Question: 1 / 630

Changes in the Pulmonary Capillary Wedge Pressure (PCWP) indicate problems with which part of the heart?

The right ventricle

The left ventricle

The Pulmonary Capillary Wedge Pressure (PCWP) is a measurement that reflects the pressure in the left atrium and, indirectly, the functioning of the left ventricle. When the left ventricle is not functioning adequately, whether due to conditions like heart failure or valvular disease, the pressure increases in the left atrium and consequently in the pulmonary capillaries. This increased pressure can lead to pulmonary congestion and other complications as blood backs up into the pulmonary circulation.

Measuring PCWP allows healthcare providers to assess left heart function effectively. An elevation in this pressure is typically indicative of left-sided heart issues, providing vital information for diagnosis and treatment plans. By understanding that changes in PCWP are primarily related to left ventricular performance, it becomes clear why this measure is critical in evaluating conditions that affect the left side of the heart.
