Seems a bit of a stretch to assume the guy has _sleep apnea_ if he nods off during a likely pointless meeting. If he's passing out at his desk, then perhaps.
I assume nothing. Sleep apnea is simply one of the most common sleep disorders, and one of the easiest to treat, so it makes sense to test it out first. The sleep study required to do so will also reveal most other sleep problems that are not caused by apneas.
Falling asleep involuntarily in the middle of the day is not normal, regardless of the circumstances. Sleep problems can lead to heart problems, and preventable deaths.
