Comprehensive technical diving tool suite for gas mixing, dive planning, and safety analysis. Professional-grade calculations with real-time safety warnings and conservative rounding algorithms.
Optimal nitrox and trimix gas mixture recommendations based on target depth. Calculates best oxygen and helium percentages with MOD verification, END analysis, and gas density safety checks. Supports recreational nitrox from 21-40% oxygen and technical trimix with customizable helium fractions.
Real-time gas mixing calculations with live feedback. Adjust oxygen and helium percentages to see instant MOD, END, and gas density results. Visual safety warnings for ppO2 limits, narcotic depth, and breathing gas density. Supports both open circuit and closed circuit rebreather configurations.
Cylinder blending calculations for partial pressure fills and continuous mixing. Determine exact fill pressures needed for target gas mixtures. Includes top-off calculations, mixing validation, and safety margin analysis for professional gas blending operations.
Maximum Operating Depth calculations with configurable ppO2 limits. Verify safe diving depths for any gas mixture with working limits (1.2-1.4 ATA) and emergency limits (1.6 ATA). Essential safety tool for technical dive planning and gas switching procedures.
Surface Air Consumption and Respiratory Minute Volume calculations for dive planning. Input dive profile data to determine personal air consumption rates. Critical for gas management, emergency planning, and determining adequate air supply for technical diving operations.
Calculate available bottom time based on gas supply, consumption rates, and safety margins. Factors in ascent time, safety stops, and emergency reserves. Essential for technical diving operations requiring precise gas management and dive duration planning.
For 30-meter dives, optimal nitrox mixtures range from 28-32% oxygen. MOD calculations ensure safe ppO2 limits: EANx28 has MOD of 40m, EANx30 has MOD of 37m, EANx32 has MOD of 34m at 1.4 ATA working limit.
Deep dives beyond 40 meters require trimix to reduce nitrogen narcosis. Standard mixes include 18/45 for 60m, 15/55 for 70m, and 12/65 for 80m+. Helium percentage calculated to keep END below 30 meters for optimal safety.
Breathing gas density must remain below 6.2 g/L for safe work of breathing. DiveBlendr calculates gas density at depth using partial pressure corrections and warns when density exceeds recommended limits for technical diving safety.
ppO2 calculations critical for technical diving safety. Working limits: 1.2 ATA for bottom phases, 1.4 ATA for ascent, 1.6 ATA for decompression stops. CCR divers use lower 1.3 ATA limit for setpoint management.
