... is:15 g/dl × 1.34 ml O 2 /g Hgb = 20 .1 ml O 2 /g Hgb And the cardiac output in this patient is:QS==CI= = 2. 5 l/min/m 2 Or, combining denominators:QS== = 2. 5 l/min/m 2 The same basic formula ... hemoglobin, oxy-hemoglobin,deoxy-hemoglobin, carboxy-hemoglobin and methemo-globin. However, the various co-oximeter apparatuses are expensive and they require special hemolyzing and cleaning ... sam-ples are increased slightly to 70% in the SVC and 98% in the SA. The oxygen capacity of the hemoglobin is still 20 .1, while the SA pO 2 is 500 and the SVC pO 2 is 40.QS=== =2. 14 l/min/m 2 Thus,...
