Abstract: An embodiment includes a ventilator system that corrects oxygen sensor measurements, for example derived from an oxygen sensor in a mixing chamber of an indirect calorimeter or oxygen consumption (VO2) monitoring device. In an example, an embodiment determines fractional inspired oxygen drift as supplied by a ventilator and utilizes the change or change rate in fractional inspired oxygen over time to correct VO2 determinations made by the system.
