A tool or device on a polysomnograph that sets a limitation to the high frequency signals that are allowed to pass through the amplifier.

Standard EEG setting is:

Filters 50 to 60 Hz activity.

If the vertical scale (sensitivity) is 8 uV/mm, then a 80 uV wave will measure:

HFF – “____ cut, _____ pass”

If the distance from Inion to Nasion is 47cm, what is the distance from Cz to Pz? _____

Question _____ is breathing that is seen when inhalation results in a decreasing, or asymmetrical, chest movement rather than normal chest expansion. This type of breathing causes poor ventilation of the lungs, carbon dioxide buildup and oxygen depletion in the blood.

During the machine cals the negative signal sent to the polygraph causes a ____ pen deflection.

The AASM recommends that amplifier calibration is to be performed.

A layer at the back of the eyeball containing cells thatâ s are sensitive to light and that trigger nerve impulses that pass via the optic nerve.
