A hyperbaric chamber technician (CHT) operates pressurized chambers, monitors patients during HBOT sessions, and manages emergency protocols. Certification requires completing a 40-hour NBDHMT-approved course plus a minimum of 480 supervised clinical hours. Median pay in the U.S. sits around $45,000-$55,000 annually, with higher rates at wound care centers and military facilities.
CHT Certification Requirements
The CHT (Certified Hyperbaric Technologist) is the primary certification for non-nursing hyperbaric chamber operators in the US. Administered by the NBDHMT.[1]
Step 1: Qualifying Healthcare Credential
CHT requires holding one active qualifying credential:
- Respiratory Therapist (RT)
- Physician Assistant (PA)
- Active Duty Military Corpsman
- EMT or Paramedic
- Registered Nurse (RN) or Licensed Practical Nurse (LPN)
- Nurse Practitioner (NP)
- Physician
If you do not hold a qualifying credential, the most accessible path is obtaining EMT certification first, then pursuing CHT.
Step 2: 40-Hour Introductory Course
Complete a 40-hour minimum introductory course approved by NBDHMT, UHMS, or ACHM. The UHMS-standard curriculum covers:
- Physics of hyperbaric exposure
- Mechanisms of hyperbaric oxygen at the cellular level
- UHMS accepted indications and protocols
- Side effects and contraindications
- Patient assessment and management
- Monoplace and multiplace chamber systems
- Safety and emergency procedures
- Hands-on training and simulation
The 40-hour course takes approximately one week. Providers include Wound Education Partners (live, multiple US locations) and HBOT USA (thehbotcourse.com, online, self-paced). Course cost ranges from $500–$2,000+ depending on provider and format.
Step 3: Clinical Hours
Complete an internship or preceptorship of 100+ supervised clinical hours at a hyperbaric facility. The UHMS recommends certification within 18 months of beginning hyperbaric work.
Step 4: Board Exam
Pass the NBDHMT CHT certification exam. Exam/recertification fee: approximately $100.
CHT vs CHRN: What Is the Difference?
| Feature | CHT | CHRN |
|---|---|---|
| Full name | Certified Hyperbaric Technologist | Certified Hyperbaric Registered Nurse |
| Prerequisites | RT, EMT, PA, or similar qualifying credential | Active RN, LPN, or NP license |
| Focus | Technical operations, chamber management, safety, inside attendant duties | Nursing patient care in hyperbaric settings plus technical skills |
| Recertification | Every 2 years; 24 CE hours + 100 clinical hours | Every 4 years; 60 CE hours (30 Category A) |
| Issuing body | NBDHMT | NBDHMT |
Continuing Education Requirements
CHT recertification every 2 years requires:[1]
- 24 CE hours minimum total
- At least 12 Category A hours (hyperbaric-specific: barotrauma management, CNS oxygen toxicity, decompression procedures, chamber safety, emergency procedures)
- Remaining hours may be Category B (related topics)
- 100+ documented clinical work hours
- $100 recertification fee
Category A topics specifically include: barotrauma management, CNS oxygen toxicity, infection control, decompression procedures, tissue oximetry, and chamber safety and emergency procedures. These are the competencies that directly protect patient safety.
Facility Accreditation: What to Look For as a Patient
When choosing an HBOT provider, look for facilities with both certified staff and facility accreditation:
UHMS Hyperbaric Facility Accreditation (HFA): The gold standard. 267+ facilities hold this accreditation. It is the only hyperbaric-specific accreditation recognized by The Joint Commission and is recognized as a Complementary Accrediting Organization.[2] Ask any facility directly: “Are you UHMS-accredited?” A legitimate clinical facility will have a straightforward answer.
NFPA 99 compliance: Every clinical facility must comply with NFPA 99 Chapter 14 for construction, fire suppression, ventilation, and safety systems. CMS currently references the 2012 edition; the 2024 edition is the current standard.
Staff credentials: Ask whether the technicians operating the chamber hold CHT or CHRN certification. UHMS recommends at least one certified staff member present during all chamber operations.
Frequently Asked Questions
Can anyone operate a hyperbaric chamber?
No. CHT certification requires a qualifying healthcare credential, specific training, supervised clinical hours, and passing a national board exam. Anyone operating a clinical chamber without this foundation is not meeting the professional standard. For home wellness chambers, there is no equivalent requirement, which is part of why home use carries additional patient responsibility for safety protocols.
Do technicians need a medical degree?
No. EMTs and paramedics can qualify for CHT. A physician oversees the program and manages medical decisions, but does not need to operate the chamber during sessions. The technical operation is within the CHT scope of practice.
How much do hyperbaric technicians earn?
Hyperbaric technicians in the US typically earn $45,000–$75,000 annually depending on experience, location, and facility type. Hospital-based positions generally pay more than standalone wellness clinics. CHT certification typically commands higher compensation than non-certified positions.
