Casual Blood Pressure (CBP) Testing

Prior to a blood pressure being taken, the client should be seated quietly for 5 mins with both feet flat on the floor. No smoking or caffeine 30mins prior.

Systolic (the top reading) – is the pressure exerted on artery walls as heart contracts

Diastolic (the bottom reading) – is the pressure remaining in arteries when the heart relaxes

At least two measures should be taken and averaged out.

This short optional video shows how to take blood pressure safely:

• Full bladder can ↑ BP
