It's not that hard to learn how to get into the secret "technician-only" settings screens on existing CPAP machines. They can't be that dangerous. I've fiddled with mine (the technician told me how) and the worst I've done is give myself an uncomfortable night's sleep. It's an airhose with a not-particularly-strong seal gently squirting air into your nose, not a chest tube.
