Illustration of a cross-section through the upper respiratory tract of a patient with sleep apnoea. Sleep apnoea is a lack of oxygen caused by a patient's muscles relaxing and restricting the airways during sleep. It results in interrupted breathing that frequently wakes the patient and is a cause of snoring. Sleep apnoea is treated by the patient wearing a continuous positive airway pressure (CPAP) device while sleeping to maintain the airway. | |
