Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The diaphragm is a fine striated muscle with both extra respiratory and respiratory functions. It does most of the breathing work in interaction with the accessory respiratory muscles, the rib cage and the abdomen. Its activity can be measured by the transdiaphragmatic pressure generated by the magnetic stimulation of phrenic nerves (gold standard). It has been shown in the literature that diaphragmatic ultrasound, via the measurement of diaphragmatic excursion and especially the thickening fraction, is an easily accessible, non-invasive, reproducible and relevant technique for evaluating acute diaphragmatic dysfunction in resuscitation patients.

The objective of this project is to evaluate the prevalence of diaphragmatic dysfunction at admission in patients hospitalized in intensive care / respiratory intensive care unit for hypercapnic and/or hypoxic acute respiratory distress and requiring ventilatory support by non-invasive ventilation or high flow oxygen therapy. A subgroup analysis will then be carried out on 3 populations:

* Hypercapnic exacerbation of chronic obstructive pulmonary disease
* Hypoxic acute respiratory distress on infectious lung disease
* Acute pulmonary edema
