Post-dive care after suspected DCS typically includes which of the following?

• A. Observation, hydration, rest, and medical evaluation; follow-up with HBOT as advised.
• B. Immediate physical exertion and dehydration to flush nitrogen from the system.
• C. Complete bed rest for 48 hours without medical follow-up.
• D. Self-treatment with over-the-counter analgesics and return to work.

Answer: (A)

Post-dive care after suspected decompression illness centers on watching for symptom changes, staying hydrated, resting, and getting a medical assessment promptly. DCS symptoms can start slowly or progress after surfacing, so observation helps catch any worsening early and guides treatment decisions. Hydration supports circulation and helps with gas elimination, while rest reduces physical stress that could drive bubbles to migrate or cause more injury. A medical evaluation is essential to confirm whether DCS is present and to determine if hyperbaric oxygen therapy is needed, since HBOT is the main treatment that accelerates bubble resolution and improves tissue oxygen delivery. Follow-up HBOT sessions may be advised based on the assessment. The other approaches aren’t appropriate because they either delay necessary medical evaluation and treatment, or involve activity or self-care that can worsen or miss evolving DCS symptoms.
