I thought that a CPAP would eliminate my apneas.  I finally got a copy of the test and it has me confused.  Could someone please look at this and translate it into easier to understand english?

Results from the Titration test (note: I was on the machine the entire time):

Arousal index: 13.3/hr

Final diagnosis: Effective

Maximum Leak: 0.56 litres/sec

My Doc's RX:
CPAP machine with nasal Humidifier with 15 minutes Ramp phase and drive pressure of 12.0cm H2O and a large face mask.


Anyway, thats the results.  There are some graphs, but essentially this is the data.  There is also one more table that I will post below if it can help anyone to translate this stuff for me.

Hi MikeV:
The CPAP titration was done with an AutoCPAP?  I'm not real crazy about that.

Your sleep efficiency and light sleep percentages are still a little askew.

Got the sleep architecture and related graphs?  That might provide some helpful information, like how well you did in different body positions, sleep stages, etc.

Thanks for the response.  I have some graphs, but will have to wait until I return to the US next week.  I'm thinking about just getting these tests redone when I'm back.  These original tests were done in Japan, which does have first rate medical care, but it seems like specialized care (like sleep testing) is not common and probably lags behind the US.  Not saying I don't trust the docs out here, but I think a second opinion isn't a bad thing to go for.
