Hmm, sounds to me like you need a new doctor pronto! You also probably need to be on O2 24/7 right now. Of course I am not a doctor. What were your pulmonary pressures? The only real way to diagnose PH is through a right heart cath as echoes are only estimated pressures and can be way way off. However, I would not ignore the PH either. You need, in my opinion, to go find a PH specialist as soon as possible. Have you had pulmonary function testing yet? Of course the low O2 levels can make the pulmonary pressures go up. Also, I think your O2 provider can set up another concentrator so you could have one on both floors of your house. Please get a new pulmonologist right away.
