Technology Shows Promise for Continuous Monitoring
Researchers at Johns Hopkins University have developed a wearable sensor system combined with artificial intelligence (AI) that can monitor blood pressure continuously without an arterial catheter. Early testing showed that the system could generate blood pressure readings nearly as accurately as invasive arterial lines used in intensive care units and operating rooms.
AI Interprets Signals from Wearable Sensors
The system uses two wearable sensors to capture physiological signals, while AI analyses the data to produce continuous blood pressure waveforms. Researchers initially tested the technology in 28 intensive care patients, with results closely matching readings from arterial catheters.
As per News-Medical, the technology could eventually provide an alternative to arterial lines, which carry risks such as bleeding, clotting and infection.
Potential Beyond the ICU
The researchers believe the technology could expand continuous blood pressure monitoring beyond critical-care settings. It may eventually support remote monitoring for people with hypertension and enable more convenient, continuous cardiovascular health tracking.
However, the system remains investigational, and larger studies and further clinical validation are needed before it can replace invasive blood pressure monitoring.
