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
I seem to be missing these 2cm pulses. I can see the detection pulses but not the others. Could you point out a specific one to me.
at 5:54:00 starts what I think are the 1 cm detection pulses and right after they end (with the apnea) are the 2cm "pulses" that I think are just the machine responding to the end of the inhale. I do not think that these are any kind of test "pulse" they are however low level repeated pressure variations. I am trying to figure out what the OP is feeling as "pulses" and correlating their comments to what is on the graph.
