What do these values mean?

Post by francois » Sat Jul 18, 2009 12:36 pm

I check my Smart card reader and I found the following values:

from 06/14/08 to 07/12/09:

Obstructive Apnea Index: 1.1
Average Hypopnea: 1.3
Average AHI: 2.3
Average Vibratory Snore Index: 1.0
Average Leak: 48.9

And for this week:

OA: 0.5-0.6-0.7.0.2-0.3-1.2-0.6
H: 0.9-1.4-2.4-1.1-1.5-1.1-0.6
AHI: 1.4-2.0-3.1-1.2-1.8-2.3-1.2
VS: 0.6-0.3-0.5-0.3-0.3-0.4-0.0

I am with 10cm pressure.

Are the results good or bad? I don't have insurance and I bought the machine myself.

Your leak appears to be too high. Your mask came with a chart that shows the normal vent rate. The rate varies according to your pressure. See what the vent rate should be for your pressure. The other numbers are good but they can be deceptive if your leaks are too high.

I checked the chart for the Comfort Curve. At 10cm H2O, the leak is 25%.

what do the graphs of the leak rates look like? are they flat or do they have lots of hills and valleys? can you post them?

so you are probably mouth breathing - your leak rate should be 25 - you said it was almost 50 average - OOPS

Yeah, you are going to have to get your leaks under control or you won't get effective treatment.
