Question

If the duration of lub sound is 0.7sec stroke volume is 70ml Calculate the carduac output​

Answer 1

Answer:

Cardiac output is defined as the blood pumped by left ventricle into aorta or from right ventricle into pulmonary artery per minute.

Cardiac output is calculated as: Stroke volume x heart rate

In the question, stroke volume is given 70 ml and heart rate is given 72 beats/min

Therefore, cardiac output = 70 x 72 = 5040 ml/min

So, the correct answer is '5040 ml/min'.

I hope this answer helpful for you.
