Who We Are
The NBDHMT is the long-established and respected certification organization for those who support the delivery of undersea medicine and hyperbaric oxygen therapy. The Board was introduced in 1985 and first called the National Association of Diver Medic Technicians. Its dual purpose was the formalization of DMT training standards and introduction of DMT certification. DMT training had first occurred in 1975 as a method to enhance on-site medical presence at geographically remote commercial oilfield installations. Previous efforts to incorporate training and certification into existing organization had been unsuccessful.
In 1991, the name was changed to reflect growing certification interest by hospital-based hyperbaric technicians and hyperbaric nurses. Certification in hyperbaric technology was introduced in that same year. Hyperbaric nursing certification became available in 1995.
