A patient being evaluated for obstructive sleep disordered breathing has atrial
fibrillation. What should the tech do - answers - continue to observe and document
rhythm

block
What is the most likely low frequency filter setting of channel 1 - answers - 1.0 hz
Which channel setting is best for emg recording - answers - 2 chan 2 has a very quich
return to baseline, (very short time constat)
Refer to the 30 second epoch shown here. If the next epoch contains 30 seconds of low
voltage, mixed frequency in the 4-7 hz range, and no eye movements, what is the sleep
stage of that next epoch? - answers - stage n1 the epoch shown contains a k complex,
