What should a diver do if they miss a required decompression stop while using the RDP?

When a diver misses a required decompression stop while using the Recreational Dive Planner (RDP), it is crucial to prioritize safety to minimize the risk of decompression sickness (DCS). The correct action in this situation is to remain on the surface, rest, and monitor for any signs of DCS. This includes symptoms like joint pain, dizziness, or difficulty breathing.

Breathing 100% oxygen can be an effective way to treat or mitigate the symptoms of DCS, as it helps reduce nitrogen bubbles in the body more quickly than regular air. Additionally, it is advised to avoid diving for at least 24 hours after such an incident to allow the body to eliminate excess nitrogen and to recover fully before resuming any diving activities. This protocol is important to prevent further complications and ensure the diver’s health and safety.

Taking immediate action to surface quickly or continuing to dive can exacerbate the situation and increase the risk of serious harm. Hence, the recommended course of action emphasizes monitoring and resting while taking precautionary measures to observe for any potential side effects of missing the decompression stop.
