✍️ Sample Certified Hyperbaric Technologist Test Questions & Answers
1. Why are air breaks often incorporated into longer wound-treatment dives?
✓ To reduce the risk of oxygen toxicity while maintaining therapy
Periodic air breaks lower cumulative oxygen exposure, reducing toxicity risk during extended protocols.
2. If a fire ignites inside a monoplace hyperbaric chamber during a treatment, what is the FIRST priority action?
✓ Begin immediate emergency decompression
Immediate emergency decompression is the first priority to rapidly reduce the oxygen-enriched atmosphere and allow the patient to exit the chamber.
3. For a patient on the chemotherapy drug doxorubicin, the technologist should be aware that HBO2 may:
✓ Potentiate the drug's cytotoxic and cardiotoxic effects
Doxorubicin is a recognized HBO2 interaction concern due to enhanced toxicity.
4. After any significant in-chamber emergency, the appropriate final step for the technologist is to:
✓ Document the event thoroughly and report it per facility safety protocol
Accurate documentation and reporting support patient safety, equipment inspection, and quality improvement.
5. A sealed flexible bag holds 6 L of gas at the surface (1 ATA). At 3 ATA in a hyperbaric chamber, what is its approximate volume, assuming constant temperature?
✓ 2 L
Boyle's Law gives V2 = (P1V1)/P2 = (1 x 6)/3 = 2 L.
6. Henry's law is most relevant to hyperbaric therapy because it describes:
✓ How more oxygen dissolves in plasma under increased pressure
Henry's law states gas dissolves in liquid proportional to its partial pressure, the basis for hyperoxygenating plasma.
