The use of the OmniCap™ capnometer is indicated to provide measurement and monitoring of carbon dioxide concentration of the expired breath and respiration rate of adult patients. It is an adjunct in patient assessment, to be used in conjunction with other methods to determine clinical signs and symptoms by or on the order of a qualified healthcare provider.

Environment of Use: Hospitals, Sub-acute care facilities and intra-hospital transport.

The OmniCap system incorporates three parts:

• . OmniCap monitor
• . Sensor cartridge with a colorimetric litmus media
• AC power adapter .

The OmniCap monitor houses the electronics including the color sensor, a LED light source, a miniature vacuum pump, internal sample gas tubing, a rechargeable nickel metal hydride battery pack, and the user interface.

The OmniCap Sensor cartridge is a colorimetric litmus media sealed in a plastic cartridge with clear windows on each side.

The AC power adapter is IEC 60601-1 compliant. The AC power adapter converts supplied AC power to DC power to facilitate charging the battery.

The OmniCap unit can operate with or without the AC adapter connected and powered.

Here's a breakdown of the acceptance criteria and study information for the OmniCap device, based on the provided text:

Acceptance Criteria and Device Performance

Study Information

The document describes non-clinical bench testing to demonstrate performance and substantial equivalence.

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

   • The document does not explicitly state the specific sample sizes (e.g., number of test points, number of sensor cartridges) used for each individual test. It broadly mentions "various concentrations of CO2" and "the sensor cartridges."
   • Data Provenance: Not specified, but implied to be laboratory bench testing conducted by Respirion, Inc. (the manufacturer). No information on country of origin for data. The study is retrospective as it involves testing of the manufactured device.

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

   • Not applicable. The ground truth for the bench tests would have been established using reference gas mixtures with known CO2 concentrations and controlled respiration rates, not through expert opinions.

3. Adjudication method for the test set:

   • Not applicable, as ground truth was established by calibrated reference equipment/methods, not by human adjudication.

4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

   • No, an MRMC study was not done. The document refers to "Comparative performance to the predicate - IR technology" but this is described as bench testing at various concentrations and respiration rates, not a multi-reader study.

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

   • Yes, the primary performance evaluation described is a standalone (algorithm only) bench test. The device's sensor detects color change and converts it to a numerical value, which is then assessed against known reference values. There is no human involved in interpreting the color change for the subject device's reported performance, unlike the reference device (Maxtec FloCap) where a user visually interprets color.

6. The type of ground truth used:

   • Reference gas mixtures with known CO2 concentrations and controlled respiration rates generated by test equipment. This falls under a form of "reference standard" based on calibrated instrumentation and scientific principles.

7. The sample size for the training set:

   • Not applicable. This is a non-AI/ML device. The device's technology uses a pre-set colorimetric system with a sensor, not a machine learning algorithm that requires a training set.

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

   • Not applicable, as there is no training set for this device.
