Advanced decompression dive planning including:
  • Gas planning based on equivalent narcotic depths, nitrogen and helium absorption and elimination, CNS and OUT limits, Isobaric Counter diffusion, volume requirements, etc.
  • Decompression gas choices
  • Tables vs. personal dive computers
  • Emergency and contingency planning (equipment failure, omitted decompression, etc)
Decompression diving procedures
  • Equipment selection
  • Pre-dive checks and drills
  • Stress analysis and mitigation
