CHT Treatment Protocols & Procedures 3

Question 1

A patient on insulin develops diaphoresis and confusion 45 minutes into a hyperbaric oxygen treatment. The most appropriate first response is:

Accepted Answer

Administer oral glucose and continue treatment if possible

Answer

Hypoglycemia symptoms during HBO should be treated with oral glucose; if the patient recovers, treatment may continue, but ascent is warranted if symptoms worsen.

Question 2

According to UHMS guidelines, what is the minimum number of treatments typically prescribed for a non-healing diabetic foot wound (Wagner Grade 3)?

Accepted Answer

30–40 treatments

Answer

UHMS guidelines recommend 30–40 treatments for chronic, non-healing diabetic wounds to achieve meaningful wound closure.

Question 3

During monoplace chamber operation, chamber pressure is increased to 3.0 ATA too rapidly. The patient complains of severe ear pain. The correct action is:

Accepted Answer

Halt compression, decompress slightly, and allow the patient to equalize

Answer

Stopping compression and slightly reducing pressure gives the patient time to equalize the middle ear before proceeding.

Question 4

Which treatment table is specifically designed for managing oxygen-breathing divers who surface with decompression sickness symptoms?

Accepted Answer

Table 5

Answer

Table 5 is the shorter U.S. Navy treatment table used for mild DCS in oxygen-breathing divers when symptoms fully resolve at 60 fsw.

Question 5

Fire prevention protocols in hyperbaric facilities require that oxygen concentration inside a multiplace chamber be maintained below:

Accepted Answer

23.5%

Answer

NFPA 99 and UHMS standards require ambient oxygen levels inside the chamber to stay below 23.5% to reduce fire risk.
