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

Solution

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)
