What is Obstructive Sleep Apnoea (OSA)?

Many people take a good night’s sleep for granted. They sleep peacefully through the night unaware that up to 10% of the adult population has their sleep disrupted by repeated episodes of upper airway collapse, known as Obstructive Sleep Apnea (OSA). Thankfully, OSA is a treatable condition.

Narrowing Airways
During sleep our muscles relax. The muscles in our throat, however, maintain some tone to hold our airway open for us to breathe. For some people these muscles relax too much. This can cause the airway to narrow slightly.

Snoring versus OSA
Partial airway narrowing will often result in snoring - a vibration generated by air passing the soft, floppy parts of the throat during breathing. However, sometimes the narrowing is more significant and causes a partial or complete reduction in airflow to the lungs. This condition is called Obstructive Sleep Apnea (OSA).


Blocked Airways
When the airway is blocked OSA sufferers will wake either partially or completely to breathe again. They are often unaware this even happens. This (apneas) can occur up to several hundred times a night, causing severe disruption to sleep and daytime sleepiness.

Untreated OSA may also lead to fatigue related road accidents and other serious health problems including high blood pressure, heart attack and stroke.The good news is that effective treatment is at hand!

Understanding OSA

Are you suffering from OSA?

1.  SNORING - Do you snore loudly (louder than talking or loud enough to

     be heard through closed doors)?

2.  TIRED - Do you often feel tired, fatigued, or sleepy during daytime?

3.  OBSERVED - Has anyone observed you stop breathing during your


4.  BLOOD PRESSURE - Do you have or are you being treated for high

     blood pressure?

5.  Body Mass Index (BMI) - more than 35kg/m2?

6.  NECK CIRCUMFERENCE - greater than 40cm (16in)?


If you answered 'Yes' to 3 or more of these questions, there is a high possibility that you might be suffering from OSA.
