Valencell Expands Worlds First Calibration-Free, Cuffless Blood Pressure Monitoring System to the Finger and Wrist

Valencell, a leader in transforming the science of wearable biometrics to enable impactful health outcomes, announced its groundbreaking calibration-free, cuffless blood pressure (BP) technology for wearables is now able to be used in devices worn on the finger and wrist. The technology, which brings cuff-like BP accuracy to other parts of the body, was first announced in January 2020 for hearables, hearing aids and other ear-based devices. This latest advancement significantly expands the number of device form factors to embed the technology, including smartwatches, fitness bands, patches and pulse oximeter finger clips.

According to the CDC 1, hypertension affects nearly one-third of Americans, or 75 million people, aged 18 or older. Additionally, for approximately one-half of adults with hypertension (nearly 35 million people), it is uncontrolled. A new national survey released today by Valencell revealed 62% of Americans with hypertension only measure their BP a few times a month or less, far below expert recommendations of twice daily 2 . However, more than 75% of respondents would measure their BP “more or much more” often if they could accurately measure passively in the background, which cuff-less options like smartwatches and audio earbuds would enable.

Valencell’s BP technology that can be built into a range of passive form-factors worn in the ear, on the finger and on the wrist makes it significantly easier for people to monitor their BP on a regular basis, allowing them to build potentially life-saving habits. Valencell is pursuing FDA clearance for this technology in early 2021 to help manufacturers who embed the technology in their devices moving forward with the clearance process

Unlike other sensor modalities such as ECG or pulse transit time, the Valencell BP technology does not need to be calibrated to a BP cuff and only requires data from photoplethysmography (PPG) and inertial sensors that are already in widespread use in wearables today. This data, along with a subject’s physical characteristics (age, weight, gender, height), is processed by the Valencell BP estimation software in an embedded model created using machine learning techniques and data from tens-of-thousands of patient results. Valencell is now the first commercially available embedded sensor solution to enable BP readings throughout the day with the same accuracy as current BP cuff devices without the need for a cumbersome cuff.

“Our survey results solidify the next frontier in medical wearables, which is to make a measurable impact on the global hypertension crisis through passive technologies that people will actually use regularly,” said Dr. Steven LeBoeuf, President and co-founder of Valencell.“Huge opportunities exist to ease the burden of blood pressure monitoring and reduce the cost of healthcare with non-invasive sensor technology embedded in devices people wear every day. In fact, the marketplace has recently validated the importance of regular BP self-monitoring with two new CPT codes—99473 and 99474 – supporting reimbursement for home BP monitoring.”

The full results of Valencell’s survey can be found here. Highlights include:

Inconsistent monitoring: People with high blood pressure are not measuring often enough. In fact, Americans with hypertension measure their BP “a few times a month” (31%) or “a few times a year” (also 31%). Only 4% measure BP multiple times a day.
Fingers and wrists: When provided a choice, respondents would prefer to passively measure their BP with a finger clip or pulse oximeter clip (41%), followed by a watch (40%), phone (32%), fitness band (20%) and earbuds (10%).
Information desired: In terms of data people would be interested in receiving when monitoring their BP, over half of respondents (52%) are interested in knowing if their blood pressure is out of the normal range or trending too high or too low. Forty-five percent are interested in the specific systolic and diastolic BP readings.
Comorbidities impact hypertension management: Numerous comorbidities emerged from the research in addition to hypertension, including high cholesterol (50%), obesity (42%), type 2 diabetes (27%), chronic kidney disease (7%) and congestive heart failure (5%).

Survey Methodology

The 2020 Blood Pressure Research Survey was conducted by Valencell from November 5-9, 2020. The online survey polled 787 U.S consumers, ages 18 and up, to understand how they manage hypertension and how that experience could be improved.
