12 hours asleep
1 daytime nap
what gold standard test is used to assess sleep pattern?
polysomnography
describe what is involved in a polysomnography study (5)
O2 saturation (pulse oximetry) ECG EMG - electromyography - nerve and muscle cell function Abdominal wall movement oronasal flow
what is considered ‘abnormal’ sleep behaviour in a 1 year old?
if they sleep 8 hours at night and don’t nap throughout the day
what are some normal childhood sleep behaviours
sleep walking
sleep terrors
hypnic jerks
obstructive sleep apnoea in children
most common in pre- school children

respiratory disorders in children
Chronic neonatal lung disease - hypoxaemia in REM sleep (similar COPD)

FEV1 30-60%
Asthma
neurological disorders related to sleep apnoea in children
cerebral palsy
down syndrome
prader-willi syndrome- excessive daytime sleepiness

Newborns sleep pattern?

Dreams typically happen during REM sleep
which age group of children have highly efficient sleep?
prepubertal
other than polysomnography what other methods of sleep assessment are there for children? (4)
Direct behavioural observation
Time-lapse video
Movement sensors in cot mattress
Oxygen/CO2 monitoring
what normal phenomena are there in children?
sleep walking
sleep terrors
hypnic jerks
primary snoring?
snoring without apnea, hypoventilation, hypoxia, hypercarbia, daytime symptoms
10% prevalence
