone performance. No specific standalone performance metrics (e.g., algorithm only) as might be seen in an AI context are provided, but the device itself has standalone performance.

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

• For the bench tests, the "ground truth" is typically established by using calibrated reference equipment or standards to ensure the new device's readings are accurate and comparable to the predicate device.
• For the OEM SpO2 clinical trials, the type of ground truth for oxygen saturation would likely involve co-oximetry, the gold standard for blood oxygen measurement. However, this is not detailed in the provided text.

8. The sample size for the training set

• The device is a traditional medical monitor; it is not described as utilizing machine learning or artificial intelligence that would require a "training set" in the computational sense. The "improved signal processing" or "enhanced" algorithms refer to conventional digital signal processing, not AI model training. Therefore, this question is not applicable.

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

• This question is not applicable as there is no "training set" for an AI model mentioned for this device.

The Dolphin 2000 Oximetry Sensors are indicated for use in continuous monitoring of arterial oxygen saturation and pulse rate.

The Dolphin 2000 Oximetry Sensors are fully compatible disposable and re-usable replacement sensors for use with Nellcor pulse oximeter monitors. They represent a design change to the Dolphin 2000 BCI Compatible Sensors.

The disposable Dolphin 2000 Oximetry Sensors are constructed in a similar manner to predicate devices. The emitter and detector diodes are embedded in a laminate of tapes that is connected to the cable assembly. The sensors have an adhesive bandage backing that allows the sensor to be applied to the patient by wrapping it around a finger or toe (measurement site). Four sizes of disposable Dolphin 2000 Oximetry Sensors are available, which are indicated for use for adult, pediatric, infant and neonatal application sites. The Dolphin 2000 disposable sensors are provided non-sterile for single patient use.

The re-usable Dolphin 2000 Finger Clip Oximetry Sensor is an adult-sized clothespinstyle clip that is placed on the end of a finger. The finger clip sensor consists of the emitter and detector components mounted in opposing clip halves, maintained in mild compression by a spring hinge. The molded outer components house the optoelectric components within contoured pads that maintain contact with the patient's finger. Clear windows within these pads permit the optical energy to pass through the finger for the measurements. The Dolphin 2000 re-usable sensors are provided non-sterile.

The Dolphin 2000 Oximetry Sensors were validated in clinical testing to demonstrate their accuracy in measuring arterial oxygen saturation (SpO2).

Ask a specific question about this device

Sathlaster is intended for use an adjunct to traditional Pulse Oximetry, in which the caregiver observes instantaneous Pulse Oximetry values as displayed on a Pulse Oximeter's face. SatMaster produces graphs and statistics describing a patient's Pulse Oximerry data trends over relatively long periods of time, including those times when the caregiver is not directly observing the Pulse Oximeter's display.

SatMaster is the name of EMG Scientific's Computerized Pulse Oximetry Software product. This product consists of a Program Diskette, a Software License, a User Manual, and a Test Cable. Thus, SatMaster is a software-only "device," intended for use with an MS-DOS, PC-type computer provided by the end-user. Briefly, the SatMaster software provides a PC computer user the capability of transferring Pulse Oximetry data from a Pulse Oximeter, storing the data on the computer, displaying the data in various forms, annotating the data, calculating statistics, and printing the results.

The provided document is a 510(k) Summary for a software device called "SatMaster," a Computerized Pulse Oximetry Software. This type of document is submitted to the FDA to demonstrate substantial equivalence to a legally marketed predicate device, rather than to establish new safety and effectiveness through a clinical study with acceptance criteria.

Therefore, the document does NOT contain the following information:

• A table of acceptance criteria and reported device performance.
• Sample sizes used for a test set or data provenance for such a test set.
• Number of experts or their qualifications for establishing ground truth for a test set.
• Adjudication method for a test set.
• Results of a multi-reader multi-case (MRMC) comparative effectiveness study, or any effect size related to AI improvement.
• Details of a standalone (algorithm only) performance study.
• Type of ground truth used (e.g., pathology, outcomes data) for a test set.
• Sample size for a training set.
• How ground truth for a training set was established.

Analysis of the Provided Information:

The document focuses on demonstrating that SatMaster is substantially equivalent to a predicate device (Nellcor N-250 Pulse Oximeter, which is a combination of Nellcor N-200 Pulse Oximeter and Nellcor N-50 Powerbase).

Instead of clinical studies with acceptance criteria, the document provides:

1. Device Description and Intended Use: SatMaster is a software-only device that transfers, stores, displays, annotates, calculates statistics, and prints pulse oximetry data from approved pulse oximeters. It is intended as an accessory to enhance a caregiver's use of Pulse Oximeters, providing trends over long periods.
2. Comparison to Predicate Device:
   • Equivalence: SatMaster performs similar functions to the Nellcor N-50 Powerbase portion of the N-250, such as extracting data, displaying trend information, producing tabular lists, and generating histograms of SaO2 levels.
   • Differences: SatMaster is not a patient monitor, does not provide alarms or ECG/Pleth waveform output, does not power the oximeter, and provides additional reports and data-management functions not present in the predicate device.
3. Safety and Effectiveness Argument:
   • The document argues that SatMaster's use should have no impact on the safety of the Pulse Oximetry monitoring process because the Pulse Oximeter itself (an approved device) performs the primary monitoring, and SatMaster only processes the data after collection.
   • It states that SatMaster software has been "designed and extensively tested to insure the correctness and accuracy of SatMaster's data retrieval, data management, data storage, statistical calculations, and reports." However, no details about these tests (e.g., methodology, sample sizes, specific metrics, or acceptance criteria) are provided.
   • It claims enhancements in safety and effectiveness compared to the predicate device, such as requiring patient ID entry (reducing mix-up risk) and generating more extensive reports.
   • It cites published articles describing research performed using SatMaster by various researchers, implying its clinical value. This is anecdotal evidence of device utility rather than a formal study proving specific performance metrics against defined acceptance criteria.

In summary, to directly answer the request, the provided 510(k) summary does not contain the information typically found in a study demonstrating a device meets acceptance criteria. It relies on a demonstration of substantial equivalence to an existing device and general statements about testing and clinical utility, rather than specific performance metrics against established thresholds.
