Which of the following would create the highest P₅₀?

Question

Quizplus · Accepted Answer

A pH of 7.40 creates a normal oxyhemoglobin dissociation curve with a P₅₀ of 27 mm Hg.A pH of 7.50 is indicative of alkalosis and will cause a left shift in the curve,lowering the P₅₀ below 27 mm Hg.A PCO₂ of 40 mm Hg is normal and will not cause a change in the P₅₀ from the normal 27 mm Hg.However,a PCO₂ of 60 mm Hg is acidotic and will shift the curve to the right,causing the P₅₀ to be greater than normal.
