WebA VO2 max test is a maximal exercise test performed on a treadmill or bike while connected to a machine capable of analyzing your expired air. Your test provides data on how much oxygen you use as you exercise and determines the maximal oxygen you can consume during exercise. This is a gold-standard measurement of endurance. WebIf ventilatory failure is suspected, ABG analysis, continuous pulse oximetry, and a chest x-ray should be done. Respiratory acidosis revealed by the ABG measurement (eg, pH < 7.35 and PCO2 > 50) confirms the diagnosis.
