Measuring BP provides significant information about the individual’s cardiovascular system.

BP is the force exerted by the blood on the blood vessel wall, and is always expressed in Millimetres of Mercury (mmHg).

BP: Cardiac Output x Peripheral Resistance

Output-influenced by strength of the constriction on the heart
-total blood volume

Resistance -affected by-elasticity of the blood vessels
-thickness of the blood (viscosity)

Systolic Pressure

Pulse Pressure-the difference between the systolic BP and the　diastolic BP.

Hypertension-elevated arterial BP
Hypotension -a low BP in relation to the individual’s usual pressure

Normal range of BP
<1 years old 85/54
1-6y 105/65
10y 105/65
13y 110/65
adult 120/80
