when your oxygen rate goes below 88...you need to buy an oximeter and then you can test yourself. Good luck.

JenkG, I don't know the difference between lung capacity and blood oxygen. My blood oxygen upon exertion goes as low as 80%. After
two or three minutes of resting it returns to 91-97%. My pul. dr. says
that I have 40-60% of lung capacity of what is was before diagnosis.
I have no energy after exercising or working and need a long rest of
at least an hour before doing anything. It seems like all my muscles
turn to lead and it requires a great effort to get around. I use oxygen when I am going to work outside or play tennis (doubles only). I take a mult. vitamin to help keep my blood iron up. Hope this helps and will send more info if you want.

JenkG,My doctor says I am doing okay,but still use oxygen during walking or trying to do house work,I do get tired and fell weak.I also wear the oxygen at all times during the night.I don't let My oxygen drop below 88.You should talk to Your doctor about this.
