A wound patient reports ear fullness and pain during compression. The technologist should first:
Answer: Slow or halt compression and coach equalization techniques
Middle-ear barotrauma is managed by pausing compression and coaching equalization (e.g., Valsalva).
Before each wound-care dive, blood glucose monitoring is important in diabetic patients because HBO2 can:
Answer: Lower blood glucose and precipitate hypoglycemia
HBO2 tends to lower blood glucose, so pre- and post-dive monitoring prevents hypoglycemia.
Which fire-safety practice is essential during wound HBO2 in an oxygen-enriched chamber?
Answer: Prohibiting petroleum-based products and static-generating materials
Oxygen-rich environments demand removal of petroleum products and ignition/static sources to prevent fire.
A wound patient develops twitching, visual changes, and anxiety at depth. This most likely indicates:
Answer: CNS oxygen toxicity requiring reduction of oxygen exposure
These are signs of CNS oxygen toxicity, managed by removing the O2 source/air break and reducing exposure.
Why are air breaks often incorporated into longer wound-treatment dives?
Answer: To reduce the risk of oxygen toxicity while maintaining therapy
Periodic air breaks lower cumulative oxygen exposure, reducing toxicity risk during extended protocols.
A patient taking disulfiram (Antabuse) is scheduled for wound HBO2. The concern is that disulfiram may:
Answer: Block superoxide dismutase, impairing protection against oxygen toxicity
Disulfiram inhibits superoxide dismutase, theoretically increasing oxygen-toxicity vulnerability.
Adequate hydration is encouraged before wound HBO2 mainly because dehydration can:
Answer: Increase susceptibility to decompression issues and hypoglycemia
Hydration supports circulation and reduces risks like decompression problems and hypoglycemia.
