A narrative review of driving pressure as a monitoring indicator during mechanical ventilation with spontaneous breathing.

The mortality of acute respiratory distress syndrome (ARDS) remains high, and mechanical ventilation (MV) is an essential means of treatment. During MV, people realize the benefits of spontaneous breathing and the disadvantages of uncontrolled spontaneous breathing. Current methods of monitoring spontaneous breathing include oesophageal manometry, P0.1, and diaphragm function monitoring. However, these methods have limitations and deficiencies. The driving pressure is a new indicator that reflects the strain of the lung, which indicates the volumetric injury of the lung and is independently associated with mortality in ARDS patients. Moreover, in recent studies, driving pressure monitoring has been shown to be feasible in assisted support ventilation. This review summarizes the current state of spontaneous breathing and examines whether it is convenient to monitor driving pressure during spontaneous breathing to achieve lung protection ventilation.
