Embodiments include an inflatable blast-induced brain injury prevention device for living beings such as soldiers. The device may include one or more inflatable chambers that cooperate to form a substantially toroidal cervical collar configured to surround the soldier's neck. An inflator unit, activated by an initiator may be coupled to the one or more inflatable chambers to inflate the one or more inflatable chambers. An electronic control unit (ECU) in electrical communication with the initiator and in electrical communication with at least one sensor may be configured to measure atmospheric air pressure. The ECU may be programmed to activate the initiator when the air pressure measured by the sensor exceeds a threshold air pressure.
