✍️ Sample Certified Hyperbaric Technologist Test Questions & Answers
1. Why are air breaks often incorporated into longer wound-treatment dives?
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?
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:
Doxorubicin is a recognized HBO2 interaction concern due to enhanced toxicity.
4. 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?
Boyle's Law gives V2 = (P1V1)/P2 = (1 x 6)/3 = 2 L.
5. Which type of hyperbaric chamber allows multiple patients to be treated at once?
A multiplace hyperbaric chamber is specifically designed to accommodate several patients simultaneously, along with medical staff. These chambers are typically pressurized with compressed air, and patients breathe 100% oxygen through individual hoods or masks. This setup allows for continuous monitoring and direct intervention by attendants inside the chamber, enhancing patient care and safety.
6. What does the term 'sea level equivalent' refer to during a hyperbaric treatment?
Treatment pressures are commonly expressed as a depth equivalent referenced to sea level.
