Blood Pressure Camera

2022: Camera Announcement

On December 5, 2022, the University of South Australia (UniSA) announced the development of an innovative system to measure a patient's blood pressure using a camera.

Iraqi researchers from the Technical University of Baghdad participated in the creation of the complex. Proposed technology provides for contactless determination of systolic and diastolic pressure. Scientists claim that their method could replace the existing method of attaching an inflatable cuff to a person's hand or wrist.

A video camera has been developed that determines blood pressure

The solution provides for shooting a patient from a short distance for 10 seconds and extracting cardiac signals from two areas of the forehead using artificial intelligence algorithms. Testing of the system was carried out on 25 volunteers with different skin tones and in changing lighting conditions. It was found that the accuracy of measuring systolic and diastolic pressure by about 90% corresponds to the readings obtained using a digital sphygmomanometer - tonometer for non-invasive blood pressure measurement.

Blood pressure monitoring is needed to identify and treat cardiovascular disease, the leading cause of global mortality, from which almost 18 million people died in 2019. The health sector needs a system that can accurately measure blood pressure and assess cardiovascular risks when physical contact with patients is unsafe or difficult, for example, during a recent outbreak, the coronavirus researchers say.

Advanced technology is the result of work as part of a long-term project: back in 2017, UniSA and an Iraqi research team demonstrated image processing algorithms that can extract a person's heart rate from drone footage.^[1]
