identical voltages from two different sources (records dissimilar voltages)
(higher the CMMR, the more efficient the amplifier)

What happens to a waveform is sensitivity is increased? - Answer- The vertical size of the wave decreases
what is the difference in gain and sensitivity? - Answer- Increasing gain increases amplitude and
increasing sensitivity decreases the amplitude
What is the shortest sleep latency for a MSLT nap? - Answer- 15 minutes (longest its 35 minutes)
What is HST? - Answer- Home sleep test
How do you clean ECG electrodes? - Answer- Wipe with cleaning agent that is non-corrosive to plastic,

downward deflection
if looking right, REOG has downward deflection and LEOG has upward deflection
What is needed to score REM Without Atonia (RWA)? - Answer- Excessive sustained muscle activity in
REM and cEMG
Excessive TMA in REM and chin or limb EMG
50% of mini epochs contain any chin or limb activity
What is a normal PR interval? - Answer- 0.20 seconds
What is the Respiratory Event Index equation? - Answer- REI= (# of apneas + hypopneas) x 60 /
monitoring time
When active equipment is close to patient what kind of artifact occurs? - Answer- 60 Hz artifact
(can also occur from poor electrode contact, defective wires, inadequate grounding, and it's see in
EEG/ECG/EOG/EMG)
