What Is Sleep Apnoea?
Obstructive sleep apnoea (OSA) is the name given to a condition when the airway collapses while you are asleep. The obstruction can be full or partial and restrict the amount of air that flows into the lungs.
Despite the person’s attempts to breathe, the airway will remain constricted. When this happens the person will change the position of their jaw and tongue, in order to re-open their airway. The person may snort or gasp for air. This is a cycle that may be repeated many times during the night. It may wake the person partially or fully, affecting your quality of sleep.
The effects of sleep apnoea can be harmful because it makes it more difficult to breathe.
An episode that lasts for 10 seconds or longer is considered clinically relevant. In some patients, apnoeaic episodes may last for as long as 30 to 60 seconds.
