Question 1

What treatment pressure is most commonly used for acute carbon monoxide poisoning in hyperbaric oxygen therapy?

Accepted Answer

2.4–3.0 ATA

Answer

Standard HBO2 for CO poisoning uses 2.4–3.0 ATA to rapidly displace carbon monoxide from hemoglobin and accelerate elimination.

Question 2

The Marx protocol for mandibular osteoradionecrosis typically involves how many HBO2 treatments preoperatively?

Accepted Answer

30

Answer

The Marx protocol prescribes 30 preoperative HBO2 sessions followed by 10 postoperative sessions to promote healing in radiated bone.

Question 3

USN Treatment Table 5 is indicated for which clinical scenario?

Accepted Answer

Mild decompression sickness with complete symptom relief at depth

Answer

Table 5 is appropriate for mild DCS cases where complete symptom resolution is achieved at 60 fsw, requiring less total treatment time than Table 6.

Question 4

How long does each hyperbaric oxygen treatment session typically last for chronic wound healing indications?

Accepted Answer

90–120 minutes

Answer

Standard HBO2 sessions for wound healing last 90–120 minutes at pressure to maximally elevate tissue oxygen tensions in ischemic areas.

Question 5

Per UHMS and CMS guidelines, at what point should HBO2 efficacy be formally reassessed in diabetic foot ulcer patients?

After 20–30 treatments

Answer

UHMS and CMS guidelines recommend reassessment after 20–30 treatments to determine whether the wound is responding adequately to HBO2.
