Stokes and central Apneas have not been eliminated.
What is aerophagia? - ANSWER-The swallowing of air
What is maxillomandibular advancement? - ANSWER-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? - ANSWER-To eliminate
desaturations and arousals.

increasing pressure? - ANSWER-1
What are the AASM guidelines for supplemental O2 during PAP studies? - ANSWER-
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? - ANSWER-IPAP: 14
EPAP: 10
,Which of the following can reduce the effectiveness of CPAP and why: Nasal spray,
Alcohol, Anti depressants. - ANSWER-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? - ANSWER-Overlap syndrome
What are hypoxemia and hypercapnia? - ANSWER-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? - ANSWER-Hypoventilation
What is an MWT's MOST important use? - ANSWER-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? - ANSWER-REM sleep behavior disorder
Recommended impedance for eeg and eog - ANSWER-5k ohms
The amount of space needed to archive digitized data is MOST impacted by? -
ANSWER-Sampling rate
Cortical activity is best described as - ANSWER-Spontaneous arousal
Calculate the AHI based on the following data
25 obstructive apneas
5 central apneas
23 mixed apneas
15 hypopneas
48 RERAS

According to RECOMMENDED guidelines, the minimum duration of a significant leg
movement is - ANSWER-.5
According to RECOMMENDED guidelines, an optional parameter to include in the report
for an adult polysomnogram is - ANSWER-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 - ANSWER-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 - ANSWER-Atrial
fibrillation
The stage that is the greatest portion of the epoch - ANSWER-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? - ANSWER-Provide the patient with educational
material about sleep apnea
Which of the following is the MOST LIKELY cause of a 35 minute REM latency -
ANSWER-Untreated depression
A breathing pattern characterized by at least three cycles of crescendo breathing with
duration of at least 10 minutes is - ANSWER-Cheyne Stokes respiration
An important responsibility of the scoring tech is to - ANSWER-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 - ANSWER-Physiological
The most important reason for performing a MWT is to - ANSWER-Measure the patient's
ability to resist the urge to fall asleep
The importance of selecting sampling rates according to RECOMMENDED guidelines is
to - ANSWER-Minimize aliasing effect
The syndrome characterized by prolonged episodes of severe hypoxemia and associated
PaCO2 elevation that worsens during sleep is - ANSWER-Obesity hypoventilation
The patient's medical history indicates the patient has been taking tricyclic
antidepressants for the past 5 years. The technologist should anticipate that the patient
may have an increased likelihood of - ANSWER-REM Sleep Behavior Disorder
According to RECOMMENDED guidelines, the sampling rate to provide the optimal
resolution for recording EEG in a patient with suspected nocturnal seizure is -
ANSWER-500Hz
The electrode located 30% above the left pre-a crease is - ANSWER-C3
According to RECOMMENDED guidelines, four nap opportunities on a MSLT would be
acceptable when the patient - ANSWER-Had REM on at least two nap opportunities
A patient's history indicates a diagnosis of overlap syndrome. The tech can anticipate
that the patient has - ANSWER-COPD AND OSA
ACCORDING TO RECOMMENDED GUIDELINES, WHICH OF THE FOLLOWING SHOULD
BE INCLUDED WHEN RECORDING PEDIATRIC PATIENTS - ANSWER-END-TIDAL CO2
THE ABILITY TO REMONTAGE WHILE RECORDING ON DIGITAL EQUIPMENT IS THE
RESULT OF - ANSWER-SYSTEM REFERENCING
