Left atrial filling pressure closely approximates with ?
High-Yield Explanation
The pulmonary wedge pressure or PWP, or cross-sectional pressure (also called the pulmonary aerial wedge pressure or PAWP, pulmonary capillary wedge pressure or PCWP, pulmonary venous wedge pressure or PVWP, or pulmonary aery occlusion pressure or PAOP), is the pressure measured by wedging a pulmonary catheter with an inflated balloon into a small pulmonary aerial branch Because of the large compliance of the pulmonary circulation, it provides an indirect measure of the left atrial pressure Ref Harrison 20th edition pg 1456
