New device to accurately measure blood pressure

Researchers at University of Leicester, UK, have developed a new device which can accurately measure blood pressure.

Unlike the traditional method, the new device measures blood pressure near the heart, specifically in the aorta, also known as central aortic systolic pressure (CASP).

The new approach is based on the device developed by Singapore-based HealthSTATS International, which can measure the pulse rate as well as the actual pulse wave.

To develop the new approach, researchers developed an algorithm which can accurately calculate CASP through pulse wave measurements.

In a study, the CASP measurements using new approach were found to be 99% accurate when compared to those measured by an invasive, surgical CASP method.

The new device looks like a wrist watch and is to be worn for 24 hours to provide an accurate blood pressure measurement.
