Question

Quizplus · Accepted Answer

Both an increase in arterial PCO2 and a right shift in the oxyhemoglobin dissociation curve would not be beneficial for a mountain climber at high altitudes. Increased arterial PCO2 could impair oxygen delivery, and a right shift in the oxyhemoglobin dissociation curve means oxygen is more readily released from hemoglobin, which could be disadvantageous in low oxygen environments.
