The Army volume-cycled respirator is designed to assist or control the ventilation of patients it must necessarily operate in military environments. Medical evaluation of the Model 1 prototype of this respirator demonstrated insufficiencies in the assist mode of operation and a need to expand the functional capabilities. This report describes the engineering tests performed on the Model 2 prototype of the respirator which is powered and controlled by two bistable fluid amplifiers the Model 1 version used only one amplifier. The newer model can also be pressure-cycled. The tests performed indicate that the Model 2 prototype satisfies the expanded set of requirements established for it with two exceptions. The exceptions pertain to the requirements for inspiratory times and minute volumes. Medical evaluation is now underway to determine the respirators acceptability as a clinical tool.
