A ZigBee-based wireless system for monitoring vital signs in hyperbaric chambers: Technical report

Abstract

[EN] This paper presents a wireless ZigBee-based system to replace the traditional wired communication link of the hyperbaric chambers, which allows reducing the costs of seals capable of withstanding the internal pressures and giving rise to a more versatile system. The system is able to capture and process individual vital signs like the electrocardiography signal, and other four analogue sources, sending the data to an external computer allowing analysis, representation and sharing them with the medical staff. This work solves problems such as the attenuation of the signal produced by the metal walls of the hyperbaric chamber obtaining a coverage area big enough to manage up to six patients with an effective data rate conversion of 2kHz. Furthermore, a battery-based and multi-parameter platform is designed for multi-patient hyperbaric chambers.
