This course introduces the use of Helitrox in CCR systems, extending dives to greater depths while minimizing nitrogen narcosis and gas density issues.

Divers gain expertise in Helitrox (helium-nitrogen-oxygen mixtures) dive planning, gas switching, and PO₂ management. Theoretical study combines with practical diving exercises to ensure safe handling of helium-based breathing gases and mastery of decompression protocols for deeper dives.

What you'll learn:

• Helitrox composition, properties, and benefits for CCR.
• Planning and conducting deep Helitrox dives with controlled decompression.
• Gas switches and monitoring oxygen partial pressures.
• Complex emergency scenarios and safe ascents.
• Maintenance and calibration for helium-based operations.
