What should be done if a diver experiences decompression sickness in the water?

When a diver experiences decompression sickness (DCS) in the water, the best course of action is to dispatch a standby diver and continue decompression. This response is crucial because rapid ascent can worsen the diver's condition and exacerbate the symptoms of DCS. Continuing the decompression protocol ensures that the diver can safely ascend at the correct rate, allowing for gas exchange and reducing the potential risks associated with the condition.

Handling the situation this way maintains safety and minimizes the risk of injury to the affected diver. Dispatching a standby diver allows for real-time monitoring and assistance, ensuring that the affected diver can receive support while minimizing further complications during the decompression phase. It is important to follow established protocols in such emergencies to prioritize the diver's wellbeing effectively.
