Sleep disordered breathing involves a reduction in the airway space during sleep. Signs include loud snoring, choking or gasping for air during sleep, frequently awakening through the night, restless sleep, and excessive daytime sleepiness.
Snoring is caused by a partial closure of the airway space, resulting in the air to move faster during respiration causing soft tissue vibration which causes the noise.
Sleep Apnoea is where total airway closure occurs and the person stops breathing completely which will result in an awakening in the sleep pattern.
