CHS Emergency Procedures & Response 3

Question 1

A patient in a monoplace chamber indicates ear pain at 20 fsw and cannot equalize. The correct procedure is to:

Accepted Answer

Hold depth, coach equalization, and decompress if unsuccessful

Answer

The chamber should be held at current depth while equalization maneuvers are coached; if unsuccessful, decompression to surface is required to prevent tympanic membrane rupture.

Question 2

Which of the following items is considered an absolute contraindication to entering a hyperbaric chamber as a patient?

Accepted Answer

Untreated tension pneumothorax

Answer

An untreated tension pneumothorax is an absolute contraindication because compression will worsen it and decompression will cause catastrophic expansion.

Question 3

During decompression, a multiplace chamber patient reports joint pain in the right knee. This presentation most likely indicates:

Accepted Answer

Type I decompression sickness

Answer

Joint pain (the 'bends') appearing during or after decompression is the hallmark symptom of Type I decompression sickness, affecting musculoskeletal and lymphatic systems.

Question 4

The primary purpose of the oxygen air break during hyperbaric oxygen therapy is to:

Accepted Answer

Reduce the risk of central nervous system oxygen toxicity

Answer

Periodic air breaks interrupt continuous oxygen exposure and significantly reduce the cumulative risk of CNS oxygen toxicity seizures.

Question 5

In a hyperbaric emergency requiring CPR inside a multiplace chamber, rescuers must know that:

Accepted Answer

External defibrillation is contraindicated in oxygen-enriched environments

Answer

Defibrillation in an oxygen-enriched hyperbaric environment poses an extreme fire and explosion hazard and must not be performed inside the chamber.
