Lumia tracks blood flow to the head with Daniel Lee

In this episode of POTScast, Jill Brook interviews Daniel Lee, the engineer and founder who developed the Lumia device. Lumia is a wearable device designed to measure blood flow to the head by fitting inside the ear, specifically targeting the external carotid artery. This measurement acts as a proxy for cerebral blood flow, offering insights into conditions like POTS, where traditional measures such as blood pressure and heart rate might not indicate abnormalities. Lee shares that Lumia has been validated through research collaborations with major academic centers such as Harvard and Johns Hopkins, showing strong correlations with established blood flow measurement methods. The device is intended to help POTS patients understand personal triggers and improve symptom management by tracking flow changes associated with different activities, foods, and environmental factors. While not yet an FDA-approved diagnostic tool, it currently functions as a self-management device in a beta program available to patients in the United States, highlighting the importance of nonpharmacological approaches in managing POTS symptoms.
