A tender accompanies a patient on Table 6. At the end of the treatment, what decompression procedure must the tender follow?
Answer: Follow the same Table 6 decompression schedule as the patient
The tender is subject to the same pressure exposure and must follow the Table 6 decompression to prevent developing DCS.
When treating crush injury with HBO, the primary physiologic goal is to:
Answer: Decrease edema and reperfusion injury while enhancing tissue oxygenation
HBO reduces compartment edema through vasoconstriction while simultaneously delivering high oxygen levels, mitigating ischemia-reperfusion injury.
According to NFPA 99, which item is prohibited inside a Class A (multiplace) hyperbaric chamber?
Answer: Electronic devices with lithium batteries not approved for hyperbaric use
Non-approved electronic devices, especially those with lithium batteries, pose ignition risks in oxygen-enriched environments and are prohibited.
A patient with active chemotherapy using bleomycin is referred for HBO therapy. The correct approach is:
Answer: Defer HBO until bleomycin is cleared; bleomycin synergistically increases pulmonary O2 toxicity
Bleomycin markedly potentiates pulmonary oxygen toxicity and is a recognized relative contraindication that typically requires deferral.
During a multiplace chamber treatment at 60 fsw, a fire breaks out inside the chamber. What is the immediate priority?
Answer: Switch all patients to air masks and activate the fire suppression system, then decompress in a controlled manner
Switching to air masks removes the oxygen source from patients' breathing circuits while suppression systems are activated; then controlled decompression removes personnel safely.
For hyperbaric treatment of carbon monoxide poisoning, UHMS endorses treatment at what standard pressure?
Answer: 2.8 ATA (60 fsw)
The standard UHMS-approved pressure for CO poisoning is 2.8 ATA (equivalent to 60 fsw on U.S. Navy tables), typically using a modified Table 6 protocol.
Which statement best describes the difference between a 'Type I' and 'Type II' decompression sickness presentation in terms of treatment urgency?
Answer: Both types require equally urgent recompression; delay worsens prognosis for both
Both Type I and Type II DCS benefit from prompt recompression — any delay, especially in Type II, increases the risk of permanent neurological deficits.
