1. Had my first sleep study. 5/15/15
2 had my 2nd sleep study last night with cpap machine. Therepist said he had my my pressure at 16.
3. A friend gave me her cpap machine (she refused to use it after she got it a year ago, it is paid for)
4. Machine has an sd card in it set to 12 that my friends provider set for her.
5. I'm wanting to use the cpap machine this weekend (I cant get in to see the product provider til next week)
6. Can I change the settings to 16 myself? How
7. Would it still benefit me to use the 12 setting if I cant adjust it?
