Newbie DreamStation Auto BiPAP with humidifier and heated tube DSX700T11

[que0x]

Hi again,

************ Please note the I also disabled the comfort settings (C-FLEX) on the Dreamstation as well. It delivered much better results after then. *******

This is an update after one month use of AirSense 10 (Autoset/Elite):

1. I still got apneas. either hypopnea or central. I can't really tell, but it sucks!
2. I activated the climate control, and had heated tubing. Didn't help either.
3. I disabled the EPR. I have had experienced less apneas since then.

After switching between AirSense and DreamStation I decided to stick to DreamStation for the following reasons:
1. Less apneas, actually almost none.
2. Quieter.
3. If feel less tired during the day. Not sure because of the aggressiveness of AirSense. AirSense waked me up every time it detected an apnea. It "over-reacts" in my opinion.


Both machines are set to use Auto-CPAP (pressure from 4-20).

The AutoSet and the Elite are two different machines.  The Elite is a straight pressure Cpap.  Which were you using? Also, your thread title suggests you are using a Bipap, but your posts suggest Auto Cpap. Which is Correct?

3. I disabled the EPR. I have had experienced less apneas since then.

Disabling the EPR usually brings the Clear Airway events down.

Unless I’ve missed something, you haven’t said what your AHi is.  It is good that you are feeling less tired during the day, and yes the ResMed machines have a more aggressive algorithm than PR machines.

Both machines are set to use Auto-CPAP (pressure from 4-20).

This is a wide open pressure range and for most folk is not optimal.  My suggestion is based on Auto Cpap not Bipap. Please clarify what you are using.
If you look at what your 90% reading is, you can set a range surrounding that number, usually a good start is to set the minimum pressure  2cm below  and the maximum pressure 2cm above the 90% number.

I suggest that you download the #SleepyHead software so you can tract your data and progress. This way you will be able to see exactly what Apnea events you are having.

We need to add to this.  With EPR on, and the pressure range set from 4-20, obstructive apnea and hypopnea will be increased, and the incidence of central apnea may also be increased to the the variable pressure.  Using EPR with a pressure range that begins at 3, means that when the machine detects the need to increase pressure, it cannot increase EPAP until the EPR effect is overcome, i.e. with EPR at 3, the pressure will increase 4/4, 5/4, 6/3, 7/4, and only once pressure rises above the minimum CPAP pressure.  It is EPAP that must rise to prevent OA.  Such settings greatly undermine your therapy.  It makes sense that reducing EPR reduced events for this user, however, EPR may not be a cause of events due to poorly structures pressure settings along with EPR.

Just to clarify:  Post #11 suggests he is using the DreamStation, so we are talking Flex not EPR.
Although the same principal, but does not work in quite the same way.

And, I’m on the same page as you.  EPR/FLEX may or may not be the cause of CA events, and yes, his settings  of 4-20 are less than optimal, which is why I suggested downloading #SleepyHead software.

We are only quessing without seeing data.

Thanks Opalrose! I missed that he switched machines.
