what is the minimum number of diagnostic and therapeutic in a split study?
- ANSWER- 2 diagnostic 3 therapeutic
what is the most stable stage of sleep respiratory wise? - ANSWER- N3 (NREM
is more stable and REM is irregular)
What does common mode rejection do? - ANSWER- It is a process that takes
input signals and eliminates identical voltages from two different sources (records
dissimilar voltages)
(higher the CMMR, the more efficient the amplifier)
what should the low pass filter for an EEG be if seizures are expected?
- ANSWER- 70 Hz (usually 35 Hz)
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
