Acute CorPulmonale and ARDS Circulation Protection China Study China (ACPC)

The investigators established a national cohort of Chinese ARDS with Acute CorPulmonale to enable prospective observational studies. The goals are the following. First, morbidity and mortality rate of ARDS with ACP in the ICU across Chinese mainland. Second, forming the diagnostic ultrasound strategy of ARDS-ACP, namely TRIP procedures. And predictive value of diagnostic strategy for ACP or prognosis of ACP were calculated. Third, comparison of ventilator parameters for ACP and non-ACP or survivor and non-survisors, which reaveald that of inappropriate mechanical ventilation on circulation and prognosis. Screening for risk factors of ARDS with ACP.
