Gas Mixing and Dive Planning Spreadsheets and Charts

The following spreadsheets I created for my own personal use. I created them with data that I thought was useful and a format I understood. I added a couple of links to useful sites (Advanced Diver Magazine Charts) that I don't take credit for. Use the following tools at your own discretion. Both diving and gas mixing are extremely dangerous activities and should not be conducted by any untrained person. These pages do not provide training for either diving or gas mixing. WARNING! I'm not trimix certified. The trimix charts were done for shear recreation and to obtain a thorough understanding in a subject that I was interested in. They will probably do me more good than you. Do the math on your own and the understanding will payoff in the long run.

Diveplanning Spreadsheet Use for planning consumption requirements and CNS%.		Mismatch Gas Matching Spreadsheet Use for teams of mismatched tank volumes and SAC rates.
Nitrox Mixing Spreadsheet Use for mixing empty tanks or topping off nitrox mixes using 100% O2 or banked mix.		Trimix Mixing Spreadsheet Calculates ideal filling PSI and is useful for calculating best mixes. Does not take into account compressibility or heat factors. Blenders must make there own adjustments (fudge factors).WARNING! I'm not Trimix certified.
Nitrox Fill Pressure Chart A reference chart for mixing nitrox to desired fill pressures. I added the colors after I saw the Advanced Diver charts.		< Trimix END 100fsw Fill Pressure Chart This is my quick reference for mixing trimix with an END of 100fsw and a PO2 of 1.4. Both O2 and N2 are considered narcotic in this chart. WARNING! I'm not Trimix certified.
