Obstructive Sleep Apnoea

Written by Dr Andrew Lam

Diagnosis and Severity of OSA

OSA confirmed by sleep study by the apnoea hypopnoea index (AHI), which represents the number of apnoeas/hypopnoeas detected in 1 hour.

Diagnosis of OSA made if:

AHI > 15 in an asymptomatic patient

AHI > 5 in symptomatic patient

Mild OSA: AHI > 5 but < 15

Moderate OSA: AHI > 15 but < 30

Severe OSA: AHI > 30

Epworth Sleepiness Scale

In the following situations, how likely are you to fall asleep?

0 – No chance

1 – Slight chance

2 – Moderate chance

3 – High chance

Situation	Chance of Falling Asleep (0-3)
Sitting and Reading
Watching TV
Sitting inactive in a public place
As passenger in the car for an hour without break
Sitting and talking to someone
Sitting quietly after lunch without alcohol.
In a car, while stopped for a few minutes for traffic

0-7: Unlikely to be abnormally sleepy

8-9: Average amount of daytime sleepiness

10-15: May be excessively sleepy depending on the situation. Consider seeking medical attention

16-24: Excessively sleepy and should consider seeking medical attention.

STOP-BANG Questionnaire

Low Risk: Score 0-2

Intermediate Risk: Score 3-4

High Risk: Score 5-8

Complications

Cardiovascular: Hypertension, LV Failure/Hypertrophy, Myocardial Ischaemia, Arrhythmias.

Thought to be secondary to a combination of hypoxia/hypercapnia and episodes of sympathetic drive/oxidative stress associated with this.

Pulmonary: Pulmonary hypertension and subsequent right sided heart strain/failure. Thought to be due to reflexive pulmonary vasoconstriction during episodes of hypoxis

Neuropsychiatric: Decreased executive and cognitive function, mood disorders, psychosis, memory deficits
