Hi Group. Glad I'm here. Have been on my VPAP machine for 5 years with no followup after sleep study in Oct. 2008. From my profile you can see equipment used. Have been using religiously since starting therapy but never bothered with actual therapy results as my symptoms subsided and I feel much better after having startied therapy and sleep much better when on machine.
Just recently downloaded ResScan 4.3 from this forum. Thank you. After getting necessary null modem cable the other day, I started downloading my results because I really wanted to know my AHI and AI results especially since I lowered the IPAP pressure from 18.0 to 17.0 more than two years ago to try to get more comfort from my mask.
I'm dismayed because for last 2 days of downloads no AHI or AI data. Those readings are 0.0 Is this possible that my therapy is so good that I'm not experiencing any apnea/hypopnea events?. or could there be a malfunction with my machine? I'm getting back other results for respiratory rate, minute ventilation, leak, and tidal volume but again 0.0 for apnea index, hypopnea index AHI and % time in apnea.
Hope you can help me come up with an answer. Thx. Seth[/size][/font]
Seth, other more experienced members will give you better info I am sure. What were your AHI numbers previously? There are some members who have experienced 0.0 but I think that is rare. If your numbers were really low, like less than 1.0 it might be that you are doing well. I think you are right in being suspicious.
If you don't get a definitive answer, you could try as an experiment tonight, by holding your breath for 10 or more seconds. Note the exact time that you did this and it should show up in your data. It's a cheap trick but it might answer your question.
Yeah, two days of 0 AHI is hard to hit. My first suggestion is to unplug the machine from the wall, wait a few minutes, then plug it back in. Check it again tomorrow.
If you are going to trick the machine like drgrimes suggested, you need to pause your breathing after you breathe out. Else the machine may not read it right. You need to hold your breath for at least 10 seconds, preferably longer, to make sure the machine records it. Less than 10, it won't note it. Right at 10, it may not either.
Do you get flow rate? If you do, then you can zoom in and look for flat lines in those two nights. That's an event.
