Aktiia SA’s wrist-worn, continuous blood pressure monitor, which has been in use in the EU since 2021, could soon be coming to the U.S. The Aktiia bracelet uses photoplethysmography, the technology perhaps best known for providing blood oxygenation readings via pulse oximeters, and an algorithm based on thousands of readings to estimate blood pressure as wearers go about their daily activities.

Biobeat Technologies Ltd. expanded its U.S. FDA-cleared remote patient monitoring offerings with a double nod from the agency for its sensors to monitor stroke volume and cardiac output. The two new indications join its capabilities for measuring the five vital signs assessed in any medical visit—blood pressure, blood oxygen saturation, pulse rate, respiratory rate and body temperature—all of which can be done using photoplethysmography (PPG) on sensors embedded on either a short-term chest patch or a more durable wrist monitor.

Biobeat Technologies Ltd. reported its remote patient monitoring system received FDA clearance to monitor respiratory rate and body temperature. The wireless chest and wrist monitoring device is already cleared for cuffless blood pressure monitoring, blood oxygen saturation and pulse rate. The artificial intelligence platform utilizes a photoplethysmography-based sensor at the surface of the skin that measures volumetric variations of blood circulation.
