What is a blood pressure measurement?
Blood pressure is measured by inflating a cuff placed around the arm. Most people have had their blood pressure taken at some time or other. It is a simple and painless examination that gives a lot of useful information about the heart and the condition of the blood vessels.

What is measured?
The doctor measures the maximum pressure (systolic) and the lowest pressure (diastolic) made by the beating of the heart. The systolic pressure is the maximum pressure in an artery (which carries blood from the heart) at the moment when the heart is beating and pumping blood through the body. The diastolic pressure is the lowest pressure in an artery in the moments between beats when the heart is resting. Both the systolic and diastolic pressure measurements are important. The systolic pressure is measured when the doctor first hears the pulse. This sound will slowly become more distant and finally disappear. The diastolic pressure is measured from the moment the doctor is unable to hear the sound of the pulse. The blood pressure is measured in terms of millimeters of mercury (mmHg).

The trainer consists of a capacitive pressure sensor for measurement, and it follows oscillometric method. It offers a new feature that enables accurate tilt measurements of the user’s arm relative to the body, so that the arm is correctly positioned at the height of the patient’s heart.

This dynamic demonstrator is intended to study the basic fundamental building blocks required for measurement of blood pressure and heart rate. This demonstrator has several test points for measurement during experimentation process. All the building blocks are described on the front panel of the instrument.
