Wireless point-of-care ultrasound in a multiplace hyperbaric chamber

Area of Science:

• Medical Technology
• Hyperbaric Medicine
• Point-of-Care Ultrasound

Background:

• Electronic devices are restricted in hyperbaric oxygen (HBO2) chambers due to fire risk.
• Point-of-care ultrasound (POCUS) is widely used but limited in hyperbaric environments.
• This study assesses a wireless POCUS device for hyperbaric use.

Purpose of the Study:

• To evaluate the proof of concept, safety, and performance of a wireless, off-the-shelf handheld POCUS device within a hyperbaric environment.
• To determine if the GE Vscan Air can be utilized in hyperbaric chambers.
• To assess the device's functionality and safety under pressure and high oxygen concentrations.

Main Methods:

• Tested GE Vscan Air in a Class C chamber (100% nitrogen up to 4.0 ATA).
• Evaluated the device paired with an encased iPad in a Class A chamber (21% oxygen) at 2.4 ATA and 2.8 ATA.
• Monitored device temperature, image quality, functionality, and wireless connectivity.

Main Results:

• A minor modification (puncturing the power button) was needed for the GE Vscan Air to function continuously.
• The device operated without degradation in function or image quality.
• No overheating or fire hazards were observed, and wireless connectivity was maintained.

Conclusions:

• The GE Vscan Air, with a minor modification, is suitable for use in multi-place hyperbaric chambers.
• Wireless capabilities enable seamless integration with external devices for monitoring.
• This validates the use of standard wireless POCUS devices in hyperbaric settings.
