Diaphragm Response in Elderly for Acute Monitoring
Starting soon
Conditions studied: Acute Dyspnea, Acute Respiratory Failure, Diaphragmatic Ultrasound
In brief
Acute dyspnea is a common cause of emergency department admissions among elderly patients. Acute respiratory failure is often multifactorial and requires rapid and reliable evaluation. Currently, management relies on clinical, biological, and radiological assessments, but diaphragmatic ultrasound could provide an additional tool for real-time respiratory function evaluation. This study aims to integrate this non-invasive technology into the initial assessment of patients to improve care pathways. Hypothesis : Diaphragmatic ultrasound enables reliable assessment of respiratory function and can predict the need for mechanical ventilation.
