Thank you for the response. Food for thought.
Thank you both...
My wife has a Dreamwear mask with a Resmed Airsense 10 APAP. Yesterday, her mask leakage was 20 L/min, and her AHI was 1.7. This morning, her leakage was 35, and her AHI was 1.8. On the 25th, her leakage was 26 L/min, while her AHI was <1.0.
It seems that there is little relationship between the two. Ideas???
Since starting using my CPAP, I have lost almost 30 pounds. By the end of the year, it should be closer to 50 pounds. My study showed an AHI of 27. Since the first day of using my CPAP (setting = 10), I had a low mask leakage...never more than 4L/min, and usually 1 or even zero. My AHI has never been above 2.0. If I ask for another student at the end of the year, one year after starting, I have a couple of questions:
Should I discontinue using my CPAP before the study?
If so, how much before?
Medicare picks up 80% of the cost. Still about $100+ out of pocket. If it is used for at least 4 hours a day for 21 days out of 30. The "rental" is picked up by Medicare after 13 months, and the machine is yours. Supplies are very inexpensive. The only sites I found for reviews are:
The ink is to Amazon, which has great prices without insurance.
I have used a CPAP for less than a year. Its' funny, but the sensations are similar to my scuba regulator...except through the nose. I find that the APAP might actually inhibit my breathing. I found that a slow ramp time left me trying to inhale more than the starting pressure. So, I have a ramp time of about 10 seconds. Now, I have a setting of 10, which I gather is about the lowest standard setting. My mask is comfortable, and I use it even when I take a nap.
With a prescription, you might be able to find another source (CPAP.com; Amazon, etc.). If you have a PayPal account, you might be able to spread the payments out through mail order. Try to find a similar, but less expensive, machine. Give it a try.
My unit has 5 bars...and still it may be ours. My wife has the same machine on the other side of the bed. Hers is posted [sometimes] hours before mine. I did raise the issue with ResMed, and it seems to have improved.
My wife is using a Resmed system with a Dreamwear mask. Her AHI score is <5 consistently, but she frequently has a mask seal score that is excessive (>24 L/min). It seems like her mask seal is totally independent of her AHI score for the night. Even when she has an excellent mask seal, her AHI does not change much.
I have the same setup, and my mask seal stays below 5 L/min; and my AHI only goes about 1.0 about once a month; and, it, too seems to be independent of the mask seal.
I have had the Wisp, and now the Dreamwear. They both have an "overflow" air exit. The nasal "pillow" on the Dreamwear has two or three microholes on the front to ensure the air is equalized. If there is a real leak, you will hear the rush of air. As long as the air is not coming from around the fit to your nose or around the tubing, all is good.
