The tests performed to diagnose you will allow your doctor to determine which type of PH you have and the severity of your illness. They will consider factors such as your functional class (a classification based on how PH impacts your everyday life), the pressures in your lungs, and how well your heart is functioning to determine which treatment is best suited to your needs. Your medical team will work with you to establish a personalized treatment plan and adjust it as your symptoms and lung pressures change.
