WebHyperoxia Test: Hyperoxia test is performed to demonstrate the response of the neonate’s arterial PaO2 to 100% oxygen. Typically, if the cause for cyanosis is non-cardiac, the arterial PaO2 will increase to ≥ 100 mmHg on exposer to 100% oxygen. However, if there is a cardiac cause for cyanosis, the PaO2 will remain below 100mmHg.
