A given person has 15 g Hgb per 100 mL blood and a partial pressure of alveolar CO2 of 33 mmHg. Based on the hemoglobin saturation curve shown below, how much hemoglobin would a comparable person need to have the same amount of oxygen in his/her blood at 14,000 ft above mean sea level. Assume the person at the higher altitude has a partial pressure of alveolar carbon dioxide of 15 mmHg.
