Small changes in arterial Po2 will result in fine changes to VÊ in order to maintain relatively stable arterial Po2. O Arterial Po2 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. O Breathing 100% O2 at atmospheric pressure will greatly reduce the urge to breathe.arrow_forwardList the factors that shift the Oxyhemoglobin Dissociation Curve?arrow_forward
