Additional guidance - staff training, competency and compliance

Hyperbaric Technologists

Technologists may become certified as Certified Hyperbaric Technologist-CHT (eligibility after 3 months of hyperbaric experience.) For more details on duties, education, experience, training and performance expectations see topics "Certified Hyperbaric Technologist" and "Hyperbaric Chamber Operator". 

The NBDHMT Resource Manual describes the training and competencies needed to become a Certified Hyperbaric Technologists (CHT), as well as the acceptable qualifying pathways.[1] The CHT is not a licensure, but rather an additional certification beyond the individual's qualifying profession.[1] 

The acceptable qualifying pathways for CHT certification are: 
  • Respiratory Therapist
  • Physician Assistant
  • Active Duty Military Corpsman
  • EMT/Paramedic
  • Registered Nurse or LPN
  • Nurse Practitioner 
  • Physician 
In addition to the qualifying pathway the NBDHMT provides specific guidelines for training and competency for CHTs beyond the initial Introductory Hyperbaric Medicine Course. Guidelines include [1]: 
  • Be at least 18 years of age with a high school diploma or equivalent.
  • CHT applicants must have completed a National Board of Diving & Hyperbaric Medical Technology (NBDHMT) approved hyperbaric medicine introductory training course within three years of intended CHT test date.
  • As part of the clinical internship, the CHT must complete the Transcutaneous Oxygen Monitoring (TCOM) Module.
  • In order to facilitate entry for certification in hyperbaric technology, the NBDHMT has established a set of clinical internship guidelines [1]
    • Upon completion of an approved course, CHT applicants must undergo a clinical work experience of 480 hours in undersea, hyperbaric medicine or aviation medical technology. Forty (40) hours of this requirement must be a supervised direct and physically present clinical internship. The Board must be notified in writing of the name of the preceptor prior to commencing the internship. The preceptor should be either a CHT or a CHRN with a minimum of two years of undersea/clinical hyperbaric/aviation medicine experience. The Board must be notified in writing (www.CHTPreceptorshipnotificationform.com) of the name of the preceptor prior to commencing the supervised preceptorship.
    • Clinical internship guidelines provided by the NBDHMT are general in nature. They are divided into five categories, with specific topics listed for each category. The objectives for each topic are described under the heading “Internship Objectives”. Some of the topics have been expanded to include “Additional Objectives.” Interns are encouraged to achieve each of the additional objectives in whichever topics are of particular interest, or most applicable to their situation. This approach allows individuals with varied skills and backgrounds to utilize a common program of clinical training.
    • These internship guidelines are not specific to a particular facility or method of delivery of hyperbaric oxygen therapy. Rather, they provide the broadest possible subject matter so that each center can tailor these guidelines to best fit their respective resources and areas of expertise. The objective of the clinical internship is to provide the intern with a broad-based general knowledge. Each center should develop specific training material(s) with regard to precise objectives, subject matter and teaching methods.
    • For a structured framework and tool to facilitate the clinical internship, please refer to the WoundReference competency templates 'HBOT Certified Hyperbaric Technologist Internship' and 'HBOT TCOM Monitoring' in the "Competency Tool".
  • Military personnel must complete 1000 clinical hours in addition to required, approved, training received in the military (unless 480 hours of approved clinical internship can be completed at an NBDHMT approved facility)
  • Maintain a minimum 24 continuing education credits every two years with at least 12 of those specific to undersea, hyperbaric, or aviation medicine
