Maximal inspiratory pressures and vital capacities are measurements of neuromuscular respiratory function and predict diaphragmatic strength. Maximal expiratory pressures also reflect abdominal muscle strength. Frequent evaluations of these parameters should be performed at bedside to monitor respiratory status and the need for ventilatory assistance.
