If a diver exceeds the bottom time listed in the decompression table, whom should they contact for advice?

Contacting the Navy Experimental Diving Unit (NEDU) is the most appropriate action if a diver exceeds the bottom time indicated in the decompression table. NEDU specializes in diving medicine and decompression physiology. They are equipped with the expertise necessary to provide guidance on managing potential issues related to exceeding safe dive limits, including recommendations for decompression procedures or any medical evaluations needed.

In situations where time limits are exceeded, it is essential to seek advice from professionals who have in-depth knowledge of the implications and risks involved. NEDU can offer evidence-based recommendations and support that are critical for ensuring the diver's safety and health.

Other options may not provide the specific expertise that is required in this case. Local dive shops or personal instructors may not have the same level of specialized knowledge in emergent decompression scenarios, and while emergency services can assist in medical emergencies, they may not be able to provide the specialized diving-specific insight necessary for decompression issues. Thus, reaching out to NEDU represents the safest choice for obtaining the correct guidance in this context.
