What is the normal range for pulmonary artery wedge pressure (PAWP)?

The normal range for pulmonary artery wedge pressure (PAWP) is typically considered to be between 8-12 mmHg. This measurement is an important parameter in evaluating left atrial pressure and assessing a patient's fluid status and cardiac function. A PAWP within this range suggests that left ventricular filling pressures are normal, which is crucial for effective cardiac output and organ perfusion. Abnormal PAWP levels can indicate various pathophysiological conditions, such as heart failure or fluid overload, making it a valuable tool in the monitoring and management of critically ill patients. Understanding this normal range helps healthcare providers interpret the results accurately and make informed decisions regarding patient care.
