Assignment:

Tore grew up in Innlandet in Norway at 1600m above sea level. He spent a majority of his youth playing outside and climbing trees. At sea level he experiences 100% saturation of his haemoglobin, and in Innlandet at 1600m he still has 98% saturation of his haemoglobin.

a) Normal haemoglobin is able to bind 1.36 mL O2 per gram of haemoglobin at 100% saturation.

How much oxygen is bound to 1 gram of Tore's haemoglobin at the altitude of 1600m? (Answer with decimals to 100ths of a mL)

b) Tore was also blessed with good genes and has 180 grams Hb per L of blood. The average male typically has 150 grams Hb/L. At sea level, how much more oxygen is carried in Tore's blood (per liter) than in an average male? (Answer in mL O2/L blood)

c) With Tore's elevated haemoglobin concentration, what change in his haemoglobin-saturation curve would you anticipate? Why?

1) Left Shift

2) No Change

3) Right Shift

4) Down Shift

d) Tore's elevated haemoglobin concentration will result in which of the following? (Choose all that apply). Why?

1) Increased dissolved oxygen in the blood

2) Delivery of more oxygen to the tissues

3) Increased dissolved carbon dioxide in the blood

4) Less carbon dioxide removed from the tissues

5) Decreased drive to ventilate when arterial PO2 falls below 60 mmHg

6) Decreased drive to ventilate when arterial PCO2 rises above 40 mmHg
