What is the normal pulmonary capillary wedge pressure (PCWP) range in mmHg?

The normal pulmonary capillary wedge pressure (PCWP) range is between 6-12 mmHg. This measurement is used to estimate left atrial pressure and can provide important information about a patient's fluid status and cardiac function. It is particularly useful in assessing conditions like heart failure, where elevated PCWP can indicate increased left atrial pressure due to fluid overload.

A lower range of 4-8 mmHg is not typical for a healthy individual, as it suggests potential underfilling of the left atrium. Similarly, values above 12 mmHg may indicate increased pressure, often related to pulmonary congestion or fluid overload conditions. By understanding that the normal range falls between 6-12 mmHg, healthcare providers can better interpret the significance of the PCWP in clinical practice, tailoring management strategies to the patient's needs.
