The input items include C.O.(Cardiac output), FiO2 (Fraction of inspired oxygen), PaO2 (oxygen partial pres-
sure), PaCO2 (carbon dioxide partial pressure), Hb (Hemoglobin), CaO2 (oxygen content of arterial blood),
CvO2 (oxygen content of mixed blood), VO2 (oxygen consumption), RQ (Respiratory quotient), ATMP (Atmos-
pheric pressure), Height and Weight.
Refer to the following table for the detailed definition, unit and adjustable range of the input items.
