What is Sleep Apnoea, Are you at Risk?
An obstruction can last up to 2 minutes and may occur several hundred times during a nights sleep. Although the sufferer is unaware, the brain recognises low levels of oxygen during these episodes and alerts the body to wake and take a breath.
These episodes may occur hundreds of times during the night. The sufferer is not fully roused by these events and in the morning will be unaware of any disturbances to their sleep.
The brief wake-ups that people with OSA experience diminishes their quality of sleep, resulting in sleep deprivation. The symptoms of sleep deprivation may be what bring most people with OSA to see their physician.
Normally during sleep, the muscles which control the tongue and soft palate hold the airway open.
Healthy upper airway
If these muscles relax, the airway narrows, causing snoring and breathing difficulties.
Partially obstructed upper airway
If these muscles relax too much, the airway can become completely blocked, preventing breathing.
Obstructed upper airway
