pulmonary artery pressure (PAP)

Diagnostic procedures

• echocardiogram estimates pulmonary artery pressure
  • overestimates PA pressure by > 10 mm Hg (27%)
  • underestimates PA pressure by > 10 mm Hg (25%)
  • 1/3 of overestimates & most underestimates exceed 20 mm Hg
• pulmonary artery catherization

Reference interval

15-30/5-13 (mean 10-18) mm Hg Similar to right ventricular pressure.

Clinical significance

• elevation associated with pulmonary hypertension

More general terms

• arterial pressure

Additional terms

• pulmonary artery occlusive pressure (PAoP); pulmonary capillary wedge pressure (PCWP)
• pulmonary hypertension; pulmonary arterial hypertension
• right ventricular pressure (RVP)
