Apr 21, 2025Class IIOpen, Classified
Sampling set nasal cannula used with End-Tidal Carbon Monoxide (ETCO) monitor may have residual carbon monoxide and volatile organic compounds present due to insufficient aeration of the cannula's carbon filter prior to sealing, which may lead to higher than expected ETOCc scores during clinical evaluations.

Device type (GMDN): Carbon monoxide breath analyser

An electronic device intended to be used in a clinical setting to measure the concentration of carbon monoxide (CO) in a gas-mixture sample, exhaled by a patient, using a particular method (e.g., electrochemical, infrared spectroscopy, gas chromatography). It may be used to aid in determining the patient's ventilatory status (typically the lung diffusing capacity), or for determining exhaled CO levels (e.g., during jaundice screening in newborns, or in smoking cessation programs); it may also have the capacity to measure the concentration of CO in the atmosphere.
