RE: All day dyspnea, have had jaw surgery and a trach to "fix" it. Looking for a bipap
I'm not certain what ventilator you are using.  Your machine is set as follows:
aPCV mode: Auto Pressure Control Ventilation (generates the preset pressure during a preset inspiratory time at the preset respiratory rate. The pressure is constant during the inspiratory time and the flow is decelerating.)
IPAP: Inhale positive air pressure, set at 18.5 cm
EPAP: Expiratory positive air pressure a.k.a. PEEP Positive End Expiratory Pressure.  Set at 4.0 cm.
IPAP-EPAP = Pressure Support (PS). Your pressure support for each breath is 14.5 cm-H2O
Backup Rate: The number breaths per minute (BPM).  With a setting of 15 BPM your machine is acting as a ventilator and does not rely on your spontaneous breathing effort. With a backup rate of 15 BPM each breath cycle is 4-seconds long.
Insp. Duration: a.k.a. inspiratory time set at 1.5 seconds. So you have 1.5 seconds to inhale and 2.5 seconds to exhale.
Inspiratory Trigger: I'm not sure.
Exp. Level: I'm not sure
Insp. Sens.: Probably the sensitivity to your spontaneous inspiratory effort, but this machine is not programmed for spontaneous respiration.
TV.V. Switch: Tidal volume on. The machine detects your tidal volume and automatically uses additional pressure support up to the Max IPAP of 30 cm to maintain the target vent.
TV.V.  This is the tidal volume target in milliliters
Max IPAP: the maximum inspiratory positive air pressure available in auto PCV mode is 30 cm
Min IPAP: the minimum inspiratory positive air pressure to be used in auto PCV mode is 20 cm (I suspect this over-rides the IPAP setting earlier in the settings).

This is a very complex machine that basically does your breathing for you. There are aspects to its operation I am not familiar with, and any changes should be by your doctor, not me.

That would be my take as well. This is some sort of NIV/ventilator set to breathe for you. Unless you know what you're doing on adjustments, I'd advise against it. Check with doc or the RT/respiratory therapist if you need settings adjusted.
