Arterial blood pressure changes with atmospheric pressure and is
affected considerably by many factors, e.g. physical loads, emo-
tional state, stress, meals, etc. Medicines, drinking, smoking has
a big effect on the individual level of blood pressure. When blood
pressure is measured in hospital, the value is always higher than
that at home. Tension can have a serious effect on certain groups
of patients and is known medically as 'White coat effect' Blood
pressure will raise in low temperature, so it is better to take blood
pressure measurement in room temperature (approximately 20°C).
If device is stored in low temperature, bring up to room tempera-
ture for at least 1 hour before use or measurement could be inac-
curate. Blood pressure does vary with age and individual, and it is
recommended to write down the readings in blood pressure record
daily and check with your doctor to find out what 'normal blood
pressure' is for you.
