Shortness of breath is extremely common with
PH. Rest when needed and talk to your Dr.

I am on supplemental O2. I don’t normally need when I am in my home, but if I am moving around a lot I do. As discussed, speak with your Dr.

Hi Ann, My oxygen level drops to low 90's when doing housework with heart rate going higer than like 130, but if I sit down and rest my numbers go back to normal, I tend to recover very fast. I was put on oxygen for exercise since my levels would drop to high 80's and low 90's when I would work out, I first got put on 2 Liters when I exercise and when I sleep at night, last month we had to move it to 3 Liters to get the same results. If I sit down and rest I do recover pretty quickly. When i got put on oxygen i didn't feel so exhausted after my exercise. Mine is due to interstitial lung disease, pulmonary fibrosis and now mild PH.

Ann, that sounds like a good idea. I use oxygen at night as well. Last winter I went through a few days where I felt SOB all the time. My saturation levels without oxygen were good. I used the oxygen for several days 24/7. It made a difference. It's still a mystery why I was so SOB, but the doctor said, "You've got the oxygen, use it." Oxygen is a vasodilator, helping to open all the tiny blood vessels in your lungs. With PAH it is not unusual to need oxygen with activity but not at rest.
