BRPT QUESTIONS AND ANSWERS
The purpose of an intentional mask leak is to...: wash out co2 and prevent rebreathing
1. Recommended guidelines state that hsv can be considered when....: cheyne
stokes and central apneas have not been eliminated.
2. What is aerophagia?: the swallowing of air
3. What is maxillomandibular advancement?: treatment that involves cutting and advancing the
upper and lower jaw bones; enlarging and stabilizing the posterior airway.
4. What is the primary function of the epap setting?: to eliminate desaturations and arousals.
5. According to guidelines, how many hypopneas need to occur in peds pts prior
to increasing pressure?: 1
6. 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.
7. 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
8. 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
9. What syndrome would a pt with copd and osa have?: overlap syndrome
10. What are hypoxemia and hypercapnia?: hypoxemia: very low 02 in the blood
hypercapnia: very high co2 in the blood.
11. What would a patient with both hypoxemia and hypercapnia most likely be
diagnosed with?: hypoventilation
12. What is an mwt's most important use?: measure patients ability to resist the urge to fall asleep

by?: sampling rate

the report for an adult polysomnogram is: occurrence of hypoventilation during the diagnostic
study in adult
20. The respiratory event that requires oxygen desaturation and/ or an arousal
as part of the scoring criteria is: obstructive hypopnea
21. 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

sleep apnea and will need to wear a cpap mask?: provide the patient with educational material
about sleep apnea
