What is Respiratory Effort-Related Arousal (RERA)?
- Correct Answer - an arousal associated with increasing negative
esophageal pressure which is terminated by a sudden change in
pressure to a less negative level with an arousal; lasts 10 seconds or
longer
how many rounds of RERA per hour are considered abnormal and in
association with other symptoms are sufficient to produce a diagnosis of
OSA syndrome?
- Correct Answer - five or more
What is the Apnea Hypopnea Index (AHI)?
- Correct Answer - all the apneic episodes together with all the hypopnea
episodes occurring during the night and then dividing the total by the
number of hours slept

,- Correct Answer - It produces cardiac effects and disrupts sleep, leading
to the development of excessive sleepiness during the day
what are the typical etiology/pathophysiological factors in OSA?
- Correct Answer - tissue volume
changes in adhesive character of mucosal volume surfaces
changes in neck and jaw posture
decreased tracheal tug
effects of gravity
decreased intraluminal pressure from increased upstream resistance in
the nasal cavity or pharynx
