A patient who takes disulfiram (Antabuse) is referred for hyperbaric oxygen therapy. The primary concern is that disulfiram:
Answer: Inhibits superoxide dismutase, increasing CNS oxygen toxicity risk under hyperbaric conditions
Disulfiram inhibits superoxide dismutase, reducing the patient's defense against oxygen free radicals and increasing susceptibility to oxygen toxicity.
The minimum safe distance (standoff distance) required between a hyperbaric facility and ignition sources, per NFPA 99, is primarily intended to:
Answer: Protect against fire spread if oxygen-enriched exhaust gases ignite outside the facility
Oxygen exhaust venting from hyperbaric chambers creates an oxygen-enriched zone; standoff distances prevent this enriched atmosphere from reaching ignition sources.
A diving casualty presents with mottled skin rash, joint pain, and fatigue after a multi-day liveaboard trip. These symptoms are most consistent with:
Answer: Decompression sickness Type I (cutaneous and musculoskeletal)
Mottled skin (cutis marmorata), joint pain, and fatigue represent classic Type I DCS manifestations arising from nitrogen bubble formation in superficial tissues and joints.
According to UHMS accreditation standards, the hyperbaric physician director must hold:
Answer: Physician training in hyperbaric medicine approved by UHMS or an equivalent credentialing body
UHMS accreditation requires the medical director to complete UHMS-approved hyperbaric medicine training; no specific specialty board is mandated.
In hyperbaric facilities, the primary reason for prohibiting wool and synthetic fabrics inside the chamber is:
Answer: These materials generate static electricity that can act as an ignition source in oxygen-enriched atmospheres
Synthetic and wool fabrics can generate electrostatic discharge, which is a significant ignition risk in hyperbaric oxygen environments.
When a hyperbaric facility is inspected for CMS certification, the surveyor will verify compliance with which life safety code?
Answer: NFPA 101 Life Safety Code and NFPA 99 Health Care Facilities Code
CMS requires compliance with NFPA 101 and NFPA 99 as conditions of participation for healthcare facilities, including hyperbaric units.
A hyperbaric technologist notices that a patient's transcutaneous oxygen monitor (TCOM) reading drops significantly during a 2.4 ATA oxygen session. The MOST likely clinical explanation is:
Answer: Hyperoxic vasoconstriction increasing oxygen delivery so the sensor saturates and under-reads
Hyperoxia causes peripheral vasoconstriction; the resulting decreased blood flow to the area being monitored can reduce the TCOM reading despite high systemic PO2.
