A patient inside a monoplace chamber experiences a generalized tonic-clonic seizure during HBO2. The immediate action should be:
Answer: Protect the patient from self-injury and maintain pressure until the seizure self-terminates
Rapid decompression during an oxygen toxicity seizure risks arterial gas embolism; the seizure is self-limiting and the patient is kept safe until it ends.
Fire is discovered inside a multiplace hyperbaric chamber during a treatment session. The inside attendant's FIRST action should be:
Answer: Activate the deluge/sprinkler system and alert the outside operator
Activating the deluge system and alerting outside personnel are the first priorities; they address the fire and coordinate safe emergency decompression.
During ascent from a routine HBO2 session, a patient develops sudden chest pain and dyspnea. The most likely diagnosis is:
Answer: Pulmonary barotrauma with potential arterial gas embolism
Sudden chest pain and dyspnea during ascent are hallmark signs of pulmonary barotrauma, which can result in pneumothorax or arterial gas embolism.
The recommended ascent rate from depth in most standard hyperbaric oxygen treatment protocols is:
Answer: 1 fsw per minute
A controlled ascent rate of 1 fsw/minute is standard across most therapeutic tables to allow gas equalization and prevent barotrauma.
A patient displays twitching of the facial muscles and visual disturbances during HBO2 treatment. The correct immediate response is:
Answer: Switch the patient to an air break and notify the hyperbaric physician
Twitching and visual disturbances are VENTID signs of CNS oxygen toxicity; removing the oxygen stimulus via an air break is the first intervention.
The mnemonic VENTID is used in hyperbaric medicine to identify warning signs of:
Answer: Central nervous system oxygen toxicity
VENTID (Vision, Ears, Nausea, Twitching, Irritability, Dizziness) describes the prodromal signs of CNS oxygen toxicity preceding potential seizure.
After a fire emergency in a hyperbaric chamber is extinguished, what is required before the chamber returns to clinical use?
Answer: A complete inspection, incident report filed, and safety officer clearance
Post-fire return to service requires full structural inspection, root-cause documentation, incident reporting, and formal safety officer approval.
