New user problem
#1
I am only 3 weeks into using a BiPAP machine and I am perplexed. I am being awakened after about 3 hours by not being able to get enough air through the mask (an Easy Life nasal). It feels like the machine is throttling back and I have to consciously breathe in to get any air. I thought it was the machine and had it replaced after a week, and last night was the first on my third one and it does the same thing. Even my afternoon naps end up the same. After 2 ½ or 3 hours I am wakened by not getting enough air. Anybody have any insight on this?

Thanks
Clint

Get fitted for a new mask ASAP! Avoid restricting oxygen!

I don't believe it is the mask causing the problem. When I first put it on and turn on the machine it is fine. If does not leak, is not too tight and I am able to go to sleep without any difficulties. The problem starts after I have been asleep for 2 to 3 hours. The 'force' of the air seems much less even though the machine is still showing 13" & 9" on inhale and exhale.

This is not a mask issue. If it were, he would be experiencing it much earlier.

Clint, try an experiment the next time you have a day off or 2-3 hrs free. Put on the mask, turn on the machine, and wear it. At the 2-3 or so hour mark it usually does it, see if it does it again.

Have you tried to remove the mask, breathe for a few breaths, then put it back on? If so, does the lack of air feeling continue?

Have you also tried to turn off the machine, wait a few seconds, then turn it back on again?

And, lastly, do you use the ramp feature?

Thank you for that confirmation.

I wear the mask when I take a nap, usually daily (I am retired) and the same thing happens at the same interval of 2 to 3 hours.

No, but I will.

I did this when it first happened and it did not make a difference. I had hoped that the machine would reset and start back as it did when I first went to bed, but it didn't.

No - I assumed that the Ramp button would reduce the output and I felt I needed to increase the output.

I am not sure the problem is not a lack of oxygen and my body wanting more air to compensate. I will try the "take the mask off for a while" trick tonight and see if that works. Hopefully I can get back to sleep after it happens.

Thanks,
Clint

Clint, do you have the Bi-Flex feature turned on? I think the factory default is a Bi-Flex setting of 2. It can be set higher to 3, lower to 1, or turned off altogether.

All this feature is supposed to do is reduce the pressure when you exhale (even further than the reduction you get on a BiPAP when switch from inhale to exhale). It also attempts to modify the shape of the pressure curve, so if you are inhaling very very slowly it will interpret that as an exhale (go figure) and drop the pressure.

Try turning the Bi-Flex feature off. I have the older model 750 but if yours is like mine you'll need to get into the clinician's manual to make the change.

Edit: Correction. I have the older model 650P.

Clint KY, I am truly puzzled. It is not uncommon for a new user to feel they are not getting enough air, but your pressures are high enough that I wouldn't expect that to be the problem.. How are you feeling during the day? Can you check your AHI? I think it's time for a doctors input now. Good luck, keep us posted. Thanks for answering questions put to you. That's the only way anyone can help you.

Now try the mask while awake. If the same thing happens, then it is not something in your sleep that you do nightly (or nap-ly). Like reach REM sleep that far in or whatever.

If this machine is data capable, it would be interesting for you to see the data and see just what is happening prior to you waking up.

And, like Zimlich says, might be time to talk to the doc.

Actually much better than before getting the machine.

1 Day: 2.5
7 Day: 3.2
That is since Tuesday (two days ago) as the tech took the data off the card when I got the new machine.
I know the number reflects how well I sleep but do not know the significance of value.

I have a call for an appointment with my Repertory Therapist at Holland Medical now. I am hoping it does not take a trip to my Sleep Doctor as I can not understand a word he says.
