What is required for proper decompression diving?

Minimal training and standard scuba gear
Specialized training and additional equipment
Only basic first-aid knowledge
Standard equipment and no support

The correct answer is: Specialized training and additional equipment

Proper decompression diving involves complex physiological principles and the management of specific risks associated with extended depths and times underwater. Specialized training is essential to understand the effects of nitrogen and other inert gases under pressure, as well as to know how to use dive tables or dive computers for safe ascent profiles. This training allows divers to implement proper decompression stops to off-gas excess nitrogen absorbed during the dive, significantly reducing the risk of decompression sickness (the bends). In addition to specialized training, divers engaged in decompression diving typically require additional equipment, such as a dive computer capable of tracking nitrogen saturation and suggesting safe ascent profiles, as well as possibly redundant air supplies. Specific gas mixtures may also be used to optimize inert gas absorption and reduce the risks associated with deeper dives. This comprehensive approach ensures that divers are equipped with both the knowledge and tools necessary for conducting safe and effective decompression dives.
