Too much STATIC showing in OSCAR Flow Rate

[PappaJoe]

Okay.
Resmed 11 on Auto  pressure: 12/15 EPR 3
Not pretty, is it?
Leaking looks bad.
Mouth was taped shut.  
I removed the V-com from the circuit.
That has shown to be effective against leaking.
I hope you haven't given up on me yet.
Anxiously awaiting your replay.

Waiting on others input, but one thing I'm seeing that's not helping is the frequent leaks.

[PappaJoe]

Battled excessive leaks last 2 nights.
Finally got a halfway decent stretched this morning.

Pressure is 15/12 with EPR 3
does that make an effective Epap of 9?

Thanks in advance for any suggestions.

P.S. I've noticed the I:E ratio is quite tight.
Could that be causing a CO2 buildup that triggers an exaggerated breath cycle every few minutes?

[PappaJoe]

Last night's data
I swear that mouth leak near the end just don't seem possible.
I'm taped up tighter than, well, I don't know what.

My goal is something like what's showing between 1 and 1:30, and between 2:15 and 3:15, isn't it?

Anyway, should I move pressure max  up or min down?
Or, switch to a bilevel and start spreading them? (I have a Airsense 10 Autoset)

Couple of points. 

I think it would be easier for analysis if you presented your graphs always including the events graphs, something like this :-

1. Events
   
2. Flow rate
   
3. Pressure
   
4. Leak rate
   
5. Flow limitations
   

Having the events graph always included is pretty important in seeing what is going on. This will give us the breakdown of events between central, obstructive and hypopneas. Your last graph had the events graphs excluded. 

However, your first graph of 21st April did indicate only 3 hypopneas, using a pressure of 12.6. No obstructives, no centrals, no positional apneas, on the face of it a good result. 

I just wonder if this pressure is overkill? It could be an issue with your comment on leaking? 

Previous members did mention also dropping maximum pressure. 

A note on taping and leaks, make sure the corners of your mouth are well covered by the tape. Also useful to use  baby wipes to clean skin before fixing.

What was the initial pressure prescribed after a sleep test?

Your flow limits have risen.  Are you using EPR full-time set at 3?  If not, you need to be.  I can't tell if you are using ramp, but if you are please turn it off.  You get virtually no therapy during ramp.

[PappaJoe]

Got it.  Screenshot with graphs in proper order.
Will adhere to the program.
Original script was cpap pressure 13, EPR 2.
I have been running EPR 3 since this thread.
I tape with 2" cover-roll stretch tape, an inch to either side of mouth.
I am nearly deaf. could there be a hose or machine leak that looks like mouth leak?
No ramp used.
Thanks for taking the time to help.

You already have the EPR set to 3 full time.  leave it alone, you could raise the min pressure by .6 and see if that helps. Otherwise  leave the setting alone, let's see another night oscar.

[PappaJoe]

Sorry, missed this post before going to bed.
Pressure remained 12/15 EPR 3 FF mask until 5a.m.
Switched to P10, taped mouth tight, cervical collar and dropped pressure 0.2.
Tonight I use 12.6/15
Thanks again for sticking it out.

[PappaJoe]

Increased min pressure to 12.6 as suggested.
Used F20 mask hoping to control leaks. (it did)

Tried cervical collar first half.  (Just read bit on SCC and learned much there)
The SCC velcro hurts my neck.  Need to find a large 'dickie' and try again.

Wondering: EPR treats FL. Yet machine INCREASES expiratory pressure upon increased FL?

The flow rate shown here is exactly the non-static sleep I'm trying to achieve:

Thanks for taking the time to help.
