Question

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

Answer 1

if the stroke volume of the left ventricle is 63 mL/ beat and the stroke volume of the righ ventricle is 66 mL/beat, what will happen to the relative distribution of blood in the systemic and pulmonary circulation after 15 beats

answer:

Here we can see with each beat, the left side will get "behind" by 3 mL(66-63= 3) and It generally leads to congestion in the pulmonary circuit. So as per question , after 15 beats, the deficit will be total (15 * 3) = 45 mL of extra fluid in the pulmonary circuit. This could be the beginning of congestion and it is therefore very dengerous for congestive heart failure.

CALCULATION:

Left Ventricle
CO = HR x SV = 15 x 63 = 945 ml/minute

Right Ventricle
CO = HR x SV = 15 x 66 = 990 ml/minute

SO THE TOTAL DIFFERENCE IS 45 WHICH IS THE EXTRA VOLUME AND IT LEADS TO REDUCE THE BODY'S ABILITY TO FUNCTION CORRECTLY . ( ANSWER)
