Technical Feasibility Study of a Novel Wearable Capnograph (MARIE) in an Emergency Care Environment, Part 1

MARIE will be connected to the patient by attaching the nasal adapter set and connecting the CO2 sensor. ETCO2 and RR values will be logged before and during the transport by writing down the values in the Case Report Form (CRF). On arrival at the hospital ETCO2 and RR will be measured by a reference instrument and logged in to the CRF. There will be trained study personnel responsible for operating the investigational device and populating the CRF, capturing all information which is required according to the study protocol.
