Diving Medical Technicians (DMT) are trained in a range of advanced first aid and basic paramedical techniques.  In an emergency, the DMT may be expected to assist in the initial diagnosis, tend to the patient, administer medication and/or fluids and take control of the situation until a Diving Doctor or other medical help arrives.

IMCA certified DMT training is offered by Seneca College, Commercial Diving Institute and the Divers Institute of Technology.
