The anesthesia workstation Perseus is intended for use in anesthetizing adults, children, and neonates and can be used for automatic and manual ventilation, pressure-supported spontaneous breathing, and spontaneous breathing.

Perseus is equipped with airway monitoring, gas measurement and device monitoring, O2 insufflation, and an anesthetic gas receiving system.

Anesthesia is achieved through a mixture of pure oxygen and Air (medical compressed air) or pure oxygen and nitrous oxide, with the addition of volatile anesthetic agents.

AI/ML Overview

The provided document is a 510(k) premarket notification for the Dräger Perseus A500 anesthesia machine. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing detailed clinical study results often found for novel devices or AI/ML-driven diagnostics.

Therefore, the document does not contain the detailed information requested regarding specific acceptance criteria for performance metrics (like sensitivity, specificity, accuracy), nor does it describe a study explicitly designed to "prove the device meets the acceptance criteria" in the way one would for a diagnostic or AI algorithm.

Instead, the submission demonstrates compliance with recognized safety, performance, and electromagnetic compatibility standards, and states that the device's functionality and performance are substantially equivalent to its predicate devices.

Here's an attempt to answer the questions based on the available information, noting where information is not present:

Acceptance Criteria and Study for Dräger Perseus A500 Anesthesia Machine

The Dräger Perseus A500 anesthesia machine is a Class II medical device, and its 510(k) submission (K133886) focuses on demonstrating substantial equivalence to predicate devices and compliance with relevant industry standards for safety and performance. This is a different regulatory pathway than for novel diagnostic devices, especially those utilizing AI, which would typically involve detailed performance metrics like sensitivity, specificity, and ROC curves.

1. Table of Acceptance Criteria and Reported Device Performance

As this is an anesthesia machine and not a diagnostic device, the acceptance criteria are based on compliance with harmonized standards, functional equivalence to predicate devices, and safety. Quantitative performance metrics (e.g., sensitivity, specificity, accuracy) are not presented in this 510(k) summary in the way they would be for an AI model.

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

Not applicable in this context. The "test set" here refers to the device itself being tested against standards and its predicate, not a dataset for an algorithm. The evidence presented focuses on engineering verification and validation, and demonstrating equivalence. No specific "data provenance" related to a test set for an algorithm is mentioned.

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

Not applicable. This is not a study requiring expert-established ground truth for an AI algorithm. The "ground truth" for this device's performance is compliance with established engineering and medical device standards, and functional equivalence to legally marketed predicate devices.

4. Adjudication Method for the Test Set

Not applicable. There is no mention of an adjudication process for a test set in the context of this device.

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

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done, nor would it be expected for this type of device (anesthesia machine). This type of study is relevant for diagnostic devices where human readers interpret medical images or data, and the effect of AI assistance on their performance is being evaluated.

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

Not applicable. The Perseus A500 is an anesthesia machine, not a standalone algorithm. Its performance is inherent to its mechanical and electronic functions.

7. Type of Ground Truth Used

The "ground truth" for this submission is multifaceted:

Compliance with harmonized standards: The device's performance is measured against the requirements of international and national standards (e.g., IEC 60601 series, ISO 8835 series, ISO 21647, ISO 10993, ISO 15001, ISO 17664).
Engineering specifications: The device is verified and validated against its own design specifications.
Functional equivalence to predicate devices: The functionality, indications for use, and general performance are compared directly to previously cleared anesthesia machines.
Risk analysis: Hazard identification and mitigation are based on established risk management processes.
Usability evaluation: User feedback validates the intuitiveness and safety of operation.

8. Sample Size for the Training Set

Not applicable. The Perseus A500 is an anesthesia machine, not an AI/ML algorithm that requires a training set.

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

Not applicable, for the same reasons as #8.

Performance and testing:

Dräger installed and maintains an internal Quality Management (QM) System. The QM System describes the procedures for development related to medical devices and requires a particular development process with all related activities including risk management, verification, validation and documentation. This procedure is in accordance with the design controls as defined in the current "Good Manufacturing Practice" published by FDA.

Design controls procedures are implemented and maintained at Dräger. All product developments and changes to Dräger products follow this internal procedure laid down in internal standard operating procedures DMS IN4000 "Develop Product" and DMTN LM2310 "Execute Product Design Changes" respectively. The software has been verified and validated according to the specification and test requirements, and documented as described in the FDA Guidance for the Content of Premarket Submissions for Software.

The development of Perseus A500 was in accordance with these procedures and passed all verification activities. The risk management file identifies potential hazards and documents the result of the risk analysis including mitigation of hazards. Usability features have been evaluated by end-users and found that the Perseus A500 is safe and effective for use by the intended users, intended use, and use environment.
