EFR Guidelines Changes, Part I: AB-CABS
Recent PADI Training Bulletins and EFR The Responder newsletters announced that greater emphasis on early and effective chest compressions was the main aim of the 2010 ILCOR (International Liaison Council on Resuscitation) Guidelines. You’ll notice therefore that the traditional ABCs order of priority care in EFR courses has been expanded to the new order of AB-CABS, continuing the steps into the Cycle of Care (rather than the patient’s lifeline).

The AB portion of AB-CABS reminds emergency responders to quickly check if the patient’s Airway is open and if he is Breathing normally. If not, the responder moves straight into delivering Chest Compressions, opening the Airway and then Breathing for the patient (30:2). If he is breathing normally, then the responder can move further in the Cycle of Care, i.e. the S to check for Serious Bleeding, Shock and Spinal Injury.
 
Jellyfish Stings
First aid for jellyfish stings is new to the AHA First Aid Guidelines. First aid for jellyfish stings consists of two important actions: preventing further nematocyst discharge and pain relief.
To inactivate venom load and prevent further envenomation, jellyfish stings should be liberally washed with vinegar (four to six percent acetic acid solution) as soon as possible for at least 30 seconds². If vinegar is not available, a baking soda slurry may be used instead.¹⁹
For the treatment of pain, after the nematocysts are removed or deactivated, jellyfish stings should be treated with hot water immersion when possible. If hot water is not available, dry hot packs or, as a second choice, dry cold packs may be helpful in decreasing pain but these are not as effective as hot water.^20,24,25
 
Snakebites
Do not apply suction as first aid for snakebites². Suction has no clinical benefit²⁶ and it may aggravate the injury.^27-28
Applying a pressure immobilisation bandage with sufficient pressure around the entire length of the bitten extremity is an effective and safe way to slow the dissemination of venom by slowing lymph flow.^29-30 For practical purposes, pressure is sufficient if the bandage is comfortably tight and snug but allows a finger to be slipped under it.² Initially it was theorised that slowing lymphatic flow by external pressure would only benefit victims bitten by snakes producing neurotoxic venom, but the effectiveness of pressure immobilisation has also been demonstrated for bites by non-neurotoxic American snakes.^30-31
