sleep apnea and arousals
My oldest son (now 3) had his tonsils out at 2 yrs 8 months because of sleep apnea and enlarged tonsils/adenoids.
Now my youngest son, who is 21 1/2 months, was just diagnosed with sleep apnea. He has 10.1 apneas during REM sleep. I am aware of this because of my oldest son.
What is new to me is something called arousals. I was told that in the 4 hours and 58 minutes that my son was monitored for, he had 170 arousals. What does this mean? It seems like ALOT to me. Thanks

Well, yes, divide 170 arousals by the number of hours he slept and it sounds like it could be a lot of arousals. An arousal doesn't necessarily mean that someone is fully wakened from sleep but it does mean that the person abruptly changed from one stage of sleep to a lighter stage of sleep. Beyond that explanation I really can't provide any clear explanation. Rock Hinkle gave me an excellent explanation of arousals but I don't have time now to dig it out and I don't feel confident enough to explain from memory.

An arousal is an interruption in sleep. These events must last 3 seconds. They are seen on an EEG by an increase in signal amplitude. Many things can cause arousals. Apnea, legmovements, and pain just to name a few. If this were my son I would check with my dentist to see if he is grinding his teeth. We see quite a bit of teethgrinding (bruxism) in this age group.
