[Research advances on the mechanisms and prevention and treatment of patient self-inflicted lung injury].

Researches have shown that lung injury due to excessive spontaneous breathing effort, that is, patient self-inflicted lung injury (P-SILI), may be the important manifestation and possible mechanism of ventilation-associated lung injury and ventilation-induced diaphragmatic dysfunction in acute respiratory distress syndrome (ARDS) patients who were mechanically ventilated with intense spontaneous breathing. This paper reviews the concept of P-SILI, possible occurrence mechanism, clinical significance, and prevention and treatment, in order to provide more ideas for clinical ARDS management.
