BIPAP ST users

[sistergetu]

just wanting to meet others using BIPAP ST. I'm finding it a difficult transition from cpap, which I wrote about on CPAP thread. Basically feeling like my settings are not right since I feel the machine rushes me to breathe

Bump, and here is your description of the problem from the other thread:

struggling with new BIPAP ST. I feel like the machine is rushing me to breathe and not synched to my natural breathing. Feels very stressful, like I need to take off the mask and rest. Also, I can tell the pressure after ramp is too high, causing me to gulp the air. I know I need an adjustment, but don't yet know the terms. Am i needing increased rise time or timed Insp? or something else altogether.
IPA 20
EPAP 16
Rate: 14
Timed Insp 1.2 secs
Rise Time: 3

BTW, it's usually best to start your own thread and not glom onto an old thread.

Caveat: I'm not a BiPap S/T user but coming to this from an ASV point of view.

Here is a description of a couple of parameters from the Providers Manual that may be related to how the machine feels.

BPM (BPM) - If you are in S/T mode, you can set the Breaths Per Minute setting from 0-30 in 1.0 BPM increments. The default is 10.

Ti - If you are in S/T mode, you can set the Inspiratory Time setting from 0.5 to 3 seconds in 0.1 increments. The default setting is 1.0.

BPM may be set to a too fast rate. What is yours set to?
On an ASV machine, setting this parameter to high makes it seem as if the machine is driving your breathing.
