The arterial-mixed venous oxygen difference
|
increases as a function of exercise intensity. |
||
|
does not change during exercise. |
||
|
decreases as the exercise intensity increases. |
||
|
plateaus after about 40% to 60% VO2 max. |
Homework Answers

During exercise, both QO2 and QCO2 increases as well as cardiac output, Qa. Suppose that during exercise QO2 increases to 2000 mL/min and the respiratory quotient remains at 0.8, and that Qa increases to 18 L/min. Assume that PaO2 remains at 95 mmHg, that O2 saturation is at 98% and PaO2 is 40 mmHg and that blood [Hb] = 15 g %. A. What is the total arterial content of O2? B. What is the venous content of O2? C....

(a) Find the change in entropy when 2 kg of Oxygen at 60°C are mixed with 6 kg of Nitrogen at 40°C in a rigid vessel. The initial pressure of each component is 103 kPa and remains the same for that of the mixture. (b) What is the amount of heat transferred during the mixing process? Given, Cv = 0.743 J/g. K for Nitrogen and Cv = 0.659 J/g. K for Oxygen.

Air Force servicemen and servicewomen were tested for maximal oxygen use in a 12 min distance run versus a 1.5 mile run. The participant runs on a level terrain for the prescribed distance. The technicians records the participant’s time to the closet second, the heart rate for 15 s immediately after the participant crosses the finish line and then estimate the VO2 max consumption using a Wilmore and Bergfeld fitness table. Below is listed the data for both the 12...
