been on new PR ASV machne a week ahi going up

I finally got my RESMED yesterday. Last night was the first night on the RESMED. My AHI was down to to 0.1 but the most important thins is that I feel better. I am more rested today. It may be in my head, we will see.


The RESMED is more aggressive. Here are two pictures, the first is the RESMED response the second is the PR60.



notice how quickly the pressure adjusts.

This is the similar time span from a PR





this is how long the PR takes to adjust the pressures.



The RESMED is certainly more aggressive. But it does not bother my sleep. IT may be that after 3 years on the RESMED I am use to it, but the RESMED seems to be the better machine for me.


I now need to see how far down I can take he pressures and have decent sleep.


I DO LIKE SEVERAL THINGS FROM THE PR that I wish the RESMED picked up.

1) I like the tracking of eap and iap as separate lines
2) I like reporting of trigger breaths

If nothing else they were interesting. But on the RESMED, when my ahi was 0 on very low settings, I thought that I might be able to get off of the machine. What I cold not tell was when the machine was triggering the breaths, which was very often,,,,, which is why I need the ASV.

I want to thank everyone one more time for all of the support. I know I drop in and out often, and appreciate that you always welcome me back with open arms.

Hi wilsonintexas,

Thanks for the follow up and I'm glad it's working for you with the new machine. No more aerophagia problem? As for the 2 pressure lines for Resmed it's probably because you have an AirCurve 10 and there is some bugs with Sleepyhead and some new Resmed machine, hopefully it will be fixed in the next version of SH. FYI, I have a Resmed S9 Adapt and I have 2 pressure lines in SH.

After 2 night with the aircurve, with it set pretty wide open I ham having problems with the aegro today. I have hit the malox gain and felt pretty miserable.

I just lowered the pressures a little to see if I can get it under control. I will also put on the o2 meter for the next few nights to be sure I do not cause problems. BUT on the RESMED I was down to the lowest settings on the older machine.

I did sleep better, I guess my body is use to the algorithm, and it probably likes not going into the hypos. But I hate the aegro. I know it is bad, when I I am brushing my teeth and it keeps coming up,,,,, and out.....

I will update this again in a week or so, when I see if I can get the aegro back under control.

Last night I limited EAP to 6 and mas Ps PS down to 8. My ahi was 0.1, with a eap of 6.8 and a iap of 9.8 (according the the readings on the machine. Seepy head does not show the two pressures yet. I had on the 02 meter on and I never got to 88, but I spent a lot of time at 90. I also had a few times when the pulse jumped quickly, this was aligned with a rise in pressure, uneven min vent, and a drop in 02. No apnea but I was responding to something.

I think I an going to raise the min ps a little to see if I can reduce the pressure swings. I will see if the aegro does. It is a little beter today, I will have to see.

If anyone wants to see the sleepy head data let me know. I am on sleepy head 0.9.8 I will see of there is a later version.

Thanks again for the time.

Been on the AIRCURVE a few nights, sleeping better, still a little aegro. have lowered the max eap to 6, and the PS to .6 - 9. My ahi is 0.1 which is just one event. I will track the pressure and see if I can lower the PS a little at a time and see how it goes.

so far it fits me better that the PR. But this is probably like masks, you have to find what works for you.

But I am reminded of the discussion with one DME who said that she had 5 of the PRs returned, and they all went with the RESMEDs.

Greetings! My neurologist / sleep specialist put it very succinctly. The algorithm for the PR System One ASV is designed to encourage the patient to breathe as much as possible. Not until it is clear that intervention is required does the PR System One ASV unit intervene. The thought is that helps encourage normal functioning. Some patients feel as if this approach means the unit does not follow their breathing as well. However, the Resmed algorithm for ASV therapy is much "tighter" to the breathing pattern of the patient. It does not allow the patient as much leeway. Some patients feel as if the Resmed unit forces them to breathe - whether they are ready or not. I liken the difference to driving a sports car (Resmed) versus driving a luxury car (Respironics). Different approaches. Different benefits. Both will get you there. I've used both. I can't say that one is better than the other. Just different. I do know form my own experience that the Respironics unit does a fine job of jumping in and helping me breathe when I fail to do so.

I appreciate the reply. I agree that they are very different approaches.

For me, the PR was very inconsistent. My AHI varied on it from 2 to 13. I just never slept as well on the PR as I did on the RESMED.
