What do you guys think?

I'm trying my hand at posting charts for the first time, and so I hope this works.

I'm going to post a chart that shows a typical hypopnea that I experience.  Can anyone look at this and tell me what's going on here, particularly in the two breaths **before** the hypopnea actually occurs?

   

Also, sometimes I get a group of apneas.  When I zoom out, it kinds looks like CSR to me.  What do you guys think?

It's called a sigh. It's a normal for it to happen during the night. Just a person talking a deep breath and letting it out. It leads to suppressed breaths for few seconds. It's not a hypopnea but the machine counts them like one.

Walla Walla,

Thank you very much for responding.  

I find that the many of my detected events look just like this one.  Are you saying that, when computing my AHI, I should disregard them?  In other words, they are not apneas, and a higher pressure will do nothing to resolve them?

Interestingly, if I'm using a machine with Central Apnea Detection turned on, it often fails to see the tiny breaths, and counts it as an **apnea**.  If I'm in autoset mode, the pressure will increase as well.

Do you have any thoughts on the second graph that I posted?

Here's another image showing what looks to my uninformed eye like periodic breathing.  Again, I'd love any thoughts from people with more experience than I...

It looks like it's obstructive flow limitation. The first chart had unknown events but I think they were obstructive. Same with the second chart but they're not counted as events because they don't last long enough. Well that's my guess until Sleeprider says I'm wrong. Too-funny
