First Night Results on CPAP
#1
I think I had a good start.  Tried to take screen shots but was having issues that need to be resolved for future posting to obtain meaningful feedback.

ResMed AS10 Autoset 6cm-10cm

Brief summary of last night is:

5.09 hours 

AHI 23.07
Obstructive Index 3.21
Hypopnea Index
Clear Airway Index 19.86
RERA Index 0.0

Ave Pressure 7.38
Min Pressure 5.0
Max 10.0
90% pressure 0.0
Ave EPAP 5.29
Min EPAP 4.02
Max EPAP 7.00

I pretty much understand this except for the Clear Airway Index 19.86 - what is this?

My thought is to change the max to 12 cm h20

I know this is limited without screen shots but does anything stand out - other than the CA at least in my mind.

Thank you

It's not unusual for CA to be present as you start CPAP therapy, but the wrong response is to raise pressure. CA is an apnea that occurs when the airway is not obstructed. There can be any number of causes, from simply changing your position in bed, or holding your breath, to actual respiratory suppression caused by an imbalance in CO2 (see "respiratory drive and central apnea").

Generally we recommend minimizing pressure fluctuations, lowering pressure and reducing EPR when CA is present. In your case we can give it another day or so before making changes, but you are using EPR at 2; try turning that to 1 or off before making other changes.

Man this is exactly what's happening to me in the first week, and what I've just started getting help with here. Just for your reference, since it was confusing for me at first, Clear Airway = Central Apnea. I think for me, my body is confused about this machine, and is stopping breathing, in my case, for around 10 seconds at a time.

Ten seconds is very short, the minimum in fact, for it to score as an apnea.

If the CA's have a much larger duration it's more of a concern. It's important to wait a few days to give the body time to adapt. Don't make any changes to the pressure until then.

What were your numbers like in your sleep study, before they hooked you up to a CPAP machine?

What were your numbers like in your sleep study, before they hooked you up to a CPAP machine?

Total 403 minutes
116 apnea’s index 17.6/hour
104 hyponea w/ index 15.7/hour
220 Apnea & hyponea with 91 OBstructive, 18 Central, 7 mixed, and 104 hyponea for AHI33.3/hour
Lowest SaO2 was 83% ave 94% duration less than 88% was 2.4 min
Snoring severe
105 arousals (15.9/hour).  20 respiratory, 0 leg, 85 spontaneous
O PLMS

Is there a glossary or definition of all Sleep Apnea terms somewhere on the board?

Thank you.  

I think leaving pressure range as is 6-10 is fine and see what a week looks like.

Then you've already got a huge improvement!

Definitely. Your CA index will likely drop in that time. If not, we'll have enough data by then to make recommendations about pressure changes.

Changed EPR from 3 to 1 to try tonight

Thank you

THIS is what I've been looking for.  Did a search on forum/board but missed it.  Now on my desktop and printed in my sleep apnea journal started today.  Thank you!!!

Will do with EPR changed from 3 to 1
