Caltech Develops First Noninvasive Method to Continually Measure Blood Pressure
Device uses sound waves to gather blood pressure data from blood vessels, monitoring the response with ultrasound.
Solving a decades-old problem, a multidisciplinary team of Caltech researchers has figured out a method to noninvasively and continually measure blood pressure anywhere on the body with next to no disruption to the patient. In a small clinical study, the device, which gives patients a gentle buzzing sensation on the skin, produced results akin to those obtained using the standard-of-care blood pressure cuff. The current prototype, built and tested by a spin-off company called Esperto Medical, is housed in a transducer case smaller than a deck of cards and is mounted on an armband, though the researchers say it could eventually fit within a package the size of a watch or adhesive patch.
