I’m getting a ResMed AirCurve VAuto.
Currently using a ResMed 10 APAP with a minimum of 18 cmH2O and EPR of 3... still have flat inspiratory curves according to Oscar, and apneas and hypopneas. Any higher and I suffer from aerophagia.
Any tips for the BiPAP? I’m assuming IPAP will have to be at least 18.

With EPR at 3 your EPAP is 15
I have a pressure of 18 breathing in (inspiratory), and of 15 breathing out (expiratory). Right? So IPAP would be 18 and EPAP would be 15? Or am I totally getting this wrong.
You're correct. I made a typo
Thank you.
Review the ResMed Sleep Lab Titration Guide at https://www.resmed.com/us/dam/documents/products/titration/s9-vpap-tx/user-guide/1013904_Sleep_Lab_Titration_Guide_amer_eng.pdf.
If you follow the principles there it should get you started.
In VAuto mode: EPAP 15, Pressure Support of 3 will start you at IPAP of 18. Both will increase throughout the night in response to events, but always 3 cm apart.
EPAP of 13 with Pressure Support of 5 will also get you IPAP of 18, but it will be easier to exhale. Feel free to experiment.
If you want to run in full manual fixed mode, set mode to S. But if you do, the VAuto will not record flow limit data.
Further, I prefer trigger: high and cycle: medium. Trigger is how fast it responds to your natural inhale, and cycle is how long that breath lasts.
It’s a great machine. Enjoy!
Awesome, thank you!!
Dr. Krakow mentions that most of his patients are on PS 5-6, with his own being at an 8. What has your experience been?
PS of 5 made all the difference in the world for me. Currently in S mode, 6 and 11. It’s glorious.
I sleep better with fixed pressure.
Thanks!
Where did you find this?

"Should you be able to produce the same results with CFLEX, APAP, etc? Presumably so, except for one 'large' difference. You cannot generate the same gradient or gap between IPAP and EPAP with any of the other devices. And, in our clinical and research experience, we are using gaps of 4 to 12 cm of water in our patients. My personal bilevel settings are 21/12.5 for a gap of 8.5."
Great, thanks!
Do you know how the V Auto compares to the Dreamstation Bi-PAP for treatment of UARS? Is one clearly better than the other?
Unclear, I can only speak for the VAuto
I always find it interesting how people fail to notice that it's not only easier to exhale, but to inhale as well (That takes care of the RERAs). PS decreases work of breathing.
No, it's the proportion of inhalation flow rate to peak inhalation flow rate that signals the transition to EPAP.
That sounds about right.
