Patient vital signs monitoring using Wireless Body Area Networks

Today hospitals are equipped with many electronic transmitting devices, which results in electromagnetic interference that may impair wireless transmissions between medical devices. On the other hand, reliable and continuous collection via wireless communications of patient vital signs such as blood pressure and flow, core temperature, ECG, carbon dioxide (CO₂) concentration is crucial for making real-time triage decisions. Hence, a novel wireless communication solution that seamlessly supports patient mobility and that prioritizes vital signs transmission using Wireless Body Area Networks (WBANs) is developed, implemented in TinyOS, and tested on Shimmer biomedical wireless sensor motes.
