1. Determine cardiac output given a heart rate of 70 beats/min and a stroke volume of 0.1
L/beat

Expert Solution

Step 1: Step 1

Cardiac output (CO) is the volume of blood that the heart pumps per minute and is typically measured in liters per minute (L/min). It can be calculated using the following formula:

$C O space equals space H e a r t space R a t e space left parenthesis H R right parenthesis space cross times space S t r o k e space V o l u m e space left parenthesis S V right parenthesis$

In our case, we have:

$H e a r t space R a t e space left parenthesis H R right parenthesis space equals space 70 space b e a t s divided by m i n space S t r o k e space V o l u m e space left parenthesis S V right parenthesis space equals space 0.1 space L divided by b e a t$
