pulmonary artery pressure (PAP)

Normal range: 15-30/5-13 (mean 10-18) mm Hg. Similar to right ventricular pressure. Clinical significance: - elevation associated with pulmonary hypertension Special laboratory: - echocardiogram estimates pulmonary artery pressure a) overestimates PA pressure by > 10 mm Hg (27%) b) underestimates PA pressure by > 10 mm Hg (25%) c) 1/3 of overestimates & most underestimates exceed 20 mm Hg - pulmonary artery catherization
