BLOOD PRESSURE Q&A
Q Why is the blood pressure measured at home different from that measured by
the physician or at a hospital?
A Your blood pressure may vary due to exercise, the ambient temperature or
your mental state. When you have a physician or nurse measure your blood
pressure, the pressure value is likely to be 10 to 20 mmHg higher than usual
due to anxiety and/or stress. Knowing what affects your blood pressure helps
you to better monitor your health.
Q Why does the blood pressure obtained vary with measurement?
A Our blood pressure is adjusted by the function of automatic nerve. Blood
pressure differs with every heart beat. We are likely to think that our blood
pressure is constant, but it varies if you take measurements in repetition.
Blood pressure is susceptible to the time of day, such as forenoon and
afternoon, season and atmospheric temperature. In addition, blood pressure
is easily affected by mental stress or emotional ups and downs. It tends to
increase when you feel tension or decrease when you are relaxed.
Q What is the benefit of measuring my blood pressure at home?
A Blood pressure measurements taken at home give reliable data as they can
be taken when you are in a stable and relaxed condition. Physicians place
considerable importance on blood pressure measurements taken at home.
You should measure your blood pressure at the same time each day and
record the variations in your blood pressure.
Always consult your physician for an interpretation of your
blood pressure readings and to determine the proper
treatment.
