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.
Statement 1 is false
Statement 2 is false because
Statement 3 is true because Changes in oxygen concentration have virtually no direct effect on the respiratory center itself to alter respiratory drive .
Statement 4 is false
