Cardiopulmonary Ultrasound for Acute Lung Injury Patients

Abstract Background: Point of care ultrasound was used to evaluate critically ill patients, with emphasis on cardiopulmonary function assessment, so as to guide clinical decision-making and optimize the perioperative management plan. Two patients with hypoxemia were examined by bedside ultrasound. One patient had massive transfusion-related lung injury and the other had sepsis related lung injury. Combined lung and cardiac ultrasound in evaluation of 2 critically ill patients as blood transfusion and pulmonary edema was found.Case presentation: Acute gastrointestinal hemorrhage with shock. Hypoxemia occurred after massive transfusion, and bedside cardiopulmonary ultrasonography confirmed pulmonary edema for first case. In the second case, coronary artery bypass graft was performed with a great saphenous vein incision, which did not heal after surgery. Great saphenous vein incision debridement was performed in emergency presented with sepsis. Cardiopulmonary ultrasound revealed left heart dysfunction and hypoxemia associated with pulmonary edema.Conclution: At the bedside, cardiopulmonary ultrasound in critically ill patient is a useful tool for diagnosing pulmonary edema.
