AI/ML Overview

The provided 510(k) summary for the Puritan Bennett Sandman Duo and Sandman Duo ST does not describe a study involving a test set, expert readers, or ground truth in the way typically associated with AI/ML device evaluations. This document pertains to a medical device from 2008, well before the widespread use of AI in medical image analysis or diagnostics, and focuses on demonstrating substantial equivalence to predicate devices through performance testing, not clinical effectiveness studies with explicit acceptance criteria related to a specific medical condition's diagnosis or treatment outcome.

Therefore, many of the requested categories cannot be directly addressed from the provided text. The submission describes functional performance testing against regulatory standards and existing predicate devices.

However, based on the information provided, here's a breakdown of what can be extracted:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Demonstrated Equivalency)Reported Device Performance and Compliance
Functional Performance Specifications: Capable of meeting stated performance specifications for CPAP and Bilevel modes (3-20 cmH2O CPAP, 3-25 cmH2O IPAP, 3-20 cmH2O EPAP) in spontaneously breathing patients over 30kg for Obstructive Sleep Apnea."Functional testing confirms that the Sandman Duo ST are capable of meeting its stated performance specifications. The device passed all tests."
Compliance with Regulatory Guidance: Adherence to the November 1993 draft "Reviewer Guidance for Premarket Notification Submissions" (Division of Cardiovascular, Respiratory, and Neurological Devices)."Testing confirms that the Sandman Duo and Sandman Duo ST comply with the November 1993 draft 'Reviewer Guidance for Premarket Notification Submissions' published by the Division of Cardiovascular, Respiratory, and Neurological Devices. The device passed all tests."

The Sandman Duo and Sandman Duo ST had been found compliant and had been certified to the standards referenced in the 'FDA Reviewer Guidance for Premarket Notifications'."
Equivalence to Predicate Devices: Performance is equivalent to Puritan Bennett Sandman Intro (K071575), Sandman Info (K080439), GoodKnight 425 (K041819), and GoodKnight 425 ST (K050072) for relevant modes/features."The Sandman Duo and Sandman Duo ST are equivalent to the Puritan Bennett Sandman Intro (K071575) for all aspects except the Bilevel mode, to the Puritan Bennett Sandman Info (K080439) only for detection of apneas and hypopneas, the Puritan Bennett GoodKnight 425 (K041819) for the Bilevel mode. The Sandman Duo ST is equivalent to the Puritan Bennett GoodKnight 425 ST (K050072) for the Bilevel mode including optional backup frequency." This is a statement of the conclusion of the equivalency assessment rather than specific performance details.

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

  • Sample Size: Not applicable. The submission describes laboratory performance testing (e.g., electrical safety, mechanical, software verification), not a clinical study with a patient test set as would be relevant for AI/ML performance evaluation.
  • Data Provenance: Not applicable. The document refers to engineering and software validation, not clinical data from patients.

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

  • Not applicable. There was no clinical test set requiring expert ground truth for this type of device submission.

4. Adjudication method for the test set:

  • Not applicable.

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. This is not an AI/ML device; it's a non-continuous ventilator/CPAP device.

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

  • Not applicable. This device is a hardware medical device with embedded control software, not a standalone algorithm. Its "standalone" performance would refer to its physical operation and pressure delivery, which was tested.

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

  • Not applicable in the context of clinical "ground truth" for diagnostic or treatment efficacy. The "ground truth" for the engineering performance tests would be defined by the specifications of the device and the requirements of the standards (e.g., a pressure reading must be within X tolerance of the set pressure).

8. The sample size for the training set:

  • Not applicable. This device does not use machine learning that would require a "training set."

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

  • Not applicable.
