Bad last hour and half

Post by Guest » Thu Mar 23, 2006 6:10 am

Hi Everyone,

Have a question about what happen last night. I have been have great success ave. AHI is 1.2 for the last three weeks spread out through the night I have never had a NR apnea. Well last night between 4:30am and 6:00am I had 38 apneas and two NR's. The average duration of the Apneas was 11.4 seconds. I awoke constantly and then right back to sleep I knew I was at the high end of my pressure setting (15.0cm) because my Swift mask kept loosing its seal. So I would toss from side to side trying to get the mask to reseal, it would for short peroids, or at least that what it seemed to me.What defines what a NRA is? From the graph they looked very short less that 10 seconds. Is it just repeated apneas over and over until its declared non responsive so then you get a blip on the NR graph?

The next time this happens, try turning off and then back on your machine to reset it to you low setting.

Also, what is your normal 90% pressure compared to your high setting? Your high setting probably shouldn't be much higher than you 90% pressure.

Jim,
My 90% pressure for IPAP is 13cm and EPAP is 10cm. I cannot figure what caused so many apneas in such a short peroid of time. When I awoke and check my machine pressure at that time it was 12.5 IPAP and 9.5 EPAP it is on a Flex setting of 2 so it varies around these through the respiration cycle.

The suggestion to turn off you machine is a good one. It sometimes happens, for reasons I'm not sure I can explain, that the machine just goes berserk - it misidentifies something in your breathing pattern, and then bangs its head agains the wall trying to fix it. Maybe, in your case, it started with a leak the machine couldn't handle.

As far a Respironics is concerned, a NonResponsive apnea is one that it tried to nudge away by slightly raising the pressure (3 times), and the ostinate thing simply wouldn't ...respond. An NR is "couldn't handle this one". But what you describe sound like a whole buch of hardly handled events.

If you turn the machine off, reseal your mask, and turn the machine on again, chances are that the viciuous cycle will stop. You write I knew I was at the high end of my pressure setting (15.0cm) because my Swift mask kept loosing its seal but it could really be the other way aound: You were at the upper end of the your pressure because the mask lost its seal to start with.

Hope it doesn't happen again soon -

O.
