Hi I just started using a Resmed S8 APAP for a couple of nights. Settings: Autoset. Pressure is set to Min of 6 and Max of 12.
I would appreciate any help with the many questions I have :-)
a. what does the Pressure reading on "Efficacy Data" mean ? I saw 9th percentile on the FAQ. And I saw 95th percentile on other websites.
b. I like to understand the difference between the pressure reading on "Efficacy data" and "Smart data". Why are they different ? Today, Efficacy Data reads 10 and Smart data indicated 7.8
c. When awake, the pressure goes up to as high as 10 in some instances. I do not expect the pressure to go up since I'm awake. Is this ok ? This makes me wonder if APAP works for me or not.
d. Sleep lab test indicated a setting of 7 for my pressure. However, my Efficacy data has been reading between 9 and 10 for the last couple of nights. AI has been between 2 and 3. Again, I wonder if APAP is for me or not.
I would appreciate any info. Many thanks.

I know that many of us do not use the ramp feature once we are used to treatment.
Some nights I fall asleep rather quickly, others I am awake for awhile. So are there any benefits Rock to really using the ramp due to this? Can a person set their ramp for their starting pressure? I use an apap with a setting of 9 to 15. Could I set the ramp at 9?

Check your Users Manual, SleepyCarol, I believe the Ramp starting pressure can be set as high as 10 cms. (Going from memory here). Are you comfortable starting at 9 cms of pressure? (I'm pretty sure the same holds true for Settling).

Yes, but if are doing well without it I would not worry about it. one or 2 onset events is not going to change your data all that much. I would say that if you can't fall asleep within a ten minute period consistantly this might be a feature for you.

Hold on there. Settling is not the same thing as ramp. Settling overrides the Autoset Algorithm so that the device sits at the minimum prescribed pressure for the duration of the settling time. Since the AutoSet Algorithm evaluates one's breathing on a breath-by-breath basis, and since our breathing naturally slows down when we are initially relaxing and trying to fall asleep, one can easily experience a pressure increase while still awake if the Settling feature is turned off.
Rock is correct that the settling time should be set to approximate the amount of time it takes to fall asleep. If your minimum pressure is significantly less than your titrated pressure, and you find that when you look at the data that you are having a cluster of events at the beginning of the night, you should first reduce your settling time. If that doesn't do the trick, talk to your doctor about increasing the minimum pressure, so that you will have more effective treatment if you are asleep while it is still in settling mode.

Thank you, Daniel! Its been so long since I used my AutoSet Vantage I couldn't remember if it had Ramp or Settling in auto mode.

Okay. I start out with 9 and am fine with that. I have found that a low pressure will cause me to become apprehensive as I feel as though I can't breathe.
I have an M series apap.

Thank you Daniel I stand corrected. i also want to say that my comments were more for Narciso's case.If you currently do not have any problems falling asleep please do not make any changes to your machine.
