high pressure

[SarcasticDave94]

There is Smart Start/Stop but it seems to not be as smart as advertised, sometimes stopping if it doesn't sense airflow for a set number of seconds. Some had suffered from unintentional stop and restart actions.

Just my opinion, but address what causes your PAP feeling the need for your high pressure periods and it won't make you feel like you need to turn it off then back on.

Here is last night's data.  reduced max to 14 and min to 8 but changed min to 7 because it was more tolerable.  Another restless night's sleep, but for what it's worth, my AHI is low

[SarcasticDave94]

From 02:20-02:40 a cluster of Apnea events probably ruined that session. From there, 5 sleep sessions that total 3 hours 58 minutes probably isn't helping gaining a well rested state.

that cluster is validating the "chin-tucking, consider the soft cervical collar, see the link in my signature for a deeper dive and examples.

try a max of 12
Also consider dropping the ramp.

Sorry if I'm being dim, but is it ever appropriate for the machine to deliver high pressure when you're awake?

I accept that high pressure will sometimes be required when I'm asleep.

Since I know the machine can't really tell when I'm awake, what I want is a big, red "reset" button on top, that immediately sets the pressure back to minimum. I know from looking at OSCAR that it will be back up again soon enough -- when I'm actually asleep. Fiddling for the little on/off switch in the dark and freezing cold is a bit of a drag.

Of course, if there's a good reason to deliver high pressure when you're actually awake, what I'm asking for makes no sense.

I ordered a Releaf collar last week and should have it by Fri.  I turned on ramp because I was having trouble falling asleep last night and did not need the distraction of more air noise.  With min at 5 or 6 it does not bother me too much but 7 or 8 it is more noticable

[quiescence at last]

if you still want the ramp in there, try setting it just below your normal minimum. Since you switched back to 7, it looks like you purposely set the ramp on. I would set the ramp start at 6.0 and see if you still feel as comfortable. I am guessing that you feel more comfortable due to EPR of 0 at ramp starting at 4.0, not because 8 is too high. But the idea here is to reduce your snoring as quickly as possible so you can drop off to sleep quicker. I am guessing 6.0 for ramp start will significantly reduce the snores at start.

I am in favor of reducing the max pressure to 14, and even 13 or 12 to meet the "normal" conditions that started to reappear once the machine settled down (see about at 02:52 on Jan 4 chart). The maximum is just meant to be low enough that you don't get jerked awake by the heightened pressure. You will eventually get used to slightly higher pressures and the awakening will not occur.

Let's keep adjusting the start pressures and head position to reduce the random periods of snore and severe flow limitations and monitor results with Oscar charts.

No, you're not being dim.

The machine can't really tell if you're awake or asleep. It can guesstimate it using autoramp but for me, it always kicked in almost immediately so I just gave up with it.

If the pressure is rising while you're awake, then it's sensing something to cause it to rise - usually that would be flow limits but it could be unintentional breathing gaps that look like apneas to the machine, because it can't tell if you're holding your breath deliberately or actually asleep and obstructed/having a central apnea. So it's just going to react according to it's algorithm.

It depends how awake you were. If you were fully awake, it'd be interesting to see that section of chart on your thread, but if you were in that half awake, half drowsy state, then it's probably just that as your brain and body get ready for sleep. 


The big red button you ask for is, I'm afraid, the on/of button. If it's any help, practice at finding it with your eyes closed makes it pretty easy to find eventually (as long as it's within reach).

Yeah. With all the other things I'm currently worried about, I won't increase my stress level any further by obsession about having to press a button twice, rather than once.

addressing positional chin tucking (and the flow limitation & oa that results) will likely help keep high pressure at bay. otherwise, the way to deal with too-frequent runaway pressure is to restrict max pressure. if that results in other problems like increased oa, one has to either find a satisfactorily happy medium or move to a more capable modality (bilevel, for example).
