Compact, Logistics Free Electrochemical Reduced Oxygen Breathing Device

All military and many commercial aviators are required to undergo periodic hypoxia training to recognize the onset of hypoxic conditions and practice recovery skills. Current training is performed with the Reduced Oxygen Breathing Device 2 (ROBD2) which mixes oxygen and nitrogen to produce reduced oxygen concentration air mixtures representative of hypoxic conditions. However, the ROBD2 requires bulky compressed gas cylinders which decrease the mobility of the device and increase usage logistics. Additionally, the device delivers a continuous flow, increasing the risk of air starvation. Lynntech proposes the use of an electrochemical oxygen separator to directly reduce the oxygen concentration of the air delivered to the hypoxia trainee. The device accurately removes a variable amount of oxygen from the air stream to produce the required oxygen concentrations, simulating hypoxic conditions from sea level to beyond 30,000 feet. The device will deliver pressure-on-demand flow to a flight mask to avoid air starvation, accurately simulating flight systems. A pulse oximeter, flow meter and oxygen sensor will be integrated into the unit to provide biometric monitoring. The mobile system will weigh less than 25 lbs and operate on 110 VAC. The only consumables will be electrical energy, atmospheric air and liquid water.
