scoring post arousal events

Postby dreamweaver333 » Wed Feb 17, 2016 12:36 pm

Is there a new rule for scoring resp events regarding post arousals? In other words - no event if it occurs after a scoreable EEG arousal?

What are the rules concerning k-complex associated arousals? do you score every arousal after a k-complex?

No such thing as K arousal.
If an event abides by the definition and exclusion rules, score it.

Yep.

If it looks like a duck, sounds like a duck and smells like a duck, score it.

K-complexes can be followed by an arousal, but in the AASM world it doesn't matter if there's a K-complex or not. If there's 3 seconds of alpha (or an abrupt increase in EEG frequency etc) then mark it.

You should ONLY be looking at one hemisphere (the other is backup only) and then you should accrue "alpha time" across those channels the rules state. Similarly for SWA accrual. People love to accrue SWA across both frontals which is incorrect, as is incorrect to do so across both occipitals and centrals for alpha. Stay in Right hemisphere primarily and left hemisphere as backup...if right electrode goes bad use homologous lead from left hemisphere.
