Respiratory Therapist/Pulmonary Hypertension


Just had a right heat cath. and diagnosed with pulmonary Hypertension. Are there groups or stages for the pressure.I have a reading of 49 when the RHC was done. Would this be Moderate or High?

In PH, usually the hemodynamic number we are looking at is the PAP, or the Pulmonary Artery Pressure. It refers to the pressure in the pulmonary artery (the vessels that take blood through the lungs). Like with the blood pressure measurement on your arm (systemic blood pressure) there is the top number (systolic) and the bottom number (diastolic). The "normal" pressures in the lungs are about 25/8. 25 is the systolic PAP.  These pressures can only be measured by floating a catheter in the vessels (right heart cathetertization), which obviously you have already had done. IF it is definitely your Systolic PAP that is 49, I would certainly say that is "High" and cause for concern.

What did your doctor say about this 49, in terms of its level of seriousness and how he proposes to treat it?
