Wireless transmission of biosignals for hyperbaric chamber applications

Area of Science:

• Biomedical Engineering
• Medical Devices
• Wireless Communication

Background:

• Hyperbaric chambers, increasingly used for novel oxygen therapies, pose challenges for patient monitoring due to metallic walls isolating patients.
• Transmitting vital signs from within a hyperbaric chamber traditionally requires cumbersome wiring, complicating patient care and data acquisition.

Purpose of the Study:

• To develop and validate a wireless system for transmitting biosignals from inside a hyperbaric chamber to an external monitoring location.
• To overcome the limitations of wired connections through metallic chamber walls.
• To create a versatile platform adaptable for various biosignal monitoring needs.

Main Methods:

• Design and implementation of a wearable, battery-powered device.
• Utilization of a ZigBee-based wireless network for data transmission.
• Testing of the system for transmitting electrocardiography (ECG) signals.

Main Results:

• Successful wireless transmission of biosignals, specifically ECG, from within a hyperbaric chamber.
• Demonstration of a practical solution to bypass the physical isolation imposed by chamber walls.
• The developed device proved effective and adaptable for biosignal monitoring.

Conclusions:

• The proposed wireless system effectively transmits biosignals from hyperbaric chambers, enhancing patient monitoring capabilities.
• The wearable device offers a viable alternative to traditional wired methods, improving safety and convenience.
• The system's design allows for future adaptation to monitor other critical patient biosignals.
