Changes with a retest??

It can be a good idea to get a retest. I am finding that I have different Apnea that originally reported.

At this point I cannot figure out what happened.

My first sleep Doctor reported that I had Complex Sleep Apneas, with lots of centrals. He told me I needed a Bi-cap/ASV machine.

So I got a Phillip’s ASV machine.

I seemed to be doing OK but things were a little odd.

SO after three years of the Phillip’s system reporting hypopnea all over the place along with clear air and almost no obstruction apneas..

My retest has shown me to have NO centrals and to have obstruction apneas and lots of hypopneas.

It also reported that I can use straight CPAP, of a less complex APAP system. That I do better with a straight pressure and the only need is that if I stay on my side I sleep great on 10 CC/H2O, and if I get on my back I need 15 CC/H2O so a APAP will serve fine.

I have been told that my ASV machine might be overacting to my sleep and causing some problems on its own.

It reports NO obstruction apneas, it reports only clear air apneas and Hypopneas, I have been using bi level settings that was allowing these apneas…

OR is Sleepyhead miss reporting the info from the machine??

I now seem to be very different than originally reported.

Using this new report as I wait for my new machine to be ordered which should be http://www.thecpapshop.com/airsense-10- ... humidifier with a heated hose and new full/full face mask.

Meanwhile I have reset my old ASV system to 9.5 low and 10 as my high so that is nearly a straight CPAP machine, (read that the new machine does lower a little to help exhale.) It can also respond to my getting on my back with higher pressures.

Now for the past couple of days I am getting straight Zeros, NO apneas at all.

So the questions are:

Did my first Doctor mess up?? (Was he a quack??)

Or as he was offering to help me buy a machine pad the bill by ordering a most costly machine?? (I did not buy from him and used Second Wind CPAP)

Or did I become used to CPAP and no longer react as I had with my first sleep study??

you have to remember that one of the problems with sleep studies is that they are brief snapshots in the continuum of life, and thus cannot reasonably be expected to be comprehensive and absolute. and, also, that you have changed in the last three years.

whether the new autopap will work as well for you, or better, is something you need to keep using sleepyhead to monitor. just import the data into the same profile, that way sleepyhead can show you old and new data easily for comparison.

as to your concern about sleepyhead, it just reports what data the machine records, sleepyhead doesn't make anything up, (except the excess (lower) leak line in the leak chart... that it does it's best to calculate... the top leak line is reported from the machine, as are flow, and pressures and events.
