Certified Hyperbaric Technologist Test Hyperbaric Wound Healing 4

Question 1

A wound patient reports ear fullness and pain during compression. The technologist should first:

Accepted Answer

Slow or halt compression and coach equalization techniques

Answer

Middle-ear barotrauma is managed by pausing compression and coaching equalization (e.g., Valsalva).

Question 2

Before each wound-care dive, blood glucose monitoring is important in diabetic patients because HBO2 can:

Accepted Answer

Lower blood glucose and precipitate hypoglycemia

Answer

HBO2 tends to lower blood glucose, so pre- and post-dive monitoring prevents hypoglycemia.

Question 3

Which fire-safety practice is essential during wound HBO2 in an oxygen-enriched chamber?

Accepted Answer

Prohibiting petroleum-based products and static-generating materials

Answer

Oxygen-rich environments demand removal of petroleum products and ignition/static sources to prevent fire.

Question 4

A wound patient develops twitching, visual changes, and anxiety at depth. This most likely indicates:

Accepted Answer

CNS oxygen toxicity requiring reduction of oxygen exposure

Answer

These are signs of CNS oxygen toxicity, managed by removing the O2 source/air break and reducing exposure.

Question 5

Why are air breaks often incorporated into longer wound-treatment dives?

Accepted Answer

To reduce the risk of oxygen toxicity while maintaining therapy

Answer

Periodic air breaks lower cumulative oxygen exposure, reducing toxicity risk during extended protocols.
