Obstructive respiratory diseases such as asthma or COPD are a common reason for emergency room visits. Currently, nasal gill capnography and oxygen saturation measurement (SpO2) are the only two non-invasive means of continuously monitoring a respiratory pathology. To date, Respiratory Functional Explorations (CFE) and more particularly spirometry, are considered as the reference examinations for the diagnosis or monitoring of asthma or COPD. However, physical and physical constraints make their use almost impossible in the context of the emergency with patients presenting to emergencies in respiratory distress, often require oxygen therapy or even non-invasive ventilation. Only pulmonary auscultation can make the diagnosis of acute decompensation of obstructive pathology. This technique is qualitative and imprecise, sometimes leading to a diagnostic uncertainty resulting in delay in taking charge and inappropriate therapy.
Studies have shown a change in the capnography curve in obstructive airway disorder and a strong correlation between some capnography parameters and spirometry parameters such as the Tiffeneau ratio (FEV1 / FVC), suggesting capnography as a simple and effective technique for the diagnosis of obstructive syndrome of patients in emergencies.
