CSR Cheyne Stokes Respiration reading??
CSR Cheyne Stokes Respiration reading??
Have had my setup for a week.  Two separate nights had a high AHI with CSR recorded.  Is this actually CSR or just rounds of Apnea?    

Attachment shows 30 minutes from last night where all the green was recorded as CSR.  

Have pressure set from 4-15 - EPR on - auto climate w temp and humidity.   Full face mask.  Swallowed a lot of air last night too woke up feeling it go down.  

Still working to get a feel for things.  Trying to understand if it’s legit CSR or not.

Hi there.  It looks like CSR to me, but let's wait for some of the heavyweights to umm....weigh-in on this.

If your machine is really bottoming out fairly often at that low setting of 4, you are likely to have to do a lot of gulping.  Almost nobody can stand even a single hour of that low setting, and we strongly advise people to raise the minimum to at least 5, or even 6 to see how it feels for a few nights.

That is definitely periodic breathing but not likely CSR.  CSR has smoother curves on the start and finish.  

You are likely tucking your chin and causing positional apnea though.  This is prevented by stopping the chin from tucking with the use of flatter pillows, CPAP pillows, sleep Collars, anti-snoring collars, or loose fitting cervical collars.

I would like to see the full nights data before suggesting further changes.  Do work on that chin tucking though.

IDk much about it (bonjour is much more knowledgeable) but I'm less sure about the events at the right side of your screenshot, the ones that end with a ca event. chances are they are not CSR but keep an eye out for more, especially if you continue to see a similar pattern after folks help you optimize your machine settings. if it continues I'd at least mention it to my doctor for peace of mind.

CSR is a form of Central Apnea, so I think the ones marked as Obstructive Apnea are not CSR.

A figure in this Wikipedia article shows the gradual starting and gradual stopping of breathing between each central apnea in CSR:
