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

Pulmonary capillary wedge pressure (PCWP) is an important hemodynamic measurement used to assess left atrial pressure and, indirectly, left ventricular performance. A normal PCWP range is typically between 6 and 12 mmHg. This range indicates adequate preload on the left side of the heart and helps to differentiate various cardiovascular conditions, especially in patients presenting with dyspnea or pulmonary congestion.

PCWP values below this range may suggest hypovolemia or low cardiac output, while values above this range can indicate left heart failure, fluid overload, or pulmonary edema. The ability to accurately interpret these values is crucial for effective diagnosis and management in an acute care setting. Hence, awareness of the normal range is essential for clinical decision-making regarding fluid management and treatment strategies in patients with cardiovascular issues.
