This non-invasive test uses a small wearable sensor to track your blood oxygen levels continuously over 24 hours. It provides key data on how your body responds during sleep, daily activities, and moments when symptoms aren’t always felt. It’s an important investigation for identifying oxygen dips during sleep and diagnosing conditions such as sleep apnoea. It is also essential for distinguishing headaches caused by overnight oxygen desaturation from other types of headache, including migraine, cluster headache, tension-type headache, and others.
This service is especially useful in diagnosing subtle respiratory conditions, adjusting treatments, and managing long-term respiratory or cardiac concerns.
