Abstract
Acute respiratory failure is one of the most distressing situations for the patient. Emergency cases do not always present in conditions that are ideal for immediate diagnosis, which sometimes compromises outcome.
Radiological examination is a crucial tool in the care of the critically ill. It serves to diagnose and to monitor a variety of cardiopulmonary disorders but each technique as plain x ray chest and CT chest has its drawbacks
Ultrasonography became a valuable tool in the management of critically ill patients. Its safety and portability allow for use at the bedside to provide rapid, detailed information regarding the cardiovascular system and the function and anatomy of certain internal organs as respiratory system
The aim of our study was to assess the relevance of lung ultrasouographic examination as an immediate and non invasive technique in the diagnosis of the underlying etiology of acute respiratory failure due to respiratory diseases and compare it to the currently used diagnostic tools in the respiratory critical care practice in the intensive care units.
This study included 100 patients admitted to the ICU with acute respiratory failure. Acute respiratory failure was defined based on the classical clinical and biological criteria for admission to the ICU.
Patients with non respiratory causes of acute respiratory failure, rare causes of respiratory failure or multiple final diagnoses at the end of hospitalization were excluded from the study.
