After using if for an hour or so i will remove it in the night unknowingly sometimes. So times i feel suffocatied and remove it.
Can you clarify what you mean by feeling suffocated?
People use the phrase, "I feel suffocated" to mean one of two very different things, and which thing you mean by "I feel suffocated" is extremely important in figuring out what to do about the problem.
So when you say you feel suffocated, which do you mean:
You can't seem to inhale enough air through the mask to be comfortable---i.e it feels like there's just not enough air coming through the mask to breath comfortably.
You can't seem to exhale enough air to feel comfortable enough to take a good, full inhalation---i.e. it feels as though there is too much air coming through the mask for you to breathe comfortably.
If the problem is "I can't inhale comfortably" then it's probably being caused by a ramp that starts out at too low of a pressure and lasts for too long of a time OR it could just be that your (minimum) pressure setting is simply too low. Eliminating the ramp, or increasing the ramp's beginning pressure, or increasing the (minimum) pressure setting are all things that might help.
If the problem is "I can't exhale comfortably" then eliminating the ramp, or increasing the ramp's beginning pressure, or increasing the (minimum) pressure setting are probably NOT going to fix the problem. If the problem is "I can't exhale comfortably", you need to look at the exhalation relief settings. While you would think that increasing the EPR or Flex setting would help the most, for a few people, a lower EPR or Flex setting provides more comfortable exhalation relief than the highest setting does. If the problem "I can't exhale comfortably" is severe enough and playing with the EPR/Flex setting doesn't fix the problem, it's worth asking the sleep doc if a very modest decrease in pressure could be used at least temporarily.
