Apnea is a 75-100 percent reduction in ventilation for more then 10 seconds and hypopnea is 50-75 percent reduction in ventilation for more then 10 seconds. That makes it sound like hypopneas are better than apneas, but having either can result in brain arrousals and/or oxygen desaturation.

The RDI of 48 per hour on CPAP at 15-16 doesn't sound right. Do you feel you slept better with the CPAP on? Are you sure these figures are not just the first study and you are mis-reading the report? If you are truly still having an RDI of 48 per hour with CPAP, then your doctor should be perscribing a Bi-PAP machine with higher pressures to eliminate those events. You should no longer be given a CPAP to use since those results are usually unacceptable. Bi-PAP machines are higher technology machines that can usually go higher and can be set for different inhale and exhale pressures.

Maybe that report was just for the time that you didn't have the CPAP on? Call your doctor back and ask for clarification.
