RE: It this normal?
Hi All,
Per vsheline request I'm posting the five minute period where I think the pulsing occurs.. One more thing I may add the pulsing is not constant but it increase in intensity and frequency as well.
As for sleeping.. My preference is to sleep on either side or on my belly. I haven't been able to sleep on my back in looong time because I snore really bad and my mouth dries up instantly..
@ PoolQ
"If you lie still you can feel the pulsing.."
Yes, as long as don't inhale.
The pulsing stops the moment I inhale..
It maybe machines way to keep me breathing, if so then this is not for me. So far I can honestly say I have consistently sleep lot better with nasal strips..
Tried to attach the newest SH report as mentioned early but can't do to size limit. Is there a way to remove prior attachments from early posts by me? Thanks.

RE: It this normal?
Thank you for quick explanation.
Hope it will shed some light on this..
RE: It this normal?
okay I had to go back in my sleephead data to when I had the same machine as you have. My plots look exactly like yours. Those "pulses" happen when I inhale and the pressure goes up when I have reached my peak inhale flow and then the flow drops back down to zero before I exhale. You also show the "detection" pulses during your apneas, these are 1 cm pulses used to detect that an apnea is obstructive or central. The inhale/exhale pulses are only 2cm pulses at change-over.
Are you sure you are feeling these? Most people will not be able to feel this level of pulsing.
One of the problems with being new to CPAP is that this is like an alien sitting on our face blowing air up our nose, this is nothing like we have ever felt before and have no words to really describe what it feels like.
Lets let others chime in and see what they say

That's exactly what I'm feeling, I think.. My breathing pattern slows down allot when I'm in deep sleep and relaxed. After exhaling, right before inhale, the pulsing starts. I can induce and feel the pulsing when purposefully hold my breath. All different brand machines behave the same way?
Just quick note. Increased the upper pressure as suggested and nothing changed as far as I can tell except for my mask broke seal..
RE: It this normal?
The "detection" pulses are 1 cm-water amplitude; and 4 Hertz in frequency. They do not start until breathing has stopped for 4 seconds. ResMed calls this their FOT algorithm which is to detect they type of apnea by "listening" with the flow sensor. It would be unusual to feel the FOT pulses; but not impossible.
