Abstract

Respiratory muscle fatigue is caused by excessive effort, relative to the strength and endurance of the respiratory muscles. It can be manifested by reductions in respiratory drive (central fatigue), by impaired neuromuscular transmission (transmission fatigue), by decreased contractility (contractile fatigue), or by a combination of these factors. Respiratory muscle fatigue probably contributes to the difficulties some patients encounter when being weaned from mechanical ventilation, to the symptoms of exercise intolerance and dyspnea in chronic lung disease, and to carbon dioxide retention. Therapy depends upon a reduction in the required level of respiratory effort and/or an improvement in respiratory muscle strength and endurance.
