asystole - CORRECT ANSWERS interruption of cardiac rhythm lasting
more than 3 seconds for ages 6 years through adulthood
AFIB - CORRECT ANSWERS irregular QRS complex associated with
replacement of consistent P waves by rapid oscillations that vary in size, shape,
and timing
Beta waves - CORRECT ANSWERS >13 Hz
central hypopnea - CORRECT ANSWERS respiratory event meet all
criteria for hypopnea with no snoring, increased inspiratory flattening of nasal
pressure or PAP device flow compared to baseline breathing, or associated
thoracoabdominal paradox occurs during event but not during pre-event
breathing
hypoventilation - CORRECT ANSWERS specified period of increased
PCO2 of 50 mmHg in children or >55 mmHg in adults, or rise of PCO2 during
sleep greater than or equal to 10 mmHg that exceeds 50 mmHg for specified
period of time in adults
scoring of hypopneas IN ADULTS - CORRECT ANSWERS score as
hypopnea if all criteria is met:
, a. peak signal excursions drop by greater than or equal to 30% of pre-event
baseline using nasal pressure, PAP device flow
b. duration of more than or equal to 30% drop in signal is more than or equal to
10 seconds
c. there is more than or equal to 3% or 4% oxygen desaturation from pre-event
baseline or event is associated with arousal
scoring of hypopneas IN CHILDREN - CORRECT ANSWERS score as
hypopnea if all criteria is met:
a. peak signal excursions drop by greater than or equal to 30% of pre-event
baseline using nasal pressure, PAP device flow
b. duration of more than or equal to 30% drop in signal excursions last for more
than or equal to 2 breaths
c. there is more than or equal to 3% oxygen desaturation from pre-event
baseline or event is associated with arousal
score hypopnea as obstructive if ANY of criteria are met (same for adults and
children) - CORRECT ANSWERS a. snoring during event
b. increased inspiratory flattening of nasal pressure or PAP device flow
compared to baseline breathing
c. there is associated thoracoabdominal paradox that occurs during event but not
during pre-event breathing
SCORE HYPOPNEA AS CENTRAL IF NONE OF THE FOLLOWING
ABOVE ARE MET
Cheyne-stokes breathing - CORRECT ANSWERS breathing rhythm
with specified crescendo and decrescendo change in breathing amplitude
separating central apneas or hypopneas
delta frequency - CORRECT ANSWERS 0-3.99 Hz
