How will changes in arterial P_O2 impact ventilation? Select the one most accurate response.

Group of answer choices

Small changes in arterial P_O2 will result in fine changes to V_E in order to maintain relatively stable arterial P_O2.

Arterial P_O2 will not affect ventilation unless it drops below 60mmHg.

O₂ cannot cross the blood/brain barrier, thus cannot interact with central chemoreceptors to have an impact on ventilation.

Breathing 100% O₂ at atmospheric pressure will greatly reduce the urge to breathe.
