Research pick: Wear and care - "Wearable sensors in critical care medicine"

Wearable technology is well known to anyone with a fitness tracker but it is also moving into critical care medicine. Research in the International Journal of Systems, Control and Communications has looked at how wearables might change the management of patients in intensive care units (ICUs). Such devices can provide continuous, real-time data for healthcare professionals following the vital signs and movements of critically ill patients. The technology might offer a more personalized and less invasive approach to treatment.

Decheng Fan of the University of Shanghai for Science and Technology, Junmin Li and Jingjing Fang of The Second Military Medical University, Jianbo Su of Shanghai Jiao Tong University, Shanghai, China, explain that conventional ICU monitoring usually relies on bulky equipment such as heart monitors, devices for monitoring respiratory function, and measuring blood pressure, for instance. These methods, while effective, usually require active and regular intervention from the healthcare workers. There is also usually a need for taking samples of blood and urine etc, which is usually invasive and carries a risk of introducing infection.

Wearable technology could offer a viable alternative to the more intrusive and invasive technologies that have been used for many years. One of the biggest benefits is the non-invasive and continuous monitoring that wearables could offer. Wearables will support healthcare by transmitting personalized data to clinicians, allowing them to make decisions in real time to assist patients with complex, life-threatening conditions such as multi-organ failure.

Researchers are already working on multifunctional sensors that could be integrated into a single device to streamline the whole process of data assimilation and transmission. Such devices could be of great benefit in specialist care settings where resources are scarce, such as during a pandemic, for instance.
