Certified Hyperbaric Technologist Test Hyperbaric Chamber Operations 4

Question 1

What is the recommended response to a fire alarm or smoke inside a multiplace chamber?

Accepted Answer

Activate the fire suppression deluge system and begin emergency procedures

Answer

Multiplace chambers have a deluge water suppression system that is activated as part of fire emergency protocol.

Question 2

During decompression (ascent), gas trapped in body cavities will:

Accepted Answer

Expand

Answer

Per Boyle's law, as pressure decreases on ascent, trapped gas volume increases (expands).

Question 3

Which physical gas law explains why ear and sinus barotrauma occur during pressure changes?

Accepted Answer

Boyle's law

Answer

Boyle's law relates pressure and volume, explaining how trapped gas spaces compress and expand with chamber pressure.

Question 4

Henry's law is most relevant to hyperbaric therapy because it describes:

Accepted Answer

How more oxygen dissolves in plasma under increased pressure

Answer

Henry's law states gas dissolves in liquid proportional to its partial pressure, the basis for hyperoxygenating plasma.

Question 5

Before a treatment, why must the technologist verify there are no petroleum-based products on the patient?

Accepted Answer

They are flammable in an oxygen-enriched environment

Answer

Petroleum-based lotions, makeup, and hair products are flammable and prohibited near pure oxygen.
