Thanks everyone for replying and I'm very interested in the effect the pressure setting has on light headiness. Mine is set at 6 to start but as I've said I'm fairly sure that it is an auto pressure machine. At times through the night I seem to have trouble getting enough air so I briefly have to take a few breaths with my mouth. I usually only take a few breaths and then resume breathing through my nose. I can briefly set my machine to 10 to test the fit of my mask, it goes back to 6 after 5 minutes. The airflow always feels better to me at 10 and I was thinking of getting the pressure increased, next time I see my DME vendor. But now I'm a bit worried about increasing it, if it adds to my light headiness which seems logical to me. My pressure was originally at 4 which felt too low to me to get enough air flow to breath.
I was off the machine for about 3 months due to the negative effect it had on me. But I just felt my sleep apena getting worse. So recently I've been back on it probably for about a month now and I'm having the same problems with light headiness and irritability when I use it. I sometimes feel my fatigue is worse when I use it. It's very discouraging especially when the DME vendor is next to useless with help, when I ask them about it. I'm amazed by the number of people at work who have stopped using their CPAP machines due to their frustration with using the machines and seeing little effect from them. I think a big part of it is the lack of good instruction from the DME vendor. Who in my opinion, as I've said earlier, are more interested in selling the machines than giving effective help to their customers.
I am also a bit mad at my GP for suggesting a take home test rather than visiting an actual sleep doctor. The sleep doc was only 25 dollars more expensive and obviously would've had more knowledge about my condition. At the moment funds are a bit tight so going to see a sleep doc are on hold for now.
ElleMarie my AHI pre CPAP was 17.6 and as low as 1.6 after CPAP. Those figures are almost a year old. I don't have any recent data. I'm going to see my DME vendor soon and will get some updates. The 1.6 seems good but doesn't really matter if I feel horrible every time I use it.
Just started using it again after being off it for about 3 months. Been using it for a month again off and on due to the adverse conditions I experience when using it. I feel very tired, fatigued when I don't use it. Occasionally when I use it I feel a bit rested but that's the exception not the rule. Most of the time it's light headed, fatigue and irritable.
I think I do have a " data capable machine ". But usually I just insert the data card and give it to DME vendor, who accesses the information. Not sure why i went right to a auto machine or did the take home test. It was what my GP, Ear, Nose and Throat doctor the DME vendor advised. Their the experts so one tends to listen to them, should've researched it more before I got it.
I'm on this form to learn more as I feel these "experts" aren't giving me the info I need.
