How will changes in arterial PO2 impact ventilation?
Select the one most accurate response.
Group of answer choices
Small changes in arterial PO2 will result in fine
changes to VE in order to maintain relatively stable
arterial PO2.
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.
Breathing 100% O2 at atmospheric pressure will
greatly reduce the urge to breathe.
