Precautions for measuring the blood pressure
• Avoid consuming alcohol, food that includes caffeine, smoking, exercising, and
taking a bath 30 minutes before measuring your blood pressure.
• Make sure your wrist is dry when measuring your blood pressure and do not measure
it when you have applied lotion or are sweating excessively.
• Do not take a deep breathe or breathe slowly on purpose, but breath as usual while
measuring your blood pressure.
• If you are pregnant, your results may not be accurate when you measure your blood
pressure.
• Do not measure your blood pressure with the Samsung Health Monitor app if you
have any of the following conditions:
– Arrhythmia
– Underlying heart disease or have suffered a heart attack
– Circulatory or peripheral vascular disease
– Valvular heart disease (Aortic valve disease)
– Myocardiopathy
– Other cardiovascular disease
– End-stage renal disease (ESRD)
– Diabetes
– Neurotic disorders (e.g. shivering)
– Hemostatic disorders or if you are taking a blood thinner
• Do not use a wrist that has been tattooed when measuring your blood pressure.
• The Samsung Health Monitor app calibrates and measures blood pressure based on
the readings from the arm that is wearing the blood pressure manometer. You must
consult your physician if there is a large difference between the blood pressure in
both of your arms (more than 10 mmHg).
• Do not use a Watch which has been calibrated for other people for measuring your
blood pressure.
• The measurable reading range of the Samsung Health Monitor app for blood
pressure is as follows: If it has been calibrated, the systolic blood pressure range is
80 mmHg to 170 mmHg, and the diastolic blood pressure is 50 mmHg to 110 mmHg.
In case of measurement, the systolic blood pressure range is 70 mmHg to 180 mmHg,
and the diastolic blood pressure is 40 mmHg to 120 mmHg.
• The signal may be affected by the individual's skin brightness, the amount of blood
under their skin, and the cleanliness of the sensor.
