Given information

Given in the question is a physician judges the health of a heart by measuring the pressure with which it pumps blood.

And he mistakenly attaches the pressurized cuff around a standing patient's calf instead of the arm.

That is about   below the heart

We need to find what error would be introduced in the heart's blood pressure measurement.

Step-by-step explanation

Step 1.

 

is the sum of atmospheric pressure

 

The equation for the gauge pressure is,

 

 density of the fluid

 acceleration due to gravity

depth

So, rewrite equation 

 

From above it is clear that the pressure varies with the depth.
