Diving Program

Diving Medical Technician

Objective: To train NOAA Divers to understand, diagnose and treat diving injuries and maladies during a medical emergency.

A NOAA Diving Center instructor demonstrates how to operate a hyperbaric chamber

NOAA Diving Center instructor Zach Hileman demonstrates how to use the hyperbaric chamber on the NOAA Ship Hi'ialakai to students taking a Diver Medical Technician (DMT) course.

Students in this one-week intensive course learn how to become effective first line responders during a diving related incident. Students receive theoretical and practical instruction that includes the use of a hyperbaric chamber and medical mannequins. 

    Topics covered

    • Diving injuries and maladies
    • Hyperbaric chamber operations and treatment tables
    • Neurological exam
    • Foley catheters, nasogastric tubes and IV tubes
    • Advanced airway management and chest decompression


    One week


    At the end of this course, students are qualified to take the National Board of Diving and Hyperbaric Medical Technology (NBDHMT) exam and, after successful completion of the exam, to receive DMT certification.


    • EMT certification
    • Students must be medically authorized to dive.  The DMT is not required to be a NOAA diver, but must submit to the same medical standards for exposure to a pressurized environment.


    In order to maintain certification, the DMT must maintain EMT certification in order to be eligible to recertify as a DMT. Recertification requirements are set by the NBDHMT and require a combination of continuing medical education hours and clinical contact hours. These hours may overlap with the requirements to maintain EMT certification.

    Application Materials

    A training request form must be RECEIVED by the NOAA Diving Center 30 days prior to the course start date. They can be e-mailed to the Diving Center at

    If not a NOAA Diver, prospective students must also complete and submit a physical examination at the same time as their training request.
