| Sleep Apnea Definitions (snoredog and rested gal) (The Absolute Basics) |
|---|
DEFINITIONS from snoredog:
APNEA = cessation of airflow for 10 seconds or greater.
HYPOPNEA =>50% decrease in airflow for 10 seconds or greater with a decrease in oxygen saturation of >3%.
APNEA/HYPOPNEA INDEX (AHI) = apnea plus (+) HYPOPNEA/hour of sleep.
RESPIRATORY AROUSAL INDEX (RAI) = AHI +snoring related EEG arousals/hour of sleep.
AHI/RAI** Scale =<5 events /hour = (none); 5-15 events/hour = (mild); 15-30 events/hour = (moderate); >30 events/hour = (severe).
Respiratory related sleep fragmentation: Sleep arousals due to respiratory events or snoring.
Desaturation = Drop in O2 oximetry distribution saturation by 3% below average saturation.
SaO2 scale: >89%=(none); 85-89%=(mild);80-84%=(moderate); <80% (severe).
EPWORTH SLEEPINESS SCALE =<10=(does not indicate EDS (Excessive Daytime Somnolence));10-15=(indicates daytime somnolence-not excessive);>16 (indicates EDS).
RESPIRATORY EFFORT RELATED AROUSALS (RERAs)=Sleep Arousals due to respiratory events characterized by pressure flow limitations in the airflow indicator channel without significant O2 desaturations.
StageIII and StageIV are combined and referred to as Deep Sleep.
Sleep Efficiency = Normal is >80%
