Sleep Apnea Treatment

I have a co worker who is the same age with the same diagnosis. We were diagnosed in the same year, so we assume we have had the disease for about the same amount of time. We both have the C-Pap. He is not on oxygen during the day. I am on oxygen therapy 24/7.

He has been a smoker. He had pneumonia last year , and it seems his disease has begun progressing much more rapidly than mine. He has been hospitalized, and needed a respirator twice in the last six months.

Is this a usual sequence for this condition?

As to the statistics on the Scoliosis I would like to know how that would apply to botht he hereditary forms and conditional or accidental forms of Scoliosis.

How many people currently live in the USA today?

Ty in advance!

Ok so I am an obesed man 292lbs 6ft3 and age 25, I have obstructive sleep apnea. I am wondering if I have hypertension as well or not or if I am borderlined hypertension. so here it goes:
My average blood pressure reading is 140/90 occasionaly I will experience nausea and throw up an average of maybe 4 days in a month, as well as once in a while I will have heartburn. I have heartburn generally 2xs a month. The last time I had my blood tested my bad chloestral was about 20 points too high.
Last year my granpa died of natural causes in his sleep (his heart stopped beating and he had some heart issues durin his life).
So do you think I might have hypertension? also my dr. never said I had it or not. so he recomended me to go on a diet, so I started weight watchers when I was 301.4 lbs and now I weigh today at 292.4.
any advice? and also I am in the process of quitting smoking.
