A new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin could help people detect cardiovascular problems earlier on and with greater precision. Applications include real-time, continuous monitoring of blood pressure changes in patients with heart or lung disease, as well as patients who are critically ill or undergoing surgery. The patch uses ultrasound, so it could potentially be used to non-invasively track other vital signs and physiological signals from places deep inside the body.
The new ultrasound patch can continuously monitor central blood pressure in major arteries as deep as four centimetres (more than one inch) below the skin. Physicians involved with the study say the technology would be useful in various inpatient procedures. The device measures central blood pressure—which differs from the blood pressure that’s…
