Decompression illness includes decompression sickness and arterial gas embolism. The CDC notes that either condition can cause serious injury. Distinguishing them in the field may be impossible. Ask about the medical event broadly, rather than searching only for “the bends”. Check whether recompression, hyperbaric oxygen, ambulance transport and specialist consultation are listed or excluded.
Read does scuba insurance cover decompression sickness before comparing a dive-specific policy with ordinary travel cover. A separate dive benefit may focus on hyperbaric treatment and dive injury. Travel protection may focus on the wider journey. Neither description replaces the issued wording, territory, limits or assistance conditions.
Emergency action comes before a claim form. The CDC advises an up-to-date emergency plan, reliable communication and access to medical care. DAN’s emergency guidance says to call local emergency services first after a dive accident. Contact its emergency service afterwards where appropriate. Follow local clinical direction. Provide oxygen only within your training. Do not delay evacuation to collect documents.
After the diver is safe, record the dive history while details are fresh. Note depths, times, gases, ascent concerns, surface intervals, symptom onset, first aid and transport. A careful record supports the clinician and gives the insurer a coherent account. It does not diagnose DCI or decide whether a claim will be accepted.
