What is the process for referring a diver for hyperbaric treatment after suspected DCS?

• A. Wait and see.
• B. Immediate medical evaluation, HBOT referral per protocol, and transport to HBOT facility as indicated.
• C. Self-administered treatments.
• D. Notify only after returning to shore.

Answer: (B)

Suspected decompression sickness is a time-critical medical emergency. The correct approach is immediate medical evaluation, refer to hyperbaric oxygen therapy per the dive protocol, and arrange transport to an approved hyperbaric facility as indicated. This ensures rapid assessment and the definitive treatment—recompression with high‑flow oxygen—that can minimize bubble-related injury and improve outcomes. Waiting to see what happens, attempting self-treatment, or delaying referral until after returning to shore can allow symptoms to worsen and increase the risk of permanent harm, so referral and transport should be handled promptly by medical professionals following established protocols.
