Central Sleep apnea

[d2forbes]

Hi I have been diagnosed with Central Sleep Apneas and use a Bipap AutoSV Advanced system One. My problem is the response to a central episode. My machine gives gradual puffs of air which couldn't knock a fly off a leaf (first 3 or so ) and it does increase those breaths, but by then I'm starving for air. Then repeat the above sequence over 8 hours. I have about 30 episodes per hour without the machine. I'm wondering how the machine thinks my lung capacity is so low. I wake up sucking air thru my mask holes to compensate each time. I'm about 50% better with this machine set up, but still really tired each day. Any comments are appreciated !

G'day d2forbes, welcome to the forum.

Your machine has a wealth of adjustments which should be able to kill those apneas much more quickly than you describe. Unfortunately I don't know sufficient details about the PRS machines, but I'm sure some of the other members here will be able to help.

Good luck!

Hi d2forbes,

Hang in there for more answers to your question and much success to you with your CPAP therapy.

I am rather new to my ASV machine, but my first question(s) are can you tell us what each/all of your settings are at?

You can set machine max
EPAP MIN
EPAP MAX
PS MIN
PS MAX
BACKUP RATE (BRM) = AUTO, or a number

For those main settings (just using myself for an example):
MACHINE MAX=25
EPAP MIN=13.5
EPAP MAX=18
PS MIN=4
PS MAX=10
BRM=auto

Now, without using software you can't figure out easily how to adjust your settings. Did a Doc give you a script with settings?

Others will jump in shortly with more info, but I suspect that either your starting settings are too low, or, your caps (MAX) is set too low.
