Abstract:

Excessive respiratory drive and effort is associated with lung and diaphragm injury, thus respiratory drive and effort monitoring during mechanical ventilation is especially important. In clinical practice, diaphragm electrical activity and airway occlusion pressure are used to monitor respiratory drive, esophageal pressure and expiratory occlusion are used to monitor respiratory effort. Clinically, appropriate respiratory and effort can be achieved with lung and diaphragm protective ventilation strategy by regulating respiratory support level, adjusting sedative dosages and degree of neuromuscular blockade as to prevent ventilator-induced lung and diaphragm injury.

Key words: Respiratory drive, Respiratory effort, Lung protective ventilation strategy, Ventilator-induced lung injury
