Pulseless diver treatment sequence?

• A. ABC's; Immediately start CPR; Place AED on diver and 100% O2; Bring patient to hospital
• B. Check for pulse, then call for transport
• C. Only provide rescue breaths and do not start CPR
• D. Wait for a wave to subside and then resuscitate

Answer: (D)

When a diver is pulseless, the priority is immediate life support to restore circulation and oxygen delivery. The best approach is to begin high-quality CPR right away and use an AED as soon as it’s available, without delay. Start chest compressions promptly (and provide ventilations as trained) so that blood flow to the brain and heart is maintained while you organize definitive care. If a shockable rhythm is identified, deliver a defibrillation as soon as possible, then resume CPR immediately. Administer 100% oxygen if equipment is on hand, and arrange rapid transport to an advanced care facility for ongoing management. Delaying resuscitation to wait for environmental factors to improve wastes crucial minutes and lowers survival chances, so actions should proceed on the spot rather than waiting for waves or other conditions to subside.
