Air Blowing in my eyes

Post by vapat75 » Mon May 31, 2010 12:06 pm

Last night was the third night using my cpap machine resmed S8 Elite II, resmed mirage quattro full face. My hours use was 7.39 hrs, leakage 0.28 L/S, AHI 4.0, AI 0.0
HI 4.0, I had difficulty last night with the air blowing into my eyes, i did some adjusting with the forehead dial and finally got it to stop, also I had condensation in my mask and in the hose as well, my humidifier was empty. My window ac unit was on colder setting and the air was blowing toward my hose and me. Would the humidifier being empty when I woke up case the condensation in my mask and hose. My setting are ramp, 4, 8 pressure. I noticed when I got to the 8 pressure the mask would start to leak. Also it get a itch on face or nose every night I have used it and had to loosen it to scratch. I think I will just not use the ramp and adjust my mask at the 8 setting. My exhale is set at med. Are these good numbers? and what do they mean, AHI, AI and HI.

I use the Quattro with a pressure of 11 and I have few leak problems. When I do feel a leak at the eyes, I can sometimes simply tuck in that area without taking off the mask. Also...when putting on the mask, try to place it against your chin and then bring it up to your nose area. Another thing to try is lowering the mask about 1/4 inch so it fits lower on your nose. One other thing to consider....I found that the Quattro runs a little larger than some other masks. I was told that I needed a Large, but I had to exchange it for a Medium. Be sure you have the right size.

PS...Your numbers are excellent

Turn your humidifier to a lower setting = no condensation and no empty tank. You don't need it, it's just a convenience, comfort, but if it's too high, and especially if the room is cold, you will get rainout (condensation).

AI is apnea index, HI is hypopnea index, and AHI is apnea hypopnea index, which is the sum of the other two. All of them convert raw numbers of events to events per hour. Zero apneas per hour is just what the doctor ordered. Apneas are cessations of breathing for ten seconds or more. Hypopneas are, roughly speaking, incidents when airflow is restricted but not stopped. The definition is not uniform for all researchers or devices, and the S8 Resmed family of flow generators (great little machines, love mine) have a reputation for being generous in their measurement of hypopneas, so people using an S8 tend to record a higher HI than they would using something else. Four is a fine number on an S8, but when you get all the other kinks worked out and feel comfortable with the machine, you may find that improves on its own or you can improve it.
