No Flow while awake

RE: No Flow while awake
the 142 plm occurred during asv use. if for the sake of discussion each of 3 modalities were used in equal time that'd be 46 minutes each. that's 108 periodic limb movements during 46 minutes of asv use. no matter how you look at it, that's not conducive to good sleep.

RE: No Flow while awake
Here is a tip... when the pressure on your ASV just spikes up it can make it impossible to get to sleep, just blow air back at it.
When I first started ASV, that was happening to me, I found that advice and it knocks the pressure spike down and helps getting to sleep. John

RE: No Flow while awake
A decent amount of sleep last night, but not enough. Only 2 Hs. no OAs, no UAs.
Made 4 changes. 1. Min PS to 3 2. Changed Mask to Philips Wisp 3. Used a chin strap 4. Did not go to bed until almost midnight. Charts attached. there is a peak win I disconnect at 1:45 to use the bathroom. And a break at 5:20 to try and readjust after waking to try to go back to sleep. I dd not sleep after 5:30. Something made a huge difference! Maybe because I actually fell asleep!!! No UAs. Wow, from a hundred to nada. Whatever, THANK YOU, for your help! I hope I can repeat this. A question: What exactly is flow rate? And why would it be zero in the earlier charts? Another: Does head and neck position affect anything? TIA

RE: No Flow while awake
Flow rate:
Flow Rate is a measure of how fast air is entering or leaving your lungs. Values above zero mean you are breathing IN Negative values mean you are breathing OUT The bigger the absolute value.. the faster the air is entering (or exiting) your lungs. Head and Neck position: Not sure what you are asking here but if you tuck your chin down onto your chest that may cause a "strangulation" effect in your throat and cause restrictions and obstructions. When people get into this "chin-tuck" position we often see tightly packed groups of obstructive apneas in quick succession until they straighten their neck again and open up the airways. That's why cervical collars are often recommended in response to seeing clusters of OAs packed together in quick succession. Does that help? EDIT: I didn't answer the question about zero flow rate. If the flow rate is truly zero then you have probably taken the mask off and time is passing without any data being recorded. If the flow rate is small amplitude (but not totally zero) then your breathing is very shallow and may be waxing and waning.

No way I was holding my breath while I was awake during that period. It must be some anomaly. I've ordered a cervical collar to see if it works better or is more comfortable than the chin strap.

RE: No Flow while awake
Now I understand the zero flow rates you are referring to.... we are looking at your first post....
The first plot is a zoomed plot..... the breathing there is waxing and waning (deeper then shallower then deeper again). It's not truly becoming zero and "flat-line". The second plot is a full night plot.... the period from midnight to 5:30 is the other category... you took your mask off so no data was being recorded. Make sense?

"The first plot is a zoomed plot..... the breathing there is waxing and waning (deeper then shallower then deeper again). It's not truly becoming zero and "flat-line"."
Even when I am awake? And I know I'm not shallow breathing. Change in pressure and this went away. "The second plot is a full night plot.... the period from midnight to 5:30 is the other category... you took your mask off so no data was being recorded." Yes. Mask off but machine running. Sometimes I turn it off then back on after restroom stop. |
