Abstract : The report covers the evaluation of locally modified Aqua-Lung Regulator compared to the standard aqua-lung regulator to determine the suitability of the modified apparatus for Naval service. The regulators were tested objectively by breathing machine runs with instrumentation for respiratory pressure, respiratory minute volume, and breathing rate. Breathing machine runs are summerized as graphs of peak respiratory pressure versus depth and cylinder pressure. The results are discussed constructively and lead to the recommendation that the modification be included in aqua-lung apparatus used in the Naval service. (Modified author abstract)
