For the diagnosis of pulmonary artery StrictionBP hypertension you must know one thing that there are always two associated conditions with this problem. They are namely Pulmonary artery occlusion pressure (PAOP) that should be less than 15 mm Hg (2000 Pa) and pulmonary vascular resistance (PVR) which must be greater than 3 Wood units (240 dyn•s•cm-5 or 2.4 mN•s•cm-5). If these two conditions are found to as mentioned above then you are a pulmonary hypertension patient.

Echocardiography can be used to estimate the pressure of the pulmonary artery but there is a more definite assessment with the Swan-Ganz catheter. This is because the PAOP and PVR cannot be measured directly with echocardiography. Thus the diagnosis of PAH requires a right-sided cardiac catheterization. This procedure uses a Swan-Ganz catheter that can also measure the cardiac output, which is a far more important tool in measuring disease severity than the pulmonary arterial pressure.

As the Normal pulmonary arterial pressure has a mean value of 12-16 mm Hg (1600-2100 Pa) and that too in a person at sea level. But if you have Pulmonary hypertension your mean pulmonary artery pressure will exceeds 25 mm Hg (3300 Pa) at rest or 30 mm Hg (4000 Pa) with exercise.Often reported on the echocardiogram reports Mean pulmonary artery pressure (mPAP) is generally confused with the systolic pulmonary artery pressure (sPAP). So when you get your echocardiogram report you should be aware of it. A systolic pressure of 40 mm Hg typically implies a mean pressure more than 25 mm Hg that is roughly, mPAP = 0.61•sPAP + 2. So don' forget to check these out in your reports.
