If some tissues could extract all the 02 dissolved in arterial blood so that no 02 remained in venous blood, and if cardiac output were 5500 mL/min, then-according to the Fick principle -the VO2 (oxygen consumption or delivery of dissolved 02 to the tissues ) would be ml/min. The dissolved 02 in blood = 0.3 mL/100 mL blood. -
If the cardiac cycle is .86 sec what is the heart rate? Explanation

The following variables were measured in a 30-year-old woman during exercise: Oxygen consumption 500 ml/min Hemoglobin concentration 10 g/100 mL Mean arterial to venous oxygen concentration difference 5 mL O/100 ml blood Which of the following is the mean cardiac output (in L/min) needed to sustain oxygen delivery to tissue? A) 5 B) 6 C) 10 D) 15 E) 20
