Question 1

In a monoplace chamber, the most significant limitation during a medical emergency compared with a multiplace chamber is:

Accepted Answer

No attendant inside to provide hands-on care during treatment

Answer

Because no caregiver is inside a monoplace chamber, emergencies often require decompression to reach the patient.

Question 2

What is the primary rationale for an emergency decompression procedure during an unmanageable in-chamber crisis?

Accepted Answer

To allow direct access to the patient for resuscitation or evacuation

Answer

Emergency decompression is performed to physically reach and treat a patient who cannot be managed at depth.

Question 3

A patient on the deck of a multiplace chamber suffers cardiac arrest at treatment depth. The inside attendant should:

Accepted Answer

Begin CPR immediately while the team coordinates decompression

Answer

CPR is started immediately at depth while a controlled decompression and evacuation are coordinated.

Question 4

Confined-space considerations make which routine resuscitation tool potentially hazardous inside a hyperbaric chamber?

Accepted Answer

Standard electrical defibrillator used improperly in the high-oxygen environment

Answer

Electrical equipment and the oxygen-rich atmosphere create a fire and ignition risk requiring chamber-approved procedures.

Question 5

A rapid loss of chamber pressure (explosive decompression) most immediately threatens occupants with:

Accepted Answer

Pulmonary barotrauma and arterial gas embolism

Answer

Sudden pressure loss causes lung overexpansion injury and can drive gas bubbles into the arterial circulation.
