New oxygen system a 'game changer' for battlefield

A new portable oxygen delivery system has been developed to improve casualty survival rates for soldiers and civilians.

The system, which was developed by the Wiltshire-based Defence Science and Technology Laboratory (DSTL) and the Defence Medical Service (DMS), weighs just 5kg (11lb) and is able to offer sustained oxygen supply in a safer and easier form than conventional gas cylinders.

"The ability to deliver oxygen at the point of injury represents a game-changing advance in battlefield medicine," said Major Andrew Maggs, DSTL military advisor.

The system works by taking air from the environment and removing nitrogen to leave a breathable oxygen-rich gas that can be delivered to patients.

Oxygen therapy is critical for trauma patients suffering from blood loss, head injuries and lung trauma.

By getting oxygen delivery directly to the point of injury, the system can dramatically improve the likelihood of survival and recovery.

"By reducing logistical burden and improving safety, the system will provide critical care in situations where every second counts," Major Maggs explained.

Dr Paul Hollinshead, DSTL chief executive, added: "In operational terms, this system will reduce the logistical strain on supply chains while improving battlefield care.

"The ability to also reuse the system with external power or replaceable batteries means it offers unparalleled flexibility."

It is not yet known when the system will be first used, but 15 prototypes will soon be ready to deploy.

DSTL is also working on a mass-producible version that can withstand rigorous military use.

The system currently costs £15,000 per unit but it is hoped a more cost effective version can be designed.
