CCR MIXED GAS DIVER Plan And Make Dives Using Trimix/heliox As A Diluent Using Ccr

The CCR MIXED GAS DIVER with REMOTE AREA DIVE

As a CCR Air Diluent Decompression or Helitrox Diluent Decompression Diver, the Mixed Gas CCR Diver course is your next step into closed circuit rebreather diving, it is your opportunity to explore a little deeper. Using the latest in technology CCR’s maximize your gas supply and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen (PPO2). During the dives your Instructor will teach you all the necessary skills to conduct CCR dives utilizing helium as a diluent gas and oxygen levels as low as 16 percent to a maximum depth of 60 metres/200 feet.

Who this course is for:

The certified Air Diluent Decompression or Helitrox Diluent Decompression Diver (or equivalent) looking to extend their depth limitations.

Course prerequisites:

  • Minimum age 18
  • Provide a verified log of a minimum of 50 rebreather hours distributed over a minimum of 50 dives on the specific rebreather. If the diver has 50 hours on another CCR, only 25 hours are required to be on the specific unit
  • Have completed and qualified the Air Diluent Decompression Procedures Rebreather/CCR Helitrox Diluent Decompression Procedures Diver course or equivalent

What you can expect to learn:

The Diving Rebreathers Student Manual is required for use as a review/recap document. The instructor may use any additional text or materials they feel will represent the topic in an educational manner. The following topics must be covered during the course:

  • Gas physiology
    • Oxygen (O2) toxicity
    • Hypoxia
    • Nitrogen absorption
    • Helium absorption
    • HPNS
    • Carbon dioxide (CO2) toxicity
    • Gas consumption
    • Gas mixing
  • Formula Work
    • Oxygen (O2) metabolizing calculations
    • Manually controlled closed circuit rebreathers
    • Equivalent narcosis depth theory
    • Central nervous system (CNS) tracking
    • Oxygen tracking units (OTU)
    • Gas management
  • Dive tables
    • Creation of custom dive tables appropriate to dive depths
    • Creation of lower percentage of oxygen (PO2) diluent to support loop flushing and bailout at depth
  • Dive computers
    • Mix adjustable
    • Constant partial pressure of oxygen (PPO2)
    • Oxygen (O2) integrated
  • Dive planning
    • Operational planning
  • Equipment maintenance
    • Fuel cell management
    • Loop configurations
    • Additional fitted equipment and modifications

Day #1 - Introduction, Theory, Equipment assembly & critique
Day #2 - Dive 1, Dive 2
Day #3 - Dive 3, Dive 4
Day #4 - Dive 5, Dive 6, Theory Exam
