Impact of Dyspnea, Regional Lung Ventilation, and Diaphragmatic Function During de Novo Acute Respiratory Failure

NCT04961437 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 55

No results posted yet for this study

Summary

Modern management of acute respiratory failure aims to relieve dyspnea and anxiety by providing a non-invasive respiratory support. This approach tries to avoid endotracheal intubation, patient self inflicted lung injuries (PSILI) and diaphragmatic dysfunction. The present study aims to evaluate dyspnea, pulmonary regional ventilation and diaphragmatic function in patients with hypoxemic acute respiratory failure by different observations, and to bring risk factor for intubation out.

Conditions

  • Acute Respiratory Failure

Interventions

OTHER

Diaphragmatic ultrasound and electrical impedance tomography

A diaphragmatic ultrasound in a half sitting position. The diaphragmatic excursion and the thickening fraction of the right hemi-diaphragm will be measured. \- Acquisition of 10 minutes of regional pulmonary ventilation by electrical impedance tomography.
