How to Evaluate the Pulmonary Valve and Right Ventricular Outflow Tract in Prone Position during Invasive Mechanical Ventilation

Abstract

In the COVID-19 pandemic, we performed a series of echocardiograms using subcostal views. After placing a patient in a prone position during invasive mechanical ventilation, the echocardiogram transducer was placed under the patient in the left subcostal position. This performance allowed us to evaluate the function of the pulmonary valve and estimate pulmonary pressure. This is a complement to the monitoring with a transthoracic echocardiogram in the prone position.
