How is snoring diagnosed?
Your doctor will ask questions to evaluate your snoring and perform a physical exam, paying careful attention to your throat, mouth, and neck. The doctor will listen to a description of the symptoms such as snoring, breaks in breathing during the night, sleepiness during the day. Pulse oximetry is used to measure the amount of oxygen in the blood and the pulse rate. The recording is taken for at least 8 hours overnight, and can be carried out at home. Multiple dips in oxygen level and peaks in pulse rate are found in people with sleep apnoea. Polysomnography, which involves many measures of sleep, includes eye movements and chin tone to define sleep stages, flow of air through the nose and mouth, movement of the chest wall, oxygen levels in the blood, and ECG (electrocardiography) to measure any serious abnormal heart rhythms.
