I was in the hospital for pneumonia and while I was getting a nebulizer treatment the therapist asked if I use a Cpap at home, at the time I didn’t have one. Now mind you I was only sleeping for 2 hrs a night during my pneumonia bout (2 weeks) and the therapist asked if I were open to using a BPAP (what they call it in a hospital) it was a large machine and I said of course. Upon using it I still only slept for 2 hours but it was a very restful 2 hours of sleep and was welcomed. I told my Pulmonologist and got set up for a sleep study, and it is all history. I sleep more restful (have much less visits to the bathroom at night) and use it religiously. Medicare covered my testing and machine. After my test my doc told me I stopped breathing x amount of times a minute, and was restless (tossed and turned) an ungodly amount of time during my test. On the follow up test (with the Cpap) the number decreased significantly. My sister snores like a constant thunder storm and she went for a test and got her Cpap, and now she doesn’t snore at all and tells me she sleeps much better.
There are two ways to use the machine, with a nostril mask (so to speak) and a full mask (you usually see on TV movies). The latter is what I use, I couldn’t get use to the nostril application, and if you were to catch a cold, I don’t know how well it would work, but I use the mask never the less. Hope this helps, and do read the instructions about your machine.
