How does pulse differ from blood pressure?
Blood pressure is the pressure the heart exerts on the walls of the arteries. Pulse is the rate at which the heart beats.
Blood Pressure
- Blood pressure is the pressure the heart exerts against the walls of the arteries as it pumps the blood out to the body
- It is measured in units of millimetres of mercury (mmHg).
- It includes two measurements:
#color(white)(m)# Systolic pressure (top number): The pressure as the heart beats and forces blood into the arteries
#color(white)(m)# Diastolic pressure (bottom number): The pressure as the heart relaxes between beats - Typical reading: 120/80 mmHg
Pulse
- Pulse (or heart rate) is the number of times your heart beats per minute.
- It is measured in units of beats per minute (bpm)
- It consists of a single measurement —the number of heart beats per minute.
- Typical reading: 60 bpm

Pulse refers to the rhythmic expansion and contraction of arteries due to the heart pumping blood through them, measured in beats per minute. Blood pressure, on the other hand, is the force exerted by the blood against the walls of the arteries, measured in millimeters of mercury (mmHg) and typically expressed as two numbers: systolic pressure (when the heart contracts) over diastolic pressure (when the heart relaxes).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
