Abstract:

An underwater breathing apparatus capable of supplying either 100% air, 100% oxygen, or an air/oxygen mixture to a diver as needed. A selector switch clearly indicates what is being supplied through the separate secondary breathing apparatus (or "octopus") of the rescuing diver. Also disclosed is a face mask to be placed around the nose and mouth of a diver in distress that is configured with an adaptor which accepts and seals around the mouthpiece of the secondary breathing apparatus. In this fashion, the rescuing diver can supply either air, oxygen, or a mixture of the two to a diver in distress in either a free-flow state or upon demand.
