Bed sensors to monitor cardiac activity (Courtesy of U. Missouri)
Researchers at the University of Missouri have been testing the benefits of non-invasive, contact-free bed sensors for the health of elderly people living in a retirement community.
The sensors continuously monitor heart rate, respiration rate and overall cardiac activity. A hydraulic transducer, a flexible tube of water, measures the mechanical effects of blood flow in the circulatory system. In the study, four hydraulic transducers were placed under a mattress to capture participants’ cardiac data.
According to the researchers, continuous heart rate monitoring provides a significant benefit for older adults. It also identifies sleep patterns, whose variations can constitute an early sign of illness.
