Web3 jan. 2013 · Hyperoxia test is performed to demonstrate the response of the neonate’s arterial PaO 2 to 100% oxygen. Typically, if the cause for cyanosis is non-cardiac, the arterial PaO 2 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. WebVO 2 = (CO x C a) - (CO x C v) Which means that the cardiac output equation is: CO = VO 2 / (C a - C v) While in practice it can be hard to use the method by the books because of gas concentrations, the Fick determination is used with the help of an assumed value for VO 2 (oxygen consumption).
