A healthy young adult living on the coast at sea level attempts to climb the Himalayan Mountains, which of the following changes is expected?The alveoli Po2 decreases because of the thinner air and lower O2 composition (< 21%) in high altitude.Decreased 2,3 BPG levels which will cause a rightward shift of oxygen-hemoglobin dissociation curve to facilitate O2 loading.Decreased hemoglobin/hematocrit due to chronic hypoxia.A lower pulse oximeter reading because of a reduction in the arterial PO2.CO levels will increase in the atmospheric air

Step 1
At high altitudes, the air is thinner and has a lower O2 composition, so the alveoli Po2 will decrease. This is true. Show more…

A healthy young man living on the coast at sea level attempts to climb to a mountain peak at 14,000 feet, which of the following changes are expected? Increased respiratory rate The alveoli PO2 decreases because of lower total O2 composition (< 21%) in air at high altitude. Decreased respiratory rate Increased firing of the peripheral chemoreceptors. Decreased 2,3 BPG levels which will cause a rightward shift of oxygen-hemoglobin dissociation curve to facilitate O2 loading hemoglobin. Decreased hemoglobin/hematocrit due to chronic hypoxia. A lower pulse oximeter reading because of a reduction in the arterial PO2.
A healthy person living in the Midwest attempts to climb to a mountain peak at 14,000 feet. Which of the following changes are expected? - A lower pulse oximeter reading because of a reduction in the arterial PO2. - Decreased hemoglobin/hematocrit due to chronic hypoxia. - Decreased respiratory rate. - Increased firing of the peripheral chemoreceptors. - Decreased 2,3 BPG levels, which will cause a rightward shift of the oxygen-hemoglobin dissociation curve to facilitate oxygen loading by hemoglobin. - The alveolar PO2 decreases because of lower total oxygen composition (21% in air at high altitude). - Increased respiratory rate.
