Question



Sue goes to the gym and after an initial warm-up, she increases her exercise level

pushing herself to maximum. At this point her heart rate is 175 beats/min and her stroke volume is 135 ml/beat. What is her cardiac output now? (1 pt)



At this point, by how many ml/min has her CO increased over her resting CO? (1 pt)




What % increase over resting is this? (Use the following equation). (1 pt)


                                   amount of increase in CO in ml/min

% increase =                                                                X 100%

     original CO (resting) ml/min

            What term is used to describe this increase in CO? (1 pt)




  1. Paul has an EDV of 132 ml and ESV of 72 and a heart rate (HR) of 75. 
  2. What is his cardiac output? (2 points)



     If Paul has his EDV go up to 140 ml while his ESV and HR remain the

    same, would his cardiac output increase or decrease? By what volume? (2 points)

Top Answer

1 cardiac output = heart ratestroke volume = 7270 = 5040 ml/minute after gym it is = 175135 = 23625... View the full answer
