Modular Multi-person Medical Oxygen Delivery System

Paragon will mature the design of a Modular Multi-person Medical Oxygen Delivery System (M3ODS). M3ODS provides electronically monitored and controlled hyperbaric oxygen to up to 35 rescued but nitrogen saturated submariners. M3ODS can be readily integrated into existing rescue chambers, vessels and closed-circuit oxygen rebreathers such as the MBS 2000. M3ODS can also be implemented in other emerging multi-person rebreathers that may offer advantages over the single-person MBS 2000. Our primary innovation is a modern and automated inspired O2 partial pressure (PPO2) architecture that includes the controller, sensors, and other components required for operation. M3ODS electronically controls PPO2 to each submariner at a user-specified PPO2 setpoint and at up to 2.8 ATA (41 psi) at a depth of 60 FSW and up to the pressure depth below 60 FSW. The controller maintains PPO2 at the setpoint throughout changes in temperature and humidity and it will not allow the PPO2 to rise above 2.8 ATA to precluded CNS oxygen toxicity concerns. A local PPO2 setpoint adjustment is provided and the PPO2 setpoint and inspired PPO2 are displayed locally. A unique identifier along with PPO2 setpoint and inspired O2 for each sailor will be transmitted via wire to allow for remote monitoring.
