ANSWER- Cheyne 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.
According to guidelines, how many Hypopneas need to occur in peds pts
prior to 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
65 arousals
360 min of sleep - ANSWER- 11
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
