Studies on intra-pulmonary gas distribution in the extremely obese. Influence of anaesthesia and artificial ventilation with and without positive end-expiratory pressure.

abstract：INTRODUCTION:Advanced life support (ALS) guidelines recommend ultrasound to identify reversible causes of cardiac arrest. Right ventricular (RV) dilatation during cardiac arrest is commonly interpreted as a sign of pulmonary embolism. The RV is thus a focus of clinical ultrasound examination. Importantly, in animal stu...
