Rubicon Foundation Archive (http://rubicon-foundation.org)Richardson and Shreeves: Overview of PADI Enriched Air Diver Programstay at or above the depth levels upon which you base your oxygen exposure. If you don't tracklevels, you must base your oxygen exposure on the deepest depth and total dive time. If you'reonly making one or two dives, you may find this much simpler anyway.Diving Emergencies and Enriched AirIf a diver convulses underwater (possibly due to oxygen toxicity), the generallyrecommended action is to handle the emergency as you would for an unconscious diverunderwater. (Note: This recommendation is based on the U.S. Navy procedures, which theDivers Alert Network defers to in this situation because there's been little study of this inrecreational diving.)a. Hold the diver's mouthpiece in (if still retained). Do not attempt to replace it if it is out ofthe mouth.b. Immediately bring the diver to the surface and check for breathing.c. Establish ample positive buoyancy for both you and the victim.d. Call for assistance as needed and available and begin in-water rescue breaths if the victimisn't breathing. Take the diver to the boat or shore, and help remove the diver from thewater.e. Once out of the water, check for a pulse and breathing. If they're absent, begin/ continuerescue breaths and/or CPR. In any case, contact emergency medical care. If the diver isbreathing, begin first aid for DCI as a precaution.f. Even if the diver appears fully recovered, the patient should be examined by a physician.Note: Some experts recommend that if a diver's mouthpiece is in place, to hold it in thereand not begin the ascent until the convulsion subsides. After the convulsion ends, bring the diverimmediately to the surface. This recommendation is based on the fact that a convulsing divermay hold his breath. In any case, the primary concern is getting the diver to the surface toprevent drowning, so you can begin first aid and get help.If a diver is suspected of having decompression sickness after an enriched air dive,administer oxygen, first aid, and obtain emergency help exactly as you would if the diver hadbeen diving with air. If possible, inform emergency personnel and the recompression facility ofwhat the diver's time and depth was, that the diver was using enriched air, and what the blendwas. In a DCI emergency, if you run out of emergency oxygen before you can get a breathingpatient into emergency medical care, have the patient breathe any enriched air available. Whilenot as beneficial as 100 percent oxygen, enriched air has more oxygen than air.PADI EANx: Certification Numbers History1.
