[A] You measure a patient's blood pressure to be “Z over Y.”
What is this patient's pulse pressure in units of mm Hg?
What is this patient's systolic pressure in units of
kilograms per square meter? How does that compare with the
atmospheric pressure at Earth's surface?
[C] What is this patient's diastolic pressure in units of pounds
per square inch? How does that compare with the air pressure inside
a typically inflated car tire?
[D] Does this patient have a healthy or unhealthy blood
pressure? Explain why, and if appropriate give the stage of
hypertension or hypotension of this patient.
