Respiratory muscle fatigue

Respiratory muscle fatigue or respiratory muscle dysfunction is common in patients with chronic lung disease and ICU admissions. For a long time, the problem of respiratory muscle fatigue or failure has not been taken seriously. The timely detection and treatment of respiratory muscle fatigue can correct respiratory mechanics abnormalities, reduce respiratory work, improve oxygenation, and shorten the time of mechanical ventilation. Therefore, in recent years, evaluation of respiratory muscle function in critically ill patients has become one of the important contents of intensive care.
