|
What's the optimal paper speed for a polysomnograph
|
30 Seconds per page or 10 mm/sec
|
|
|
What is a montage
|
The defined arrangement of channels and signal derivations on a PSG
|
|
|
An EEG arousal is a shift in EEG frequency lasting how long
|
3 seconds
|
|
|
EEG'S are also beneficial in detecting
|
seizure activity and beta spindles
|
|
|
What is a referential montage
|
A montage that utilizes common electrodes as references for the exploring electrodes
|
|
|
What is a bipolar montage
|
A channel set-up based on recordings from two exploring electrodes
|
|
|
What PSG channels are direct current
|
Body position, PAP
|
|
|
ECG artifact is often seen in patients with
|
Hypertension
|
|
|
ECG artifact is commonly seen in which channels
|
EOG, Chin and leg EMG
|
|
|
What is double referencing
|
Using cables (Jumper) to connect two reference leads to each other in order to decrease or eliminate artifact
|
|
|
Using Jumper Cables means
|
your M channel is changed to M+ and you cannot rereference it
|
|
|
Sweat artifact
|
A slow wave artifact caused by excessive sweat from the patient
|
|
|
Sweat artifact is often called
|
Slow wave artifact or sway artifact
|
|
|
Are slow wave artifacts all caused by perspiration
|
No
|
|
|
What are some other examples of slow wave artifact
|
Slow head movements associated w/ breathing
|
|
|
Sweat artifact can be masked by increasing the
|
Low frequency Filter
|
|
|
Is Snore artifact correctable by changing filter or gain settings?
|
No
|
|
|
What is Electrical Noise
|
Also Known as 60Hz artifact, is high frequency in the 59-61Hz range derived from outside electrical activity.
|
|
|
Can 60Hz artifact be present when all connections are stable?
|
Yes
|
|
|
What is a 60Hz filter
|
Also Known as a notch or line filter, is a specialized frequency filter used for a small range of frequencies from 50-60Hz. It helps Eliminate AC line frequency interference
|
|
|
Electrode Popping
|
An artifact characterized by occasional brief bursts of 60-Hz activity
|
|
|
What is the gain setting
|
Sensitivity controller of the amplifier
|
|
|
What is the sensitivity setting
|
A setting on the PSG that adjusts height
|
|
|
improper gain/sensitivity setting can
|
diminish the quality of the channel and impede the scorers ability to score the study
|
|
|
Gain does not increase the _______ of the wave
|
Amplitude
|
|
|
Filters should ________used to correct artifact
|
not be
|
|
|
Alternative treatments for OSA other than CPAP include
|
Pillar implants, Dental appliances, specialized pillows, throat lubricant, snore strips, and surgeries
|
|
|
To reduce airway dryness, CPAP machines come with
|
humidification
|
|
|
What does titration mean
|
The gradual process of adjusting the strength or dose of a medication or treatment until optimal treatment is reached
|
|
|
What is the criteria for optimal CPAP titration
|
Respiratory Disturbance Index (RDI) < 5 events/ hour
SpO2> 90% EEG arousals < 5/hour Snoring Eliminated |
|
|
What device verifies PAP levels
|
Water Column Manometer
|
|
|
What is A.W.A.K.E
|
A CPAP support group that helps patients get comfortable with their masks, insurance issues, and CPAP compliance
|
|
|
CPAP is increased for what reasons
|
OA's, Hypopneas, snoring, arousals, RERAs, Desats
|
|
|
What are some reasons for decreasing CPAP
|
Central Apneas
|
|
|
What are some reasons to switch to Bi PAP
|
To treat CSA and increase tolerance to PAP
|
|
|
CSA's are caused by
|
Hypocapneas
|
|
|
Supplemental Oxygen
|
Additional oxygen delivered to a patient via nasal cannula
|
