There are several types of PH that are diagnosed based on specific measurements and causes. The main way doctors determine your type of PH is through right heart catheterization, which measures your mean pulmonary artery pressure (mPAP) and other important values. It's important to ask your doctor specifically about your type of PH since different types may require different treatment approaches.

The main types include PAH (Group 1 PH) which is diagnosed when you have:
- mPAP of 20 mm Hg or higher
- PAOP measurement of 15 mm Hg or less
- PVR measurement greater than 2 Wood units
- No left heart or lung disease causing the PH Your symptoms and ability to perform daily activities also help classify the severity of your PH into four functional classes:
- Class 1: No symptoms at rest or during exercise
- Class 2: No symptoms at rest, but shortness of breath with daily activities
- Class 3: Major limitations with daily activities
- Class 4: Symptoms at rest and with any activity

It's recommended to discuss both your PH type and functional class with your doctor, as this helps guide treatment decisions. They can also advise you about monitoring your blood oxygen levels and when to seek immediate medical attention.
