What is aerophagia? - ANS The swallowing of air
What is maxillomandibular advancement? - ANS Treatment that involves cutting and
advancing the upper and lower jaw bones; enlarging and stabilizing the posterior airway.

,What are the AASM guidelines for supplemental O2 during PAP studies? - ANS 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.

BiLevel should be used? - ANS IPAP: 14
EPAP: 10
Which of the following can reduce the effectiveness of CPAP and why: Nasal spray, Alcohol, Anti
depressants. - ANS 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? - ANS Overlap syndrome
What are hypoxemia and hypercapnia? - ANS 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? -
ANS Hypoventilation

fall asleep
Tricyclic antidepressants, large amounts of caffeine and large amounts of chocolate have been
known to trigger what? - ANS REM sleep behavior disorder

adult polysomnogram is - ANS Occurrence of hypoventilation during the diagnostic study in
adult
The respiratory event that requires oxygen desaturation and/ or an arousal as part of the
scoring criteria is - ANS 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 - ANS Atrial fibrillation

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? - ANS Provide the patient with educational material about
sleep apnea
Which of the following is the MOST LIKELY cause of a 35 minute REM latency - ANS Untreated
depression
A breathing pattern characterized by at least three cycles of crescendo breathing with duration
of at least 10 minutes is - ANS Cheyne Stokes respiration
An important responsibility of the scoring tech is to - ANS Confirm accuracy of report
components
Which type of calibration is based on a series of patient instructions intended to verify the
signal response and quality - ANS Physiological
The most important reason for performing a MWT is to - ANS Measure the patient's ability to
resist the urge to fall asleep
The importance of selecting sampling rates according to RECOMMENDED guidelines is to -
ANS Minimize aliasing effect
