Sky Labs ring for blood pressure monitoring – Picture of the Day

The company states CART BP’s photoplethysmography (PPG) signals from its four sensors provide more reliable measurements than wrist-based devices.

Apparently, there are multiple ring sizes for a customised fit, and the device provides very accurate blood flow measurements through the finger. Wrist-based devices, they say, can struggle with accuracy due to variations in wrist size and sensor positioning.

The basic idea is for constant, unobtrusive monitoring, for data through both day and night…

AI

Almost inevitably there is AI in the equation. The sensor data it collects is subject to AI-based algorithms for detecting indicators of hypertension, recognising clinically meaningful changes.

The “deep learning algorithm” used blood pressure data gathered from a total of 4,185 people, says the company.

The device creates a report for subsequent analysis. In other words, the results of individual patient blood pressure levels are usable as reference by medical staff.

The device was highlighted by Professor Kario Kazuomi in a paper for the International Society of Hypertension ( ‘Continuous cuffless blood pressure monitoring using photoplethysmography-based PPG2BP-net for high intrasubject blood pressure variations’).

Sky Labs

Sky Labs is a healthcare startup based in Seoul, South Korea. It dates from 2015.

It originally developed CART (Cardio Tracker), another ring-shaped medical device but one for monitoring heart signals for signs of diesease.
