Intended Use
The CoSense ETCO Monitor is indicated for the monitoring of carbon monoxide from endogenous sources (including hemolysis) and exogenous sources (including CO poisoning and smoke inhalation) in exhaled breath. The end tidal carbon monoxide level can be used for the monitoring of carbon monoxide in medical conditions in which the rate of hemolysis may be relevant. It is also for use in smoking cessation programs and can be used for the screening of CO poisoning and smoke inhalation.
Device Story
CoSense ETCO Monitor is a portable, battery-operated device for measuring end-tidal carbon monoxide (ETCO) concentration. It utilizes an infrared capnometer to identify the end-tidal portion of a patient's breath and an electrochemical sensor to quantify CO concentration. The device is operated by healthcare professionals in clinical settings. Input consists of a single breath sample collected via a disposable nasal cannula. The device processes this input to provide a quantitative CO measurement, which is displayed on an LCD screen. The output assists clinicians in assessing CO levels related to hemolysis, smoke inhalation, or CO poisoning, thereby informing clinical management and diagnostic decisions. The device features a software-controlled menu for patient identification and monitoring parameters.
Clinical Evidence
No new clinical trials were conducted. Evidence consists of an analysis of published clinical data regarding the use of FDA-cleared CO monitoring devices for screening CO poisoning, smoke inhalation, and hemolysis detection. Results demonstrate that the CoSense device's functional and performance specifications are consistent with those of devices used in the cited studies, specifically the CO-STAT End Tidal Breath Analyzer, and fall within established clinical ranges for accuracy and resolution.
Technological Characteristics
Portable monitor; electrochemical CO sensor; infrared capnometer for breath detection. Powered by rechargeable Li-Ion battery. Patient interface: non-DEHP PVC nasal cannula. Dimensions: 246mm x 197mm x 68mm; Weight: 3.3lbs. Connectivity: standalone with LCD interface. Software: microprocessor-based with menu-driven control. Performance: 1.0-25.0 ppm range, 0.1 ppm resolution, <5 min measurement time.
Indications for Use
Indicated for monitoring endogenous (e.g., hemolysis) and exogenous (e.g., CO poisoning, smoke inhalation) carbon monoxide in exhaled breath. Used for smoking cessation programs and screening for CO poisoning/smoke inhalation. Applicable to patients where hemolysis rate monitoring is clinically relevant.
Regulatory Classification
Identification
A carbon monoxide gas analyzer is a device intended to measure the concentration of carbon monoxide in a gas mixture to aid in determining the patient's ventilatory status. The device may use techniques such as infrared absorption or gas chromatography.

## Non-clinical Performance The design and performance specifications are identical Data: to our predicate device. No additional non-clinical performance data is provided. Clinical Performance An analysis of published clinical data was conducted. Data: This analysis was performed on the uses of other FDA-cleared CO monitoring devices for measurement of CO in screening of CO poisoning, smoke inhalation and detection of hemolysis. Results provide objective evidence that the functional and performance specifications of CoSense device are similar to the devices in the published studies, specifically the CO-STAT End Tidal Breath Analyzer, and are within the range of accuracy, measurement, and resolution of the devices currently used clinically for detection of endogenous and exogenous sources of elevated CO. Conclusion: Capnia considers the revised CoSense ETCO Monitor device to be equivalent to our predicate device and the reference predicate listed above. This conclusion is based upon the devices' similarities in indications for use and identical principles of operation, technology, and performance. The accuracy, measurement range, and resolution specifications are unchanged from our predicate CoSense device. These performance specifications are similar to the CO-STAT End Tidal Breath Analyzer (reference predicate). The proposed CoSense device indication is also similar to the indication for CO-STAT End Tidal Breath Analyzer, as both indications use hemolysis as examples of endogenous CO. Published clinical data and previous design verification data demonstrate that the device is equivalent to our predicate device.
