Answer: Increase the depth of ventilation.

In high altitude, the oxygen pressure will be much lower that makes the gas exchange rate is lower and decrease the oxygen delivery to the tissue. To counter this, the mouse will increase its depth of ventilation so there is more air inside the lungs for every inspiration.
