CVS Practice Test

The normal pulmonary capillary wedge pressure (PCWP), also known as pulmonary artery occlusion pressure (PAOP), typically ranges from 2 to 15 mmHg. This measurement is crucial in the assessment of left atrial pressure and is commonly used in clinical settings to evaluate heart function and fluid balance.

Understanding the significance of this range provides insight into cardiovascular health. A PCWP within this range indicates that the left heart is functioning properly and that there is an appropriate volume status without significant congestion. Values that are significantly lower than this range may suggest hypovolemia, while significantly higher values could indicate left ventricular failure or fluid overload.

This helps in distinguishing between different cardiovascular conditions and guides appropriate treatment interventions. Recognizing the normal limits of PCWP allows healthcare professionals to interpret the readings accurately in their clinical assessments.
