LOW BLOOD PRESSURE DIAGNOSIS

Blood pressure is measured using two numbers - the systolic first (the pressure in the arteries when the heart contracts and pushes the blood round the body) and then the diastolic (the pressure in the arteries when the heart] relaxes and fills with blood between two heart beats).
Blood pressure is measured using an inflatable cuff. This is positioned around the upper arm. The cuff is inflated and the doctor or nurse listens to the artery just below the cuff as the air is then released. When they can hear the heart beat, they will record the systolic pressure. When the sound-disappears, they will record the diastolic pressure. Sometimes an automatic blood pressure recording machine is used.
Blood pressure may be measured while lying down and then while standing. Blood pressure has to be checked regularly.
