A versatile closed circuit.

A versatile closed circuit with new features is described. It may be used in a totally closed manner, without continuous gas inflow. As gas is absorbed from the circuit, it is replaced through a demand valve. Facilities for continuous gas input and use of a ventilator are included, and one control converts it to a non-rebreathing circuit. The circuit has excellent mechanical characteristics in ...
