What should be done if pain is relieved at a depth greater than 66 feet?

When pain is relieved at a depth greater than 66 feet, the appropriate action is to use Treatment Table 2A. This table is specifically designed for cases involving decompression sickness and is applied when symptoms persist or change at depths below 66 feet. The rationale behind using Treatment Table 2A in this scenario is that it provides a regimen for managing significant symptoms associated with dive-related injuries, where the relief at depth indicates the need for a controlled and structured response to ensure the diver's safety and health.

During treatment, the diver may need to ascend gradually and may require additional oxygen therapy as part of the protocol outlined in Treatment Table 2A. Such careful management helps to prevent further complications and aids in the recovery process following decompression sickness. Understanding the correlation between symptoms and the appropriate treatment table is critical for dive personnel to provide effective care under these circumstances.
