CHS Treatment Planning & Protocols 3

Question 1

Which condition represents the only absolute contraindication to hyperbaric oxygen therapy that must be resolved before treatment begins?

Accepted Answer

Untreated pneumothorax

Answer

Untreated pneumothorax is the single absolute contraindication because increasing pressure can convert it to a life-threatening tension pneumothorax.

Question 2

Before initiating HBO2 in a patient with an implanted electronic device (e.g., pacemaker), the hyperbaric physician must verify:

Accepted Answer

The device has been tested and approved for use at the planned hyperbaric pressure

Answer

Implanted electronic devices must have documented manufacturer pressure ratings confirming safety at the intended treatment depth before HBO2 proceeds.

Question 3

A diabetic patient presents for HBO2 with a blood glucose of 340 mg/dL. The appropriate action is:

Accepted Answer

Delay treatment until glucose is better controlled

Answer

Significant hyperglycemia impairs wound healing and increases infection risk; glucose should generally be below 250 mg/dL before treatment.

Question 4

Which medication significantly increases the risk of CNS oxygen toxicity during HBO2 by inhibiting superoxide dismutase?

Accepted Answer

Disulfiram (Antabuse)

Answer

Disulfiram inhibits superoxide dismutase, a key antioxidant enzyme, markedly increasing CNS oxygen toxicity susceptibility during HBO2.

Question 5

During pressurization, a patient reports increasing ear pain and cannot equalize. The correct protocol response is:

Accepted Answer

Stop pressurization, allow equalization, then resume at a slower rate if successful

Answer

Pressurization should halt to prevent barotrauma; after successful equalization the rate can be slowed and the descent resumed.
