Oxygen affinity is increased by all except_________________?
Correct answer: A. Hypoxia
- A. Hypoxia
- B. Alkalosis
- C. Increased HbF
- D. Hypothermia
Explanation
Alkalosis, hypothermia and HbF increase haemoglobin's oxygen affinity by shifting the dissociation curve to the left. Hypoxia generally promotes a right shift through increased 2,3-BPG, so it is the exception.
