My brother was diagnosed with sleep apnea 5 yeas ago and it would appear my time has just arrived.
My brother has a mild to moderate case and after trying the Fischer Paycal Icon for 4 years he bought a better one from ResMed S9 as it has the best back up by batteries; very important as he lives in the countryside where power failures are annual events.
It's a mazing how many around you tell you they or relatives have sleep apnea and how their lives have improved after starting to use it. One person uses it occasionally and has trouble as he has a beards making fit difficult, duh. It will take a couple of weeks to get us to it, but after that you won't feel right not using it, kind of like seat belts. the masks are a personal thing and can take some trial and error.
Modern machines are nearly silent once placed on the face and any partner who may be put off by it presence, when the urge hits, need to grow up. They can make a choice, a little initial inconvenience or a stroke out partner hobbling around or bed ridden.
It is a hard condition to diagnose as many people just slough off their bad sleep and constant fatigue as just getting old, until they notice their BP's spiking or worse, a stroke.
OHIP is changing its coverage each year, cutting back to where it's almost a joke now, but it's a no brainer; spending $1000-$1500 every 4 or 5 year for a machine, plus filter and new masks and tubes ( if really needed) is peanuts, compared to get really sick or worse. I know people who spend that every few months for medications just to live better.
