As you know from our section meeting, blood pressure is measured using an inflatable
cuff and a stethoscope.
Describe how this blood pressure measurement works by
answering the following questions:
What happens in your arm as the inflatable cuff is pressurized?
Why is it usually
inflated to ~200 mmHg?
Blood pressure is recorded as (systolic pressure)/(diastolic pressure), with a
typical value of 120/80 (in mmHg).
These pressures are determined by listening
with a stethoscope as the pressure in the cuff is decreased.
