Doe find the ds2 very inefficient?

[sleepistryingtokillme]

I had the dreamstation 1 my ahi was consistently below 1 my average pressure was 14-15 cm/h2o and was going down as I lost weight about 50lbs at this point. Enter the ds2 I got as a result of the recall and my ahi is routinely between 2 and 4cm/h2o and my minimum pressure is now up to 17cm/h2o. The machine doesn't even feel like its putting out enough pressure, it just seems very inefficient and I'm wondering if I'm the only one noticing this.

Post OSCAR charts from a typical night on your DS1 and DS2.

Configuration changes could explain the differences (pressure range, flex). We could also see the type of Apneas Obstructive vs Clear Airway.

I noticed a difference between Dreamstation 1 & 2. I had to increase the pressure of DS 2 by 1 to get the same therapy effect as from DS 1.
