Relationship between stroke volume ,cardiac output and heart rate is ,
Cardiac output= stroke volume × heart rate
= 80bpm× 150ml/ beat
= 12000ml/ min = 12 l/min
Option B is correct
The cardiac output, if the HR is 80 bpm and the stroke volume is 150 ml/beat,...
2 poin QUESTION 3 The cardiac output for an individual with a HR of 102 bpm and stroke volume of 110 ml/beat would be approximately A 11 liters/min B. 14 liters/min C. 17 liters/min D. 22 liters/min
3. Define Cardiac Output. 4. If the stroke volume is 75 ml/beat and heart rate is 70 beats/min, calculate the cardiac output in L/min.
If the stroke volume of the left ventricle is 63 mL/beat and the stroke volume of the right ventricle is 66 mL/beat, what will happen to the relative distribution of blood in the systemic and pulmonary circulation after 15 beats? Explain, show calculations
A. Your patient has an EDV of 150 ml/beat and an ESV of 130 ml/beat. His HR is 160 bpm. What is his CO? Is it normal? Show your work, indicate proper units, and circle your answer. (You will need to know your two cardiac equations to figure this out.)
14). What is the difference between stroke volume and cardiac output? 15). What factor(s) influence stroke volume? 16). What factor(s) influence cardiac output? 17). What is the Frank Starling Law? 18). What factors influence end-diastolic volume? 19). What enzymes determine contractility of cardiac muscle? 20). How would you increase contractility of the heart at the molecular level?
5. Consider the following equation: Stroke volume = cardiac output / heart rate If a heart fills up to 200ml of blood before contraction, and leaves 50ml in the heart after contraction, what would be the stroke volume? If the heart rate is 80 beats per minute, what would the calculated cardiac output? If the total peripheral resistance increases, what is likely to happen to the stroke volume? (Please address all three questions and include units to receive full credit.)...
Steve is a runner with a target heart rate of 135 bpm. His resting pulse is 70 bpm. His blood volume is approximately 6.8 liters. At rest, his cardiac output is 63 tr/min A What must his stroke volume be? B. What is his EDV if his ESV is 50 ml? C. During his workout, his heart rate increases to 136 born and his cardiac output to 13,500 mL/min. Did his SV change with exercise? If his EDV is 160...
