Posted by James Vines on December 13, 1999 at 12:12:09:I had an unsuccessful sleep Titration of nasal CPAP.
I was told that it was a CPAP test, however it was both Bi-Level and CPAP. I did not find out until later and not from the clinic. I was given minimal information. During the test I awaken several times with the machine pressurizing prior to the end of a long drawn out exhale(this occurred the entire night). The clinic had no explanation for this and wanted to retest me at my expense. The doctor implied that it was a psychological problem. The tech described it as my fighting the machine. They tried all kinds of pressures, tying my jaw shut and a full facial mask plus O2.
On the diagnostic test without CPAP, I had 8 central apneas. With the test it was 139 central apneas. My question is if the Bi-Level Machine was set incorrectly, that is to pressurize early in the expiration cycle, could cause the recording equipment to record the event as a central apnea?
I have read that CPAP aggravate central apnea, but it seems that a 8 – 139 or 1700% increase seems a bit much. Also during the diagnostic test, my blood O2 bottomed out at 91% and averaged 95% with no desaturations. The titration test had an average of 96% with 46 incidents below 90% and a minimum of 68%..
CPAP is not supposed to help central apnea based on my limited knowledge so in order to make a decision to have an expensive test, I need to know if the central apneas are real or caused by a incorrectly set bi-level machine.
To complicate the situation, the clinic, put me on a CPAP machine for a brief test and I not only tolerated it, but dozed off and felt very good.
Thanks
Jim
