Which item is strictly prohibited inside a monoplace hyperbaric chamber due to fire risk?
Answer: Petroleum-based lip balm
Petroleum-based products are flammable and forbidden in the oxygen-enriched chamber environment.
A patient reports a feeling of fullness and pain in the ears during compression. What is the most appropriate first action?
Answer: Stop or slow compression and coach equalization techniques
Halting or slowing compression and coaching maneuvers like swallowing or Valsalva allows middle ear equalization and prevents barotrauma.
What is the primary reason patients are grounded inside a hyperbaric chamber?
Answer: To prevent static electricity discharge that could ignite a fire
Grounding dissipates static charges that could create a spark in the oxygen-rich environment.
Which vital sign change during treatment would most strongly suggest oxygen toxicity onset?
Answer: Twitching, visual changes, or seizure activity
CNS oxygen toxicity presents with muscle twitching, visual or auditory disturbances, and seizures.
What humidity-related precaution helps reduce static fire risk in the chamber?
Answer: Keeping relative humidity above a minimum threshold
Maintaining adequate humidity reduces static electricity buildup and lowers ignition risk.
A diabetic patient is scheduled for HBO therapy. What is a key pre-treatment safety check?
Answer: Verify blood glucose level before and after treatment
HBO can lower blood glucose, so checking levels before and after prevents hypoglycemia during treatment.
Which approved garment material is acceptable for a patient entering the chamber?
Answer: 100% cotton gown
Only 100% cotton garments are permitted because synthetics can generate static and are more flammable.
