Comparing Accuracy Between Cuffless Wrist Worn and Cuffed Ambulatory BP Monitoring Devices

Wrist worn devices can help record Blood Pressure (BP) throughout the day. As such devices are becoming increasingly affordable, they could help improve awareness, early diagnosis, and treatment of high and uncontrolled BP. The goal of Continuum BP is to evaluate how BP readings from two different types of wrist-worn cuffless devices available on the market (Aktiia and Healthstats BPro Evo) compare with BP taken using an ambulatory BP monitor which records readings over 24h using a standard upper arm cuff. This interventional study will recruit balanced numbers of male and female participants within different age group, who will sequentially wear the Aktiia Bracelet and the Heathstats BPro Evo for a period of 24h, alongside the cuffed ambulatory BP monitor. If wrist worn devices are found to measure BP reliably, future research will assess if artificial intelligence can use continuous BP readings from these devices to learn patterns and changes in BP; and develop digital twin models to guide better, more precise BP management for individuals.
