Abstract: Systems and methods for use in multimedia training are disclosed. The system includes a server having data files adapted be accessed by one or more terminals, and a terminal adapted to communicate with the server. The terminal has a processor adapted to control execution of a training program. The execution includes accessing at least one of the data files on the server.

Abstract: A hyperbaric oxygen therapy system includes a pressure vessel containing a gas, an oxygen concentration measurement apparatus for monitoring the concentration of oxygen in the gas, an environmental control apparatus for controlling the temperature of the gas in the vessel, and a pressure/ventilation control apparatus for controlling the pressure of the gas in the vessel. The pressure vessel is capable of accommodating a patient. The oxygen concentration measurement apparatus includes an oxygen concentration analyzer and a plurality of gas lines connecting the oxygen analyzer to the pressure vessel. The pressure/ventilation control apparatus includes a pressure controlling valve, a pressure sensor, a ventilation valve, and a controller having a programmable pressure profile. The environmental control apparatus includes a scrubber, a heat exchanger and a blower located within the pressure vessel. A compressor for the system includes a compressor silencer.

Abstract: A latching mechanism for a pressure chamber for hypobaric use is disclosed. The mechanism includes one or more pin modules positioned on a periphery of a door of the pressure chamber, the door being adapted to open into the chamber and abut a frame of the pressure chamber when the door is in a closed position. The mechanism further includes an actuator for selectively engaging or disengaging the pin with the frame. The pin module may include a pin adapted to be selectively positioned in an engaged or a disengaged position. The pin in the engaged position extends from the door to the frame of the pressure chamber, thereby preventing the door from opening into the chamber. The pin module includes a cylinder for actuating the pin. The cylinder may be a pneumatic cylinder operated with pneumatic pressure. The pneumatic cylinder of each of the pin modules may be centrally actuated.
