Current status and future of phenotypic research on acute respiratory distress syndrome
Acute respiratory distress syndrome(ARDS)is a kind of acute diffuse inflammatory lung injury induced by susceptible risk factors such as pneumonia,non-pulmonary infection,trauma,blood transfusion,burns,aspiration or shock.It has high morbidity and mortality.However,a large number of clinical studies on ARDS treatment have not been successful.One of the im-portant reasons is that ARDS is clinically and biologically heterogeneous.A single treatment approach does not improve the clinical prognosis of patients.However,dividing this heterogeneous syndrome into more homogeneous subgroups may lead to greater success in identifying effective treatments.This paper aims to discuss the current classification of ARDS phenotypes.It is to help clinicians better identify and understand the phenotypes of ARDS and further provide accurate individualized treatment to improve the prognosis of ARDS patients.
