11. Glossary

Blood pressure – The pressure exerted by circulating blood
on the walls of blood vessels; constitutes one of the prin-
cipal vital signs.
Arterial blood pressure is constantly fluctuating during the
course of the cardiac cycle. The highest pressure in the
cycle is called the systolic blood pressure, and represents
the pressure in the artery when the heart is beating. The low-
est pressure is the diastolic blood pressure, and represents
the pressure in the artery when the heart is at rest. Both the
systolic and the diastolic pressure are necessary for a physi-
cian to evaluate the status of a patient's blood pressure.
Many factors such as physical activity, anxiety, stress, eating,
smoking, medication or the time of day, can influence your
blood pressure. Blood pressure is typically low in the morn-
ings and increases from the afternoon to the evening. It is on
average lower in the summer and higher in the winter.
Electromagnetic Disturbance – An interruption of the phys-
ical field produced by electrically charged objects; affects
the behavior of charged objects in the vicinity of the field.
mmHg – Millimeter of mercury, the standard unit of mea-
sure used for blood pressure measurements.
Oscillometric Methodology – A method of pressure mea-
surement using an electronic pressure sensor.
