The machines' algorithms have been changed since Dr. Michael Berthon-Jones of ResMed said that about ten years ago.avi123 wrote: A pressure of 16 is regarded as high. The higher the pressure,
the more central hypopneas you will have. At a
pressure somewhere around 10 cmH2O, the central
hypopneas become central apneas. On the other
hand, the vast majority of obstructive apneas are
already well controlled by 10 cmH2O, and we are
only fine tuning using snoring and flattening. So it
is a pretty good bet that if the pressure is already
above 10 cmH2O, any apneas are most likely
central, and you should leave them alone (except
in patients with central apneas due to heart failure).
But if the pressure is below 10 cmH2O, most
apneas will be obstructive and you should put the
pressure up. There’s nothing magical about 10
cmH2O, it’s just a good place to put the line in the
sand.
Thank you, but as Wulfman said, I started out at 10 and it wasn't controlling my apnea. I've settled on 16 after 6 months of slow tweaking to find out what worked for me. Advice much appreciated, but I've got it pretty well dialed in now.avi123 wrote:Try putting the machine on straight CPAP at 10 and check the results.sleepylynn wrote:Sorry for the late reply on this thread, folks - just want to say a big thank you to everyone!
Wulfman: You'll be happy to note I eventually settled at a fixed pressure. I'm now at 16, and my AHI is <1 every night. Snore numbers fluctuate a little, but that's mostly due to congestion issues (just started nightly nasal irrigation to try to straighten that out).
I'm doing CPAP entirely on my own, and I don't know what I would have done without forums like this one and the generous advice shared. THANK YOU.
