Disorders, AASM Guidelines.
The purpose of an intentional mask leak is to...
Wash out CO2 and prevent rebreathing
Recommended guidelines state that HSV can be considered when....
Cheyne Stokes and central Apneas have not been eliminated.
What is aerophagia?
The swallowing of air
What is maxillomandibular advancement?
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?
To eliminate desaturations and arousals.
According to guidelines, how many Hypopneas need to occur in peds pts prior to increasing
pressure?
1
What are the AASM guidelines for supplemental O2 during PAP studies?
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?
IPAP: 14
EPAP: 10
Which of the following can reduce the effectiveness of CPAP and why: Nasal spray, Alcohol, Anti
depressants.
,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?
Overlap syndrome
What are hypoxemia and hypercapnia?
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?
Hypoventilation
What is an MWT's MOST important use?
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?
REM sleep behavior disorder
Recommended impedance for eeg and eog
5k ohms
The amount of space needed to archive digitized data is MOST impacted by?
Sampling rate
Cortical activity is best described as
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
11
, According to RECOMMENDED guidelines, the minimum duration of a significant leg movement
is
.5
According to RECOMMENDED guidelines, an optional parameter to include in the report for an
adult polysomnogram is
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
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
Atrial fibrillation
The stage that is the greatest portion of the epoch
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?
Provide the patient with educational material about sleep apnea
Which of the following is the MOST LIKELY cause of a 35 minute REM latency
Untreated depression
A breathing pattern characterized by at least three cycles of crescendo breathing with duration
of at least 10 minutes is
Cheyne Stokes respiration
An important responsibility of the scoring tech is to
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
Physiological
