RPSGT Study Guide Questions
with Correct Answers (VERIFIED)
RERA—ANSWER--Respiratory effort-related arousal
Score a RERA when—ANSWER--1. Breathing for at least 10 seconds shows increasing RIP
amplitudes or flattening of the nasal pressure signal followed by an arousal
2. The event is not an apnea or hypopneas
Hypoventilation is scored when—ANSWER--1. End-tidal CO2 or transuctaneous CO2 rises 10
mmHG above the level recorded with patient awake and lying down
2. Low oxygen desaturation is not enough to score hypoventilation
Score Cheyne Stokes breathing when—ANSWER--There are at least 3 cycles of rising and
falling breathing amplitude and at least 1 of the following:
1. 5 or more central apneas/hr of sleep
2. The rising and falling pattern lasts at least 10 min
EEG Arousal—ANSWER---An abrupt shift in EEG frequency, which may include theta, alpha,
or frequencies > than 16 HZ but not spindles, that lasts for 3 or more secs.
-Must follow at least 10 secs of sleep
-Arousals may be scored from either central or occipital channels
, Arousals in REM require an increased in—ANSWER--Chin tone
Physiological changes that may accompany Arousals—ANSWER---Increased in EEG frequency
-K complex followed by a shift in EEG frequency
-Increased in chin tone
-Hypernea
-Increase in heart rate
-Eye blinks
-Evidence of body movement
-Electrode popping
Hypernea—ANSWER--Increases in breathing rate or volume
Score a hypopnea when(1)—ANSWER--1. The nasal pressure amplitude drops by at least
30% of baseline
2. The duration of the drop is at least 10 secs.
3. There is at least a 4% desaturation
4. At least 90% of the event duration meets the amplitude criteria
Score a hypopnea when (2)—ANSWER--1. The nasal pressure amplitude drops by at least
50% of baseline
2. The duration of the drop is at least 10 secs
3. There is at least a 3% desaturation or an arousal
