If a diver complains of elbow pain after a dive and shows no improvement during the second O2 period, what is the next step?

In the scenario presented, if a diver experiences elbow pain after a dive that does not improve during the second oxygen treatment period, consulting a Dive Medical Officer (DMO) is essential. The DMO possesses specialized knowledge and skills necessary to assess the diver's condition comprehensively.

If the pain is indicative of decompression sickness or any related diving injury, the DMO can recommend an appropriate course of action, which may include additional treatment in a hyperbaric environment, such as a Table 6 (TT6) protocol. This treatment focuses on supplying the necessary oxygen exposure under controlled conditions to facilitate recovery.

Effective management of potential diving injuries is crucial to ensure the diver's safety and prevent further complications, highlighting the importance of professional medical guidance rather than simply monitoring the situation or altering dive practices without expert input.
