What is the normal range for pulmonary artery occlusion pressure (PAOP)?

The normal range for pulmonary artery occlusion pressure (PAOP), also known as pulmonary wedge pressure, is considered to be between 6-12 mmHg. This measurement is critical as it reflects left atrial pressure, which helps in assessing left heart function and fluid status in patients, particularly those with respiratory and cardiac conditions.

Values below this range might indicate hypovolemia, while values above it can suggest conditions such as heart failure or fluid overload. Understanding the normal range for PAOP is vital for clinicians in critical care settings, as it aids in diagnosis and management decisions regarding patient fluid management and therapy.

PAOP is measured via a catheter placed in the pulmonary artery and requires accurate interpretation to guide treatment effectively. This range provides a standard reference for normal cardiovascular dynamics, ensuring that health care providers can make informed decisions based on patient-specific hemodynamics.
