During a hyperbaric treatment, a patient suddenly becomes unresponsive. What is the FIRST action the operator should take?
Answer: Notify the attending physician and initiate emergency communication
The first action is to notify the attending physician and initiate emergency communication so medical personnel can direct the response.
A fire is detected inside a multiplace hyperbaric chamber. After activating the fire suppression system, what is the next priority?
Answer: Begin controlled emergency decompression following established protocols
After activating fire suppression, controlled emergency decompression following established protocols balances patient safety with decompression sickness risk.
Which condition would require IMMEDIATE emergency decompression of a hyperbaric chamber?
Answer: Uncontrolled fire inside the chamber that cannot be extinguished
An uncontrolled fire inside the chamber that cannot be extinguished is a life-threatening emergency requiring immediate evacuation via emergency decompression.
What is the maximum rate of emergency ascent typically permitted in a monoplace hyperbaric chamber to minimize decompression sickness risk?
Answer: 3 psi per minute
Emergency ascent in monoplace chambers is typically limited to approximately 3 psi per minute to reduce decompression sickness risk even in emergencies.
A hyperbaric chamber technician notices a significant oxygen leak during a treatment session. What should be done FIRST?
Answer: Shut off all electrical equipment inside and outside the chamber
Eliminating ignition sources by shutting off electrical equipment is the first priority when an oxygen leak is detected to prevent fire or explosion.
During hyperbaric treatment, a patient inside a monoplace chamber reports chest pain and shortness of breath. The technician should:
Answer: Immediately begin emergency decompression and alert medical staff
Chest pain and shortness of breath may indicate a cardiac or pulmonary event requiring immediate emergency decompression and medical attention.
Which of the following is a recognized sign of oxygen toxicity CNS seizure in a hyperbaric patient?
Answer: Tonic-clonic convulsions
CNS oxygen toxicity presents with tonic-clonic (grand mal) convulsions, which is a medical emergency requiring immediate action.
