During hyperventilation, arterial $\mathrm { P } _ { \mathrm { CO } _ { 2 } }$ levels decrease because CO? is blown off more rapidly than it is being produced in the tissues.

Question

Quizplus · Accepted Answer

During hyperventilation, the rate of breathing increases, resulting in a decrease in arterial $\mathrm {P_{CO_2}}$ levels. This happens because more CO₂ is expelled from the lungs with each breath, which creates a respiratory alkalosis. The decrease in $\mathrm {P_{CO_2}}$ levels is due to faster elimination of CO₂ than production in the tissues.
