What are these strange events on the waveform that I circled in black? I think they are arousal, but there is nothing to cause them. No pressure changes at the time they happen, no apnea or hypopnea when most of them happen. They also look like hyperventilation events.

We are not professionals here. Therefore no one here should be interpeting raw data of which there are probably several explanations for the results. This data isn't even labeled with the leads it refers to. We do help people understand their final sleep study report after it has been interpeted by, what we hope, is a competent physician however.

Sorry what do you mean by lead?

He's showing the flow data recorded by his CPAP. It's respiratory. You can see the "lpm" on the scale on the left.

Oh, got it, it looked like 1PM to me.

Here is the one prior if it helps.



The orange box I am awake and the red box is when I am a sleep.

i have absolutly no clue how to read these charts but i know that i have many arousals that are spontaneous and do not corilate with any respritory event... so if they are arousals, which im not saying they are or arent, they could just be spontaneos arousals. it could be from insomnia which mine are probably from but im not sure... ive never spoken to my sleep dr about these arousals and he never mentioned them to me...
