Certified Hyperbaric Technologist Test Hyperbaric Chamber Operations 2

Question 1

During a monoplace chamber treatment, the chamber is pressurized and ventilated using which gas?

Accepted Answer

100% oxygen

Answer

A monoplace chamber is typically compressed with 100% oxygen, so the patient breathes the chamber atmosphere directly.

Question 2

What is the primary reason cotton garments are required for patients inside a hyperbaric chamber?

Accepted Answer

They reduce static electricity and fire risk

Answer

Cotton minimizes static discharge that could ignite the oxygen-enriched environment, reducing fire hazard.

Question 3

In a multiplace chamber, how is hyperbaric oxygen most commonly delivered to patients?

Accepted Answer

Via a mask, hood, or endotracheal tube

Answer

Multiplace chambers are pressurized with air, and patients breathe oxygen through a mask, hood, or tube.

Question 4

What does the term 'descent' refer to in a hyperbaric treatment?

Accepted Answer

Increasing chamber pressure (compression)

Answer

Descent is the compression phase where pressure increases, simulating going deeper underwater.

Question 5

A common treatment pressure for routine wound-care hyperbaric therapy is approximately:

Accepted Answer

2.0 to 2.5 ATA

Answer

Most elective HBO protocols use 2.0 to 2.5 atmospheres absolute for wound healing.
