Blood pressure monitor on the go with your phone

Optibp - blood pressure monitor - innovation in healthcare

Another tech company has published a new device/application in the field of blood pressure monitor. OptiBP lets you monitor blood pressure on the go with your phone – CNET. 

This story is part of CES, where our editors will bring you the latest news and the hottest gadgets of the entire virtual CES 2021.

It’s the start of CES 2021, one of the busiest weeks in the tech calendar, and I’m feeling pretty stressed. I take my blood pressure and no surprise, it’s higher than normal. But instead of using a traditional cuff, I’ve just measured it with an app on my phone.

Swiss startup Biospectal wants to replace the blood pressure cuff with its OptiBP app. It’s designed for people who CEO Eliott Jones calls “on-the-go hypertensives” or those with high blood pressure who have already been diagnosed by a doctor. Hypertension affects an estimated 1.13 billion people worldwide according to the World Health Organization.

The app works by using your phone camera and flash to measure blood flow in your finger, then uses algorithms to determine your pulse and ultimately, your blood pressure.

There’s no shortage of watches that can keep an eye on your blood-oxygen levels and even take an electrocardiogram (ECG or EKG) from your wrist, like the Apple Watch Series 6. Blood pressure is something that only a few watches, like Omron’s FDA-cleared HeartGuide, can measure. Samsung’s Galaxy Watch 3 also has this feature, but it’s not yet FDA cleared or active in the US. Omron has also announced its VitalSight platform at CES 2021 that can automatically send measurements from a cuff to your doctor.

But these devices are extra pieces of equipment you might not already own. Being able to take a quick reading on the go from the phone that’s already in your pocket could be a lot more convenient.

Before you take your first blood pressure reading you need to calibrate the app with a traditional blood pressure cuff. Jones says that this is the first and last time you’ll need to calibrate, unlike using a traditional cuff that requires more frequent calibration.

Place your finger over the camera lens to take a reading, but make sure you don’t obscure the LED flash.

Biospectal sent me a phone preloaded with the OptiBP beta and an Omron blood pressure cuff to test out the app. As it turns out, I must have pretty poor circulation in my fingers, as it took a little while for the phone to get a read on my pulse and to take a successful reading. Jones told me that warming my hands and rubbing them together would help. Once I got warmed up, I took a reading on the app, and reading on the blood pressure cuff the results lined up within five points of each other. We have not yet verified the accuracy of the app with a doctor yet.
