A patient presents with arterial gas embolism following central line insertion. After initial stabilization, what treatment table is most appropriate?
Answer: US Navy Treatment Table 6A or extended Table 6
AGE is treated like severe decompression sickness; Table 6A or an extended Table 6 with oxygen extensions is preferred when symptoms are serious or fail to resolve.
When evaluating a wound for HBO eligibility using TcPO2, measurements should ideally be taken with the probe placed:
Answer: On periwound skin 1–3 cm from the wound edge
Periwound TcPO2 measured 1–3 cm from the wound margin provides the most clinically relevant oxygen tension data for predicting healing potential.
A pediatric patient requires HBOT for carbon monoxide poisoning. Compared to adults, which adaptation is most important for pediatric HBO treatment?
Answer: Providing appropriate-sized masks and ensuring close monitoring for agitation
Pediatric patients require appropriately sized equipment and heightened monitoring for agitation or anxiety, which can interfere with treatment and increase oxygen toxicity risk.
Which of the following best explains why patients with emphysema are at elevated risk during hyperbaric oxygen therapy?
Answer: Bullae may rupture during pressurization, causing pneumothorax
Emphysematous bullae can trap gas and rupture with pressure changes, creating a risk of pneumothorax or air embolism during compression or decompression.
A patient on high-dose corticosteroids is referred for HBO therapy for a crush injury. What specific concern does steroid use raise in the hyperbaric setting?
Answer: Steroids reduce the effectiveness of HBO-mediated angiogenesis and wound healing
Corticosteroids impair fibroblast activity and angiogenesis, potentially blunting the wound-healing benefits of HBO therapy.
During the consent process for HBOT, a patient asks about the risk of fire. What is the most accurate response?
Answer: Fire risk exists but is minimized by strict control of ignition sources and oxygen-safe materials
Enriched oxygen environments significantly increase combustibility; fire risk is managed — not eliminated — through rigorous exclusion of ignition sources and use of approved materials.
A patient completing their 30th HBO session for radiation-induced osteoradionecrosis reports no improvement in pain or wound size. What is the most appropriate next step?
Answer: Reassess treatment goals, surgical candidacy, and consider multidisciplinary review
Lack of response after 30 sessions warrants comprehensive reassessment including surgical evaluation, as osteoradionecrosis often requires combined surgical and HBO management.
