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

The normal range for pulmonary artery occlusive pressure (PAOP), also referred to as pulmonary capillary wedge pressure (PCWP), is typically between 6 to 12 mmHg. This measurement reflects left atrial pressure and is an important parameter in assessing left heart function and fluid status in patients.

In clinical practice, a PAOP within this range indicates normal left ventricular filling pressures, which is crucial for maintaining adequate cardiac output and ensuring proper organ perfusion. Values lower than this range might suggest hypovolemia, while higher values could indicate left heart failure or fluid overload. This is why understanding the normal values of PAOP is fundamental for healthcare professionals in monitoring cardiac status and guiding treatment decisions.
