No, absolutely not. The AutoSet is sooo much more capable.
ResMed AutoSet Dreamstation Auto comparison
Why ResMed?
1. Faster algorithmic response to events than PR.
2. ResMed Responds to Flow Limits
PR responds to Snores
3. Lower average pressure (PR require a higher pressure to ward off obstructive events)
4. Better to avoid Aerophagia.
5. EPR provides for better treatment of hypopneas, RERAs, Flow Limits, UARS, and snores
6. EPR acts like a BiLevel up to a limit of 3cmw (1,2, or 3cmw) and a max pressure of 20 cmw
7. EPR follows your breathing whereas Flex predicts it with a feeling of fighting to get a breath when it predicts incorrectly
8. More flexibility in treating a greater variety of Apneas and respiratory events.
9. In general provides better therapy.
I have frequently told many DreamStation users that they need to get either the ReaMed AutoSet or BiLevel to get better therapy.
Masks, read the Mask Primer in my signature. I use the ResMed P10 Pillow Masks and that is a very popular model here. The only issue may be mouth breathing but we will not know that until you try. There is a section on that in the Mask Primer. Go thru the masks on
Supplier #1's site, they list popularity, the more popular masks are one that are working for more people (reorders).
