The user interface for control of nebulization is provided via the ventilator display unit. The Aerogen Aeroneb Pro Nebulizer (K021175) is provided standard with the unit.

AI/ML Overview

This document is a 510(k) summary for the GE Datex-Ohmeda Engstrom Carestation, a continuous ventilator. The provided text does not contain information about acceptance criteria or a study proving the device meets acceptance criteria in the way medical device effectiveness studies for AI/software devices typically do.

Instead, this document focuses on demonstrating substantial equivalence to predicate devices and compliance with voluntary standards for medical electrical equipment.

Therefore, many of the requested sections (e.g., sample size for test set, number of experts, adjudication method, MRMC study, ground truth type and training set details) are not applicable or not provided in this type of regulatory submission for a physical medical device like a ventilator.

Here's a breakdown based on the information provided in the document:


1. Table of Acceptance Criteria and Reported Device Performance

This document does not present acceptance criteria in terms of specific performance metrics (like sensitivity, specificity, accuracy) or a comparative performance study against a defined benchmark. Instead, the "acceptance criteria" for a traditional device like this ventilator are implicitly met by:

  • Substantial Equivalence: The primary "acceptance" is that the device is substantially equivalent to legally marketed predicate devices.
  • Compliance with Voluntary Standards: The device's design and testing demonstrate compliance with recognized industry standards.

Study Proving Device Meets Acceptance Criteria:

The document states: "The GE Datex-Ohmeda Engström Carestation has been validated through rigorous testing that, in part, supports the compliance of GE Datex-Ohmeda Engström Carestation to the standards listed above."

This "rigorous testing" would likely include:

  • Bench testing: To verify technical specifications and performance against design requirements and standards (e.g., airflow accuracy, pressure control, alarm functionality).
  • Electrical safety and EMC testing: To comply with UL 2601, EN/IEC 60601-1, and EN/IEC 60601-1-2.
  • Software verification and validation: To ensure the microprocessor-based control system functions as intended.
  • Materials compatibility testing: For components in contact with gases or patients.

However, the specific details regarding the methodology, results, or quantitative metrics of these internal validation tests are not disclosed in this 510(k) summary. These details would be contained within the full 510(k) submission, which is not publicly available.


Due to the nature of this submission (a 510(k) for a physical ventilator, not an AI/software device), the following items are largely not applicable or not provided in this public summary:

2. Sample size used for the test set and the data provenance: Not applicable in the context of device performance claims made via standards compliance and substantial equivalence to predicate devices. Testing would involve engineering validation and verification, not a clinical "test set" in the sense of patient data for an algorithm.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for a ventilator's physical performance is primarily against engineering specifications and industry standards, not expert clinical interpretation of data.

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: Not applicable. This is for a physical ventilator, not an AI-assisted diagnostic or therapeutic tool for human readers.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This is for a physical ventilator.

7. The type of ground truth used: For a physical device, the "ground truth" would be established by:
* Engineering specifications and design requirements: Ventilator output (pressure, volume, flow) measured against intended values.
* Reference standards and calibrated equipment: For measuring performance parameters.
* Physiological models: For testing performance under simulated patient conditions.
* Clinical consensus on safety parameters: Ensuring the device operates within safe physiological ranges.

8. The sample size for the training set: Not applicable. This is not an AI/ML device that requires a training set.

9. How the ground truth for the training set was established: Not applicable.
