    Default SCR Gas Calculation

    Has anyone found an online or computer based calculation program to calculating your breathing mixture on an SCR.

    I know the formula but it's difficult to teach sometimes.

    Calculating is very dangerous. Individual SAC rates, exact flow, and the workload are all variables that can alter the calculation at any time. It is definitely better to have a system to monitor the actual mixture in the loop.

    yes yes... however... i used to know a website that would take your sac rate and figure out your breathing mix (bag mix) for your NDL

    There are circumstances in which the cylinder flows and mixtures may present a situation of hypoxia for the diver. The worst situation is using a lean cylinder by a plane at low speed. In the example given in Section 6.3, if the Ducks were VO 2 to 1.9, so the loop is fO2 0.20. Even in a VO2 of 1.35 would fO2 of 0.30, which would be 30% that diving was planned.
