Carbon monoxide poisoning

Carbon monoxide poisoning in occupational and environmental settings. Carboxyhemoglobin (COHb) measurement and interpretation, including its limitations as a severity marker after oxygen therapy. Hyperbaric versus normobaric oxygen therapy: indications, timing, and the effect on carbon monoxide elimination kinetics. Delayed neuropsychiatric sequelae and their time course. Cardiovascular effects in workers with coronary artery disease. Fetal and maternal carbon monoxide toxicokinetics in pregnant workers. Carbon monoxide and cyanide co-exposure in smoke inhalation. Altitude and endogenous carbon monoxide. Sources of occupational carbon monoxide exposure.

A worker is treated for carbon monoxide poisoning using 100% normobaric oxygen. What is the primary mechanism by which this therapy reduces the body's burden of carbon monoxide?

A.By stimulating the liver to metabolize carboxyhemoglobin into bilirubin.
B.By increasing the affinity of hemoglobin for oxygen to prevent further CO binding.
C.By increasing dissolved blood oxygen and facilitating the displacement of CO from hemoglobin.
D.By inducing hyperventilation to increase the physical exhalation of CO gas.
