Strange readings with ResScan software

I have a ResMed autoset 10 CPAP machine and have been monitoring my readings using the ResScan software (as well as Sleephead) for quite a while now. During the past week, I've been waking up around 4:00 or 5:00 AM for a bathroom break and take my mask off. When I return, I put the mask back on until I wake up for good. Before my bathroom breaks, the readings show very few CA events. During the time period between my bathroom breaks and until I wake up for good, my CA events have been doubling. It happens regardless of which side I sleep on. I don't fall back asleep all the time and when I don't, I am aware of my breathing patterns, which are normal.

Any thoughts why my CA's would double during this time frame?

Thanks

When you say doubled, from what to what?

I've had several instances where the CA's have been 3-5 events for most of the night and then jumps up to 6-10 (on a few instances more than 10). For example, I would have 5 CA's from 11:00 PM to 5:00 AM, go to the bathroom, put the mask back on and have 10 more CA's from 5:00 AM to 7:00 AM for a total of 15 CA's for the whole night.

As you fall asleep, it is quite common for your breathing to become a little irregular for a short period as you pass from wake to sleep. This will result in a number of events that could be either central or obstructive. These events are called onset events because they happen at sleep onset but disappear quickly once sheep is properly established.

The number of events you describe is very low and could easily be explained by onset events as you get back to sleep. Also, toward the end of the night your sleep drive is reduced and your sleep is more likely to be disturbed. When your sleep is disturbed you can have another small cluster of onset events as you settle back to sleep. This could account for why you have more at the end of the night - simply because you are a little more retless after your toilet break.

This is all guess work of course. Whatever the cause, the number of events is so small it is almost certainly no cause for concern.

Thank you for your input Sleeptech. Makes me feel a little more reassured.

Much appreciated !
