Summary

The goal of this Prospective interventional multicenter diagnostic study is to investigate the use of diaphragmatic ultrasound (DE) as a diagnostic tool in an adult emergency department for patients in acute respiratory distress.

The main question it aims to answer is to evaluate the relevance of measuring the Sum of Plateau Times (SPT) by Clinical Ultrasound in Emergency Medicine (CHEM) for the diagnosis of pneumopathy during acute respiratory distress (ARD) in the Emergency Department.

Secondary objectives include the study of other diaphragmatic ultrasound parameters, inspiratory plateau time (IPT) and expiratory plateau time (EPT), and the diagnostic relevance of PTS for the diagnosis of decompensation of Chronic obstructive pulmonary disease (BPCO) and acute cardiogenic pulmonary edema (APO).

Each eligible patient will have a right diaphragmatic ultrasound performed by a trained physician, then clinicobiological data will be collected later from medical records, and the etiological diagnosis will be established by a committee of 2 experts in the management of respiratory distress.

Interventions

DIAGNOSTIC_TEST

diaphragmatic ultrasound

The examination is performed with a phased array probe, also known as a cardiac probe. The technique used will be that described and validated in anterior studies: the patient is in the Fowler position: half-seated, at an angle of around 45 degrees. The patient is ventilating spontaneously, and no participation is required. The probe is positioned in the sub-costal region between the mid-clavicular and anterior axillary line on the right, and between the anterior and middle axillary line in the sub- or intercostal region on the left. The liver is used as an acoustic window for the right hemi-diaphragm. The probe is oriented medially, cranially and dorsally. The operator switches to time-motion (TM) mode when an angle of over 70° is achieved between the upper part of the diaphragm and the analysis axis in the most cephalic part of the diaphragm. The image is frozen when 6 respiratory cycles have been measured.
