What is wedge pressure?
A measurement that reflects the pressure in the superior vena cava
A measurement that reflects the pressure in both the aortas
A measurement that reflects the pressure in the right atrium
A measurement that reflects left ventricular end-diastolic pressure
The Correct Answer is D
A. Superior vena cava pressure reflects right atrial pressure, not wedge pressure.
B. The aorta has its own pressures, unrelated to wedge pressure.
C. Right atrial pressure is measured separately, not via wedge pressure.
D. Pulmonary artery wedge pressure (PAWP) reflects the pressure in the left atrium and indirectly estimates left ventricular end-diastolic pressure, indicating left heart preload.
