1. Pulmonary Arterial Pressure

Key Concepts & Definitions

  • Pulmonary Arterial Pressure (PAP): The blood pressure within the pulmonary artery, reflecting the pressure exerted by the blood as it flows through the pulmonary circulation.
  • Significance of PAP: Elevated PAP indicates pulmonary hypertension or overload, while low PAP may suggest volume depletion or dehydration. It is a critical hemodynamic parameter for assessing pulmonary vascular status.
  • Measurement of PAP: Typically measured invasively via right heart catheterization, providing direct and accurate readings of pulmonary artery pressure. Non-invasive estimates can be obtained through echocardiography.
