CORRECTANSWER Cheyne Stokes and central Apneas have not been eliminated.
What is aerophagia? -CORRECTANSWER The swallowing of air
What is maxillomandibular advancement? -CORRECTANSWER Treatment that
involves cutting and advancing the upper and lower jaw bones; enlarging and stabilizing
the posterior airway.
What is the PRIMARY function of the EPAP setting? -CORRECTANSWER To eliminate
desaturations and arousals.
According to guidelines, how many Hypopneas need to occur in peds pts prior to
increasing pressure? -CORRECTANSWER 1
,What are the AASM guidelines for supplemental O2 during PAP studies? -
CORRECTANSWER 1lmp during PAP titration when SPO2 is less than or equal to 88%
for 5 or more minutes and in the absence of obstructive events.
If a pts Apneas are fixed at 10cm, but Hypopneas and snoring still occur at 16cm, what
levels of BiLevel should be used? -CORRECTANSWER IPAP: 14
EPAP: 10
Which of the following can reduce the effectiveness of CPAP and why: Nasal spray,
Alcohol, Anti depressants. -CORRECTANSWER Alcohol: impairs arousal response
which can lead to longer than normal events and severe desats. Inhibits upper airway
activity
What syndrome would a pt with COPD and OSA have? -CORRECTANSWER Overlap
syndrome
What are hypoxemia and hypercapnia? -CORRECTANSWER Hypoxemia: very low 02
in the blood
Hypercapnia: very high CO2 in the blood.
What would a patient with both hypoxemia and hypercapnia most likely be diagnosed
with? -CORRECTANSWER Hypoventilation
,What is an MWT's MOST important use? -CORRECTANSWER Measure patients ability
to resist the urge to fall asleep
Tricyclic antidepressants, large amounts of caffeine and large amounts of chocolate
have been known to trigger what? -CORRECTANSWER REM sleep behavior disorder
Recommended impedance for eeg and eog -CORRECTANSWER 5k ohms
The amount of space needed to archive digitized data is MOST impacted by? -
CORRECTANSWER Sampling rate
Cortical activity is best described as -CORRECTANSWER Spontaneous arousal
Calculate the AHI based on the following data
25 obstructive apneas
5 central apneas
23 mixed apneas
15 hypopneas
48 RERAS
65 arousals
360 min of sleep -CORRECTANSWER 11
, According to RECOMMENDED guidelines, the minimum duration of a significant leg
movement is -CORRECTANSWER .5

the scoring criteria is -CORRECTANSWER Obstructive hypopnea
An ECG arrhythmia commonly seen when recording PSG's, particularly in patients that
have obstructive sleep apnea and cardiac disease. It can be identified by the
morphology of an irregularly irregular ventricular rhythm associated with replacement of
consistent P waves by rapid oscillations that vary in size, shape, and timing -
CORRECTANSWER Atrial fibrillation
The stage that is the greatest portion of the epoch -CORRECTANSWER The stage that
is the greatest portion of the epoch
What is the best response when a patient asks the technologist if they have sleep
apnea and will need to wear a CPAP mask? -CORRECTANSWER Provide the patient
with educational material about sleep apnea
