What this Trial Is About

Although we know that these numbers are underestimated, Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease that affects between 8 and 12% of adults. According to a 2020 WHO report, it is the third most common cause of mortality in developed countries. This disease is punctuated by exacerbations associated with an 8% mortality of hospitalized patients, increased to 24% when the patient is admitted to intensive care unit. Early detection and treatment of these exacerbations appears to be essential to improve patient survival. End-tidal carbon dioxide (EtCO2) is used to assess a patient's respiratory and hemodynamic status. Indeed, EtCO2 is a non-invasive measure that could allow the estimation of arterial carbon dioxide (PaCO2) without performing blood gases, an arterial blood sampling, classically at the radial artery. This study aimed to find an EtCO2 value which at the time of the initial management, would be predictive of a severe COPD exacerbation, as well as PaCO2.
