Final answer:
Hyperbaric oxygen therapy is the recommended treatment protocol for individuals with a COHgb level surpassing 25% to aid in oxygenation.
Step-by-step explanation:
For individuals with a COHgb level surpassing 25% to aid in oxygenation, the recommended treatment protocol is hyperbaric oxygen therapy. Hyperbaric chambers increase the atmospheric pressure, causing more oxygen to diffuse into the bloodstream, which helps displace carbon monoxide from hemoglobin. Hyperbaric oxygen therapy is used in a variety of medical problems, including wound healing, anaerobic bacterial infections, and carbon monoxide poisoning.
