At a normal p02 of 100 mmHg, what would be the oxygen saturation at the distal end of the alveolar capillaries in a person with 20% hemoglobin bound to CO? What would the hemoglobin saturation of this person (Still with COHB at 20%) be at a normal systemic tissue P02 of 40 mmHg? How would the change caused by CO affect the person's ability to move oxygen into the systemic tissues?

5. This figure shows the normal hemoglobin binding curve and the same curve in the
presence of carbon monoxide. Carbon monoxide binds to hemoglobin more strongly
than oxygen, preventing oxygen binding.
