[One case of VAV-ECMO treatment of a patient with severe cardiopulmonary insufficiency caused by inhalation of dilute nitric acid liquid and aerosol].

This article analyzed the use of veno-arterio-venous extracorporeal membrane oxygenation (VAV-ECMO) in the treatment of a patient with severe cardiopulmonary insufficiency caused by inhalation of dilute nitric acid liquid and aerosol. Combined with relevant literature, the pathogenesis was discussed and the treatment experience was summarized. The inhalation of a large amount of dilute nitric acid liquid and aerosol caused severe chemical pneumonia in the patient, which resulted in severe cardiac insufficiency due to the dysregulation of the ventricular artery coupling. After the administration of VAV-ECMO, the well-oxygenated blood was effectively supplied to the systemic circulation and pulmonary circulation, and the load of the heart was reduced, providing valuable time for the recovery of the patient's cardiopulmonary function.
