Diaphragm-Protective Mechanical Ventilation: Saving the Diaphragm from the Detrimental Effects of Mechanical Ventilation

Diaphragm weakness develops in up to 80% of the critically ill patients, and is associated with adverse clinical outcomes. Mechanical ventilation has been proposed to play a role in the development of diaphragm weakness in critically ill patients, especially by ventilator under-assist or ventilator over-assist. Therefore, in addition to the concept of lung-protective ventilation to protect the lung, diaphragm-protective ventilation has been recently proposed to limit the development of diaphragm weakness. In this concise review, we will discuss the current evidence for diaphragm-protective ventilation and the clinical consequences.
