What should a diver do immediately after surfacing if they suspect DCS?

The appropriate action for a diver who suspects decompression sickness (DCS) after surfacing is to seek medical help. DCS can result from nitrogen bubbles forming in the body due to rapid ascents or extended bottom times without proper decompression stops. Symptoms may include joint pain, dizziness, fatigue, and shortness of breath, among others.

Prompt medical attention is critical because DCS can lead to serious complications if not addressed quickly. Treatment usually involves hyperbaric oxygen therapy, which can significantly improve outcomes for those afflicted. Immediate self-assessment or continuation of diving could worsen the condition or lead to further complications, while rest and hydration, although important for overall recovery, do not address the urgent nature of DCS treatment. Seeking professional medical assistance allows divers to receive the appropriate care tailored to their conditions promptly.
