Obstructive Sleep Apnoea

What is Obstructive Sleep Apnoea (OSA)?

If the muscles at the back of the throat relax too much the airway becomes completely blocked and breathing stops. This is called an “apnoea” which means “no air flow to the lungs”. Each time your airway blocks off your body may not get enough oxygen.

The apnoea (no air flow to the lungs) can last 10 seconds or more and can happen hundreds of times a night. During the apnoea, the brain soon recognises there is a problem and wakes the person up a little. The muscles then firm up which means the airway opens and breathing begins again.

As the person relaxes and becomes deeply asleep, further apnoeas will happen. This can significantly affect sleep quality.

Who gets OSA?

• Anyone.
• More males than females.
• Those who have nose or throat problems, i.e nasal polyps, large tonsils.
• Those with a small throat.
• Being overweight does not cause OSA, but will make the problem worse. 

What is the treatment for OSA?

Continuous Positive Airway Pressure (CPAP) machine is the usual treatment for OSA.

• A CPAP machine is a pump which delivers air to the lungs.
• The air travels from the machine through a tube to a mask on the nose.
• The air pressure supports the muscles at the back of the throat to keep them open during sleep.
• The CPAP machine is only used during sleep.
• The machine will stop you snoring and having apnoeas and improve your sleep quality.
• Daytime sleepiness should disappear.

Note

• CPAP is a treatment only.
• There is no cure for OSA.
• To be effective, CPAP must be used each time you sleep.

If you believe that you may have Obstructive Sleep Apnoea, ask your GP to refer you to a Sleep Clinic for assessment. You will have to complete a Sleep Questionnaire which will be sent to the Clinic.
