There is no right or wrong. Just whatever works for you, everyone is different ... some swear by it while others swear at it
I turned EPR off some times ago and never looked back, affect my breathing pattern and feel like rushing me to breathe but of course one mans meat is someone else poison

This suggests to me that either the machine is faulty or I would be better using it in CPAP mode with a higher pressure setting to prevent the apnea in the first place. I used to use CPAP mode in S9 Escape using EPR 3 but it occurs to me that by the same token the lower pressure on expiration increases the the risk of onset of an apnea because it has less of a prophylactic effect. Feedback would be appreciated before I return the Resmed Machine under complaint. Incidentally, the S9 Escape would abruptly reduce noise and output (Detected by touch) but still show the correct pressure on the screen. Pointless to test it because when the machine is stopped and started again it is normal. Any similar problems?

No auto CPAP/APAP machine will increase the pressure rapidly. It's usually something like 1 or 2 cmH20 pressure points per minute. If you're breathing normally and suddenly transition into apneas, it will take the machine a while to catch up, and you may suffer from apnea for a while.

This is one reason why it's important to set the minimum pressure to a high enough level that it stops most of your apneas.

Some of the more complicated machines like ASV (Adaptive Servo Ventilators) or "T-mode" bilevel machines DO try to respond more quickly, but many people find them hard to sleep with because they feel like they're forcing you to breathe on the machine's terms, not yours. You can usually get better results with a properly adjusted APAP or CPAP.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
