Clusters of mixed events - what is causing them?

[vsheline]

Correct me if I'm wrong, but getting the CAs down is probably the most important item to get corrected?

Often obstructive apneas are the most important to minimize. Which type of apneas are lasting longer, resulting in worse oxygen desaturations?

As soon as we feel the urge to breathe a Central Apnea ends.  I think Obstructive Apneas tend to last longer and require arousals to start breathing again, which interfere worse with sleep.

My own suggestion would be to raise the Min Pressure without raising the Max Pressure.

Take care,

Thanks for the input.  Yes, both are certainly not good, but with the CA you may not get an "urge to breathe" cause it is already missing the response from the brain to take a breath.  My total time in apnea for OA or CA was about the same and when the min. pressure was raised the CA component doubled and added a number of CSR events as well.  Most input so far from other posts and what I read indicates that the CA events are harder to reduce than the OA events and the CA requires different equipment to control if it cannot be minimized with APAP or CPAP.  Sure looks like there is not an easy solution to mixed apneas with any CA components.
