|
What is the recommended HFF setting for EOG channels? |
35Hz |
|
|
What is the recommended sampling rate for EEG's, EOG's, EKG's, and EMG's? |
500Hz |
|
|
What is the recommended LFF for EEG channels? |
0.3Hz |
|
|
What is the recommended LFF setting for the SpO2 channel? |
The SpO2 channel is a DC channel. Therefore, no filters are set for this channel. |
|
|
What channel types are typically included in an MSLT montage, unless otherwise indicated? |
EEG, EOG, Chin EMG, and EKG |
|
|
What additional channels are typically included when performing a REM Behavior Disorder Study? |
Arm EMG channels to detect arm movements. Additional EEG channels are also sometimes recommended to rule out seizures. |
|
|
When looking at a calibration wave, what is the rise time? |
The amount of time it takes for the wave to travel from its baseline to 63% of its peak. This is usually measured in hundredths of a second. |
|
|
What filter directly impacts the Fall Time? |
The Low Frequency Filter |
|
|
What is the Time Constant? |
The amount of time for a calibration wave to fall from its highest point, or peak, to 37% of the peak |
|
|
Increasing the sensitivity setting from 10uV/mm to 20uV/mm will do what to the appearance of the wave? |
It will cut the height of the wave in half. |
|
|
What is the difference between the mechanical baseline and the electrical baseline? |
The mechanical baseline is the vertical positioning of the pen when the power is turned off. The electrical baseline refers to the same positioning when the power is turned on. |
|
|
What is the main difference between a Baseline/Diagnostic Montage and a CPAP Montage? |
A CPAP Montage includes additional channels for CPAP flow, pressure, and leak. |
