  1. During a hyperbaric treatment, a patient reports ear pain that does not resolve with swallowing or yawning. What is the correct action?

    Answer: Stop compression immediately and begin slow decompression to the last comfortable depth

    If a patient cannot equalize and ear pain persists, compression must stop and the chamber should return to the last comfortable depth to prevent barotrauma.

  2. What is the minimum fire suppression requirement inside a multiplace hyperbaric chamber during operations?

    Answer: An internal deluge or sprinkler system capable of rapid chamber flooding

    NFPA 99 and PVHO standards require multiplace chambers to have an internal deluge/sprinkler system to rapidly suppress fire in the oxygen-enriched environment.

  3. A monoplace chamber is pressurized with 100% oxygen to 2.0 ATA. What is the approximate partial pressure of oxygen the patient is breathing?

    Answer: 2.0 ATA

    In a monoplace chamber pressurized with 100% oxygen, the partial pressure of O2 equals the absolute pressure — at 2.0 ATA, pO2 = 2.0 ATA.

  4. Which document governs hyperbaric facility safety standards in the United States?

    Answer: NFPA 99 Health Care Facilities Code

    NFPA 99 Health Care Facilities Code is the primary U.S. standard governing clinical hyperbaric facility safety, including chamber design, gases, and fire suppression.

  5. What is the purpose of performing a 'pressure test' on a hyperbaric chamber before a treatment session?

    Answer: To confirm integrity of seals and absence of leaks before patient entry

    A pre-session pressure test verifies that door seals, hull integrity, and penetration fittings are leak-free before a patient is placed inside.

  6. An inside attendant in a multiplace chamber notices a patient's mask has slipped off during treatment at 2.4 ATA. What should be done first?

    Answer: Assist the patient in repositioning the mask and verify seal

    The first step is to assist the patient in correctly repositioning and sealing the mask so the therapeutic oxygen dose is not interrupted unnecessarily.

  7. During decompression, a patient in a multiplace chamber develops joint pain and mottled skin. Which condition does this most likely indicate?

    Answer: Decompression sickness Type II

    Joint pain combined with skin mottling (cutis marmorata) during or after decompression are classic signs of Type II (serious) decompression sickness.
