Lumia tracks blood flow to the head with Daniel Lee

Engineer and tech founder Daniel Lee has created the Lumia, a personal wearable device that fits in the ear to measure blood flow to the head, focusing on the external carotid artery, as a proxy for cerebral blood flow. This device is intended to help POTS patients track how different activities, foods, medications, and environmental factors affect their symptoms by showing blood flow changes. The Lumia has been validated in studies with notable academic centers like Johns Hopkins, Duke, and Harvard, demonstrating its sensitivity in detecting blood flow changes associated with orthostatic intolerance before traditional metrics like heart rate or blood pressure show abnormalities. While not yet FDA-approved for diagnostics, Lumia is available for self-management, providing insights into personal triggers for blood flow changes. Lee's research has shown that various factors such as body position, temperature, and diet can affect blood flow to the head, influencing POTS symptoms. As the product is still in beta, there are plans to expand availability and its diagnostic capabilities.
