Is there something on my sleepyhead report that is concerning? I had another night of zero events last night. My way of thinking (and I could be wrong) is that once you reach the golden numbers of 00 you should not mess with anything. The numbers I am using are: Epap=6 PS min =4 PS Max=12.6. If there is something else that I need to do or look at please let me know.
For all I know the machine is malfunctioning because 00 two nights in a row is suspect to me, but I have never had experience with AVS, so many questions........
Vaughn....By the way I also have chronic bradycardia. Thanks for helping me, and if you could clairify what it is you want me to know I would appreciated it.
The point I had in mind to make, which I now see I neglected to actually state (silly me), was that it looked like the Pressure Support can stay where it is, that there appeared to be no hurry (indeed, there appeared to be no reason) to walk the Pressure Support up to 15, because no times were visible when it was higher than about 8. (EPAP + PS = IPAP, 6 + 8 = 14). And if the statistics were valid and IPAP really was shooting up occasionally close to 19 (even though we do not see it doing that on the IPAP time plot), perhaps this was only during occasional swallowing.
But actually, on second thought, I think we would need to be looking at the "High Rate Pressure" plot to see more complete detail.
There is no reason to suspect the 36007 machine is not working correctly. Unless my Leak numbers get very high (above 40 L/m) my nightly AHI is pretty much always zero. If the machine is adjusted well and Leak stays low, I think zero AHI nights are not uncommon for the average ASV user.
By the way, I use a wrist-mounted Pulse Oximeter nightly, and my chronic bradycardia improved when I raised my minimum Pressure Support to 5 or 6. I was using 6 as my PSmin for a long time, but I've backed it off lately to 5, because my Oxygen Saturation had often spent long periods maxed out at 98 or 99, which might be unhealthful. Too much O2 in the blood can create problems -- more oxidation, more free radicals, things like that. At many hospitals they are careful not to give too much O2 to patients nowadays, because of the problems too much O2 was causing years ago.
