Accuracy of Cuffless Ambulatory Blood Pressure Monitors Compared to Cuff-based Monitors in an Ambulatory Elderly Population: A Pilot Study

The Aktiia device is a wearable blood pressure monitor developed by the company Aktiia SA. It is designed to monitor at blood pressure frequent intervals throughout the day and night without the need for inflatable cuffs. Instead, it contains optical sensors which collect photoplethysmography signals from arteries in the patient's wrist and uses these to estimate blood pressure. The device only takes measurements when it perceived optimal conditions for doing so, corresponding to minimal arm movement (i.e. a resting state) for at least five minutes and good quality signal detection. This device is commercially available and validated for use in adults aged 85 and younger.
