Sleep Study results are in

And...

Sam has sleep apnea.  Matt talked to the doctor, which is never good because he doesn't know what questions to ask.  Plus Matt is an extreme introvert, so he just tries to get off the phone as soon as possible.  I am going to call over there in the morning to get some more answers.

I need to know...

1. Do they think he has obstructive or central apnea?  Or both?
2. How severe is the apnea?
3. When they told Matt that Sam needs oxygen when he's sleeping, did they mean a CPAP or a canula?  At first I thought it was a CPAP, but the way Matt said oxygen and had no idea what CPAP meant as well as they way they said just oxygen and told us to set up delivery with our pediatrician...makes me think canula.  From what I understand, to get a CPAP, you need to schedule a second sleep study.  
4. Are there other measures we can take to decrease his apnea?  Should we be looking at removing his adenoids and tonsils?

And for fun...here's a video of Sammy with his favorite toy.
