Interview with Jiang Li, CEO at Vivalink

Vivalink announces a new cuffless blood pressure monitoring medical wearable. CEO and Founder Jiang Li discusses how blood pressure technology hasn’t changed much over the last few decades. Pressure monitoring testing is still being done in the old-fashioned way by recording patient vitals at intermittent, in-person visits with an inflatable cuff and with occasional at-home measurements. However, research has shown that 40% of patients are misdiagnosed. This can happen for various reasons – white coat syndrome for one. Patients often have heightened anxiety around doctors or in clinics, which can show increased blood pressure when day-to-day it is not an issue. But these visits can also show the opposite: blood pressure happens to be normal the day of that visit, when in fact there is an underlying issue. This results in patients either taking medications they don’t need or vice versa. Both scenarios can result in unwanted complications. These issues beg for a better solution and to bring a modern approach to blood pressure monitoring.

The first cuffless blood pressure technology was introduced in the 1980s, however, it is still in its infancy. The industry is pushing alternatives to medical wearable technology advancements that allow continuous heart monitoring and blood pressure. Vivalink has introduced and developed a unique wearable patch-based blood pressure device that is leveraging continuous ECG and mechanical signals instead of the traditional photoplethysmography. The use of these mechanical signals reduces the negative impacts from ambient lighting or high body mass index which are usually commonly experienced by PPG sensors.
