The study will be conducted in the emergency departments of Grenoble and Lyon University Hospitals.
Patients will be recruited by the dispatch nurse at the emergency department reception according to the inclusion and non-inclusion criteria. The EtCO2 will be measured at the emergency reception during assessment of vital signs by the same nurse with the help of a mask or oxygen glasses measuring EtCO2. The patient will then be treated conventionally according to current international recommendations. The physician in charge of the patient will be blinded to this measurement. Once the patient is discharged from the emergency department, the primary and secondary endpoints will be collected by a clinical research associate 24 hours after admission from medical record.
