When pressurizing a multiplace chamber for a U.S. Navy Table 6 treatment, what is the standard compression rate?
Answer: Rate determined by patient tolerance, typically up to 20 fsw/min
Compression rate is titrated to patient tolerance, commonly up to 20 fsw per minute, pausing if equalization difficulty occurs.
In hyperbaric treatment of necrotizing fasciitis, HBO therapy is used as an adjunct primarily because it:
Answer: Inhibits anaerobic bacterial growth and enhances leukocyte killing
High tissue PO2 inhibits anaerobic organisms and restores the oxidative burst in neutrophils impaired by local hypoxia.
A patient completes a Table 6 treatment for DCS but neurological symptoms fully resolve only at depth. Per UHMS protocol, the most appropriate next step is:
Answer: Extend Table 6 at 60 fsw with additional oxygen periods
If symptoms do not fully resolve on ascent, Table 6 can be extended by adding oxygen periods at 60 fsw before ascending.
The unit pulmonary toxic dose (UPTD) is used in hyperbaric medicine to:
Answer: Quantify cumulative pulmonary oxygen toxicity exposure across multiple treatments
UPTDs accumulate with each oxygen exposure and are tracked to ensure cumulative pulmonary oxygen toxicity remains within safe limits.
Which of the following represents appropriate pre-dive patient preparation for hyperbaric oxygen therapy?
Answer: Changing into 100% cotton garments and removing all synthetic materials
Cotton garments are required because synthetic materials can generate static electricity and are flammable in high-oxygen environments.
Which clinical finding would MOST strongly indicate a need to abort a hyperbaric treatment and decompress?
Answer: Tonic-clonic seizure activity in the patient
A generalized tonic-clonic seizure is a medical emergency requiring controlled ascent and treatment termination to prevent injury.
Hyperbaric oxygen is approved by UHMS as an adjunct treatment for which type of anemia?
Answer: Anemia due to exceptional blood loss when transfusion is impossible
HBO is approved for exceptional blood loss anemia when blood transfusion is refused or impossible, providing dissolved oxygen to maintain tissue oxygenation.
