OSA defintion
recurrent partial or complete airflow obstruction during sleep, intermittent hypoxia and sleep fragmentation
measure for OSA
apnoea hypoxia index
ap+hypop / total time asleep
normal 0-4
moderate 15-29
OSA symtoms
excessive daytime sleepiness with 2 +: choking decreased concentration recurrent awaking fatigue unrefreshing sleep
apnoea
decreased airflow of over 90% for at least 10 seconds
hypopnea
dressed airflow of over 30% for at least 10 seconds
pathophysiology of OSA
pharyngeal narrowing
negative thoracic pressure
increases BP
decreases sleep
epworth sleepiness score
0 to 10 = normal range of sleepiness in healthy adults.
11 to 14 = mild sleepiness.
15 to 17 = moderate sleepiness.
18 to 24 = severe sleepiness
2 quizzes in OSA
