When is it a matter of concern?

Talk about possible mask leaks. Do you ever wake up with your mask ajar and leaking?

median leak o.o
95% 0.0
maximum 33.0

apnea index 0.6
obstructive 0.5
hypopnea 1.0
AHI 1.6

...
apnea index 0.6 + obstructive 0.5 + hypopnea 1.0 + unknown apneas = AHI 1.6.

Hi Sleepster,

I think the equations would be as follows:

(total) Apnea Index 0.6 + Hypopnea Index 1.0 = AHI 1.6

(total) Apnea Index 0.6 = Obstructive Apnea Index 0.5 + Central Apnea Index + Unknown-type Apnea Index

Solving for the sum of Central Apnea Index + Unknown-type Apnea Index:

Central Apnea Index + Unknown-type Apnea Index = total Apnea Index 0.6 - Obstructive Apnea Index 0.5 = 0.1

So, if we presume the Unknown-type Apnea Index is zero (me50 didn't say what it was) then the Central Apnea Index would be 0.1

Unknown-type Apnea events are defined as apneas occurring when our leak rate is too high (typically well above 24 L/min, I think, like perhaps above 30 L/min) for the machine to tell whether they are obstructive or central. I think these unknown-type apnea events are not included in the Obstructive Apnea Index nor in the Central Apnea Index but are included in the total Apnea Index.

Take care,

Hi Vaughn

I couldn't tell you because the statistics portion of the report didn't tell me. It seems that when I look at the statistics by week, it all remains constant as far as the AHI's go. So, maybe there is a problem with my mask after all. I think I will put in a new seal today and see if it is better tonight. Thanks so much.

not that I am aware of. If my mask were slightly ajar, I probably wouldn't notice it; if it were really ajar, I would. I changed my tubing and cushion yesterday and I think I had a better night for leaks at least.
