Puff Puff Puff on the A10 When Asleep? Is ET Calling??

the respironics do create 'puffs' which are 1 second long pressure increases every few seconds, to check the response (much as you described above).

resmed machines don't puff... they vibrate the air pressure at 4hz, starting 6 seconds after you stop breathing... sometimes you can feel it, sometimes not, you can see it on the mask pressure line, and to a lesser extent, then flow line.
