Claim:
1. A dive resource management system for a rebreather breathing loop comprising: a gas supply, wherein the gas supply is a single gas mix; a gas supply pressure regulator; a scrubber canister; a counterlung; a first sensor adapted to measure ambient pressure; a pressure transducer adapted to indicate depth as a function of ambient pressure; a second sensor adapted to measure partial pressure of oxygen; a first valve adapted to add the gas supply to the rebreather breathing loop; a power source; a clock; connecting hoses; check valves adapted to control the direction of flow of gas in the rebreather breathing; and a processor adapted to wherein the processor is further adapted to send a signal to adjust a setpoint for partial pressure of oxygen in the rebreather breathing loop, wherein the setpoint is automatically and continuously calculated and adjusted throughout a dive using diver selected values for a control parameter, a reduction coefficient, and a partial pressure of oxygen, wherein the partial pressure of oxygen is based on a concentration of oxygen in the gas supply and ambient pressure; and wherein the gas supply is a single high-pressure source containing an oxygen-enriched gas mixture where the concentration of oxygen is less than 100%.
