Abstract : The evaluation was made to determine the suitability of the Northill Air Lung for Naval service. The apparatus was evaluated objectively by breathing machine tests and depth swimming test, with respiratory pressure instrumentation. It was evaluated subjectively by swimming pool runs. Breathing machine test results are summarized as graphs of peak inspiratory pressure against cylinder pressure. Depth swimming test results are summarized as graphs of peak respiratory pressures, cylinder pressure, respiratory minute volume and respiratory rate, all against time. Subjective comments for swimming pool runs are given verbatim. The results are discussed constructively and lead to specific conclusions about the apparatus and its suitability for Naval service.
