Central nervous system oxygen toxicity in hyperbaric therapy is most likely to occur when oxygen partial pressure (PO2) exceeds:
Answer: 1.6 ATA
CNS oxygen toxicity risk rises sharply above a PO2 of 1.6 ATA, which is why most HBO protocols use 2.0–2.4 ATA with air breaks.
The documentation required by CMS for hyperbaric oxygen therapy includes all of the following EXCEPT:
Answer: A signed waiver from the patient releasing the facility from liability for oxygen toxicity
CMS does not require a liability waiver; it requires physician evaluation, per-session notes, and documentation of an approved indication for reimbursement.
In a monoplace chamber pressurized with 100% oxygen, what is the MOST critical fire prevention measure?
Answer: Strict exclusion of all flammable materials, synthetic fabrics, and ignition sources from the chamber
In a 100% oxygen monoplace environment, any ignition source combined with flammable material is immediately life-threatening, making exclusion protocols paramount.
Which treatment table is specifically indicated for decompression sickness Type I (pain-only) when symptoms are mild and resolved within 10 minutes of oxygen breathing?
Answer: US Navy Treatment Table 5
USN Table 5 is the shorter table designed for mild Type I DCS (musculoskeletal pain only) when symptoms respond quickly to oxygen at depth.
A patient receiving HBO therapy for a diabetic foot wound has a blood glucose of 42 mg/dL before entering the chamber. The correct action is:
Answer: Delay treatment, correct hypoglycemia, and recheck glucose before proceeding
HBO accelerates glucose metabolism and can worsen hypoglycemia; treatment must be deferred until glucose is normalized and stable.
The ASME PVHO-1 standard primarily governs:
Answer: The design, fabrication, and inspection of pressure vessels for human occupancy
ASME PVHO-1 (Pressure Vessels for Human Occupancy) sets the engineering and safety standards for hyperbaric chamber construction and certification.
After a hyperbaric facility experiences a patient loss of consciousness event inside the chamber, regulatory requirements typically mandate:
Answer: Completing an incident report, notifying the medical director, and conducting a root cause analysis
Adverse events require incident reporting, medical director notification, and systematic root cause analysis per accreditation and facility policy.
