Pediatric Scoring
TIM A. STATZA
NOTE: This chapter corresponds to Chapter 44 in Fundamentals of Sleep Technology, 2nd edition.
1. In contrast to alpha rhythm in adults, the dominant posterior rhythm in infants is:
A. Slower
B. Faster
C. About the same
D. Sharp and spiky rather than smooth and sinusoidal
2. Stage N can be used in scoring NREM sleep in:
A. Infants without spindles, K complexes, or slow waves
B. Children without alpha rhythm activity
C. Children without vertex sharp waves
D. Infants without sawtooth waves
3. Hypnagogic hypersynchrony is:
A. A vivid visual phenomenon at sleep onset
B. Interictal activity
C. A pediatric equivalent of spindle activity
D. Bursts of theta waves during drowsiness
4. In infants less than 2 months of age, a distinctive EEG pattern associated with NREM or quiet sleep and consisting of high-voltage slow waves separated by 4 to 8 seconds of lower-voltage mixed frequency waves is called:
A. Burst suppression
B. Frontal intermittent rhythmic delta activity
C. Flat and wave activity
D. Trace alternant
5. The duration of an obstructive apnea in a pediatric patient is at least:
A. 10 seconds
B. 20 seconds
C. Two missed breaths
D. Long enough to cause a 3% oxygen desaturation
6. In children, central apneas lasting less than 20 seconds and not accompanied by a 3% oxygen desaturation or arousal are:
A. Scored as a hypopnea
B. Extremely rare
C. Normal
D. Scored as postarousal breathing pauses
7. CO2 monitoring, using either end-tidal or transcutaneous sensors, is mandatory in children for the scoring of:
A. Apnea
B. Hypopnea
C. Central events
D. Hypoventilation
