Respironics DS950HS Pressure creep??

Respironics DS950HS Pressure creep??

Is this normal?? I have my ASV Respironics DS950HS EPAP min Set for 6.5CM, BUT as I inhale the readout shows it jumping to 8CM…and dropping back to 6.5 for my exhale…

And I was trying to fall asleep and things seem a little off and I checked the readout and now it was running a 10CM??

It seemed to have creeped up on the EPAP Min Setting.

Also:

It was going so high it was blowing my mask seal open, and I checked the display and it was reading 18-19-20CM and over 18CM my mask leaked and it seem better to keep the mask seal..so I set EPAPMAX at 18CM

What's your ramp on? If you've got a ramp on your machine is going to slowly increase until it reaches the pressure you're set at.
If your machine is set to start off as an EPAP is set on 6.5, when you exhale it should say 6.5.

Can you post any data so we can help you further?

Thanks, I think I got the answer:

This is completely normal for an ASV machine. All bi-level machines boost the pressure when we inhale. And the ASV models will sometimes boost IPAP even more than normal Bi-level machines do. We gradually get used to it. But it takes time.

Also, when we are falling asleep it is not unusual to have some low-level snoring or central events, so the pressure will boost itself up. If it is bothersome just turn off machine for a couple seconds and pressure will re-start at low level.

Yup. A bi level machine delivers two pressures: an inspiratory pressure ("IPAP") and an expiratory pressure ("EPAP"). The IPAP is always higher.

Good luck

I understood that BUT having it do other things like jump up a couple of CMs from what was set and to work its self up from 6.5 to 10CM was looking a little odd.

Thus this thread.

But it seems all is well and system is AOK.

Thanks.
