Notes on use
1. It is important to mention that arterial blood pressure is subject to substantial fluctuations. Arterial blood
pressure measurements depend on numerous factors. Blood pressure generally tends to be lower in sum-
mer and higher in winter. Arterial blood pressure changes with the atmospheric pressure and is significantly
affected by numerous factors. For example physical exertion, emotional excitability, stress, meals etc. med-
ication, alcohol and tobacco can significantly affect the blood pressure of a person. If the blood pressure
is measured in the hospital, the reading is generally higher than at home. This is particularly severe with
patients; in the medical field, this phenomenon is known as white coat hypertension. Blood pressure in-
creases at low temperatures, which is why it is better to measure blood pressure at room temperature (ap-
proximately 68 °F (20 °C)). If this device is stored at low temperatures, it must be stored at room temperature
for at least 1 hour before taking the measurement. Otherwise it may not be accurate. The blood pressure
varies depending on the age and person; it is recommended to write down the individual blood pressure
measurements on a daily basis so that you can consult your physician to determine which blood pressure is
normal for you.
