Scoring Rules
To score an arousal, it must last for at least _____ seconds.
3
The P wave represents:
Atrial depolarization
What is the generic name for Benadryl?
Diphenhydramine
a 90% drop in airflow with continued respiratory effort lasting at least 10 seconds.
Obstructive apnea
When measuring respiratory event desaturations, start at the nadir preceding the first breath that is reduced?
True
Central apneas are scored when:
There is a decrease in the thermistor with absence of respiratory effort.
Landmark waveforms for stage REM are:
Sawtooth
The definition of viscous is:
Sticky
True or False: In the definition of a central apnea, there is a continuation of the effort throughout the entire event
False
The minimal number of limb movements required to qualify as a PLM series is:
4
Ture or False: I have read and studied the entire AASM ISR Scoring Manual.
False
The rhythm seen most often during wake with eyes closed in the occipital region is:
Alpha
The Circadian Rhythm oscillates every _____ .
90 Minutes
What is the most common form of sleep apnea seen in the lab?
Hypopneas
An irregular R-R interval with P waves preceding each QRS narrow complex with a rate of 60-100 BPM:
Sinus Arrhythmia
In an epoch w/14 seconds of sleep, 10 seconds of stage N1 and 6 seconds of stage N2, you would score this epoch:
The QRS represents:
Ventricular repolarization
The portion of the brain that controls the Circadian Rhythm is:
SCN - Suprachiasmatic Nucleus
What is Treatment-emergent central sleep apnea
also known as complex sleep apnea, which happens when someone has OSA — diagnosed with a sleep study — that converts to CSA when receiving therapy for OSA
AASM Accreditation requires how many restrooms in the sleep lab?
One for every three patients.
AASM Rule 1A of scoring hypopneas include:
a) greater than 3% desaturation
b) the duration is greater than or equal to 10 seconds
c) all the above
Waveforms that occur in stages N1, N2, and REM with a frequency of 4-7 Hz are:
Low amplitude, mixed frequency (theta) waves
The chemical responsible for brain arousals is:
Dopamine
Which criteria must be met in order to score Cheyne-Stokes breathing?
A minimum of 5 central apneas or hypopneas per hour for 2 hours.
The frequency activity in which brain region is associated with hippocampal memory storage & retrieval?
Frontal Midline
