Hi, I keep hearing that the resmeds give a higher HI score. Anyone know ? My AI is like 0.5 and my HI is like 6.0 or 7.0. getting the AHI over the goal of <5.0. any feedback is appreciated. Mike

I have that machine too and my AHI is usually like 1.8 and the AI is 0.0. The HI is usually the same as the AHI.  That is what it shows me on the screen when I look at it every morning.

Not sure if that helps, I am new to this.

If I remember right, don't you have problems with depression?  I had a heck of a time getting my ahi under 5.  It took 18 months to wean myself off of effexor, and now it is running 1.5- 3, hovering around 2 most of the time.  I have no idea why, but I swear the effexor had something to do with my high ahi.  It would be interesting to have another sleep study to find out if I am still in the mega-severe range.  Virginia

This is probably a stupid question and I apologize, but I am not familiar with a lot of these home machines.

If you are using one of these data capable machines and you have a spontaneous arousal followed by a central apnea... will it factor that into your total AHI at the end of the night? It would HAVE to, right?

I believe it would.  I know the elite can't tell the difference between centrals and obstuctives. At least it doesn't  show it on the totals.  Could some of these anti- meds cause centrals?  Virginia

Well, I wasn't thinking of medications causing centrals, but the EFFEXOR that you mention has been shown to increase limb movements. So the AHI increase could be a result of a few more limb related arousals per hour... maybe? Im just guessing here.

I guess that's a possibility.  I used to toss and turn a lot,arms and legs, so much that we needed a body pillow between hubby and I so I wouldn't hit him in the face. Most of that has calmed down now. The reason I ask is that I have never had a study where I slept any more than an hour or so with my titrated pressure.  The last time I had retitration in the lab, they started me out at 2 and worked up to 20, and it took them almost all night to do it. Why they started at 2 when my previous titration was at 12 I have no idea.  I clocked in as high as 144 events at 14, then things got better and settled down around 18, if I remember correctly I was still having 4 or 5 events an hour at that and about the same at 20, so we settled in at 20 for a while. I think I had 17 total central events for the night.  I still had problems for a few months so we did an in home two week titration and reduced the pressure to 17, which seems to do the job for me, at least after I got off of the meds. I wonder if more centrals would have showed up if I had had more time to sleep.  I don't remember any mention of leg movements though, I'll have to look up the report, I have it around somewhere.
