ENGLISH
XIX. What is blood pressure?
Blood pressure is the pressure or the force of blood flowing
against the walls of the arteries. Blood pressure is constantly
changing during the course of the cardiac cycle. Systolic blood
pressure is the highest pressure in the cycle. Diastolic blood
pressure is the lowest pressure in the cycle. Both pressure
readings, the Systolic rate and the Diastolic rate, are information
for the physician to evaluate the status of patient's blood
pressure. Many factors such as physical activities, anxieties,
time of day, can influence one's blood pressure. Blood pressure
is typically low in the morning and increases from afternoon to
the evening. It is lower in the summer and higher in the winter.
Why is it useful to measure blood pressure at home?
Because having one's blood pressure measured by a doctor
in a hospital, or clinic tends to stimulate nervousness in a
person and may cause the blood pressure to rise. Also, blood
pressure changes in different conditions, so judgment on
the basis of single measurement is not reliable. The blood
pressure measured first thing in the morning after getting up,
before taking any food is known as the fundamental blood
pressure. So it is useful to take blood pressure at home.
