Emergency Procedures

Some areas to review are:

Predisposition to Decompression Illness (DCI)

  • Fitness to dive
  • Alcohol and / or lack of sleep
  • Multiple ascents
  • Multiple days diving
  • 4 deep dives
  • Diving at altitude
  • Exertion during diving
  • Cold water
  • High CO2 levels
  • Exercise after diving
  • Hot showers after diving
  • Flying or driving to altitude after diving


Avoiding DCI

  • Appropriate training
  • Avoid the previous list if you can
  • Plan your diving day
  • Revise computer use / backup tables


Planning a dive

  • Depth
  • Duration
  • Surface intervals
  • Decompression requirements and appropriate safety margins
  • Current and state of tide
  • Exit point

 

First Aid for DCI

  • ABC - Airway; Breathing; Circulation
  • Patient a. flat on back (conscious) 
               b. Recovery position (unconscious).
  • High flow oxygen 15 Lpm  (Hudson mask does not provide 100%.)
  • Call for assistance (DES) 0800 4 DES 111 or 09 445 8454, these are toll free. The Diver Emergency Service will advise you as to where and how to seek medical assistance.

    i.e., log book, dive recorder or computer. Include all diving within the previous seven days.
  • Medical history and current medications
  • Remember to secure any equipment used to aid in investigating the cause of the problem.

Evacuation 

  • There are few dive areas in the South Island from which road evacuation can be accomplished below 300 m.
  • Road transport is adequate if quicker or nearly as quick as air transport.
  • Keep patient below 300 m altitude or cabin pressure.
  • Direct transfer from dive site to Christchurch Hospital is preferable if patient stable.
  • Helicopter has limited range so will often transfer patient to fixed-wing via base hospital.
  • For referrers, see Patient Referral and Transfer Procedures on CDHB Intranet, HealthPathways, Blue Book and provided to all Emergency Departments in our region.
