SLEEP COURSE 2022

1.      How many hours of recording time is considered acceptable in Type III recording device given adequate flow and oximetry signals?

• 3 Hours

• 2 Hours

• 4 Hours

• 6 Hours

2.     Which the following is not a chin EMG?

• Mentalis

• Submentalis

• Masseter

• Extensor Digitalis

3. Both thermistor and thermocouple measure airflow based of which of the following:

• Temperature differential of inhale and exhale air

• Detecting changes in pressure between inhalation and exhalation

• Contour of the airflow wave from recording

• Difference between the inspiratory and expiratory airflow rate

Low amplitude mixed frequency EEG waves are predominantly seen in the

• Frontal region

• Central region

• Temporal region

• Occipital region

Which of the following do we spend the least amount of sleep?

• Stage N1

• Stage N2

• Stage N3

• Stage R

Which sleep stage will you not see theta waves?

• Stage N1

• Stage N2

• Stage N3

• Stage R

A well-delineated negative-sharp wave followed by a positive component and lasting at least 0.5 sec in duration is called:

• Vertex sharp wave

• K-complex

• Delta waves

• Paroxysmal burst

Which sleep stage will you not see sleep spindles?

• Stage N1

• Stage N2

• Stage N3

• Stage R

Cessation of nasal/oral airflow, nasal pressure and respiratory efforts followed by resumption of respiratory efforts with continued cessation of nasal/oral airflow and nasal pressure would be scored as:

• Central apnea

• Obstructive apnea

• Mixed apnea

• Hypopnea

Five consecutive cycle of crescendo-decrescendo central event would be classified as:

• Central apnea

• Mixed apnea

• Cheyne-Stokes breathing

• Paradoxical breathing
