Dr. Apgar, a university professor from Hamilton, is in the Swiss Alps studying astronomy during a sabbatical leave. He has been there for two days and plans to stay the entire year. During his first few days, Dr. Apgar notices that he quickly becomes breathless when walking upstairs and tires easily with any physical activity. His symptoms gradually disappear, and after two months he feels fine. Upon returning to Canada, Dr. Apgar has a complete physical exam and is told that his erythrocyte count (hematocrit) is higher than normal. Explain these findings. Will his RBC levels eventually return to normal? Why or why not?
