BIOS W100 Instruction Manual - Systolic

pressure is considered too high and other health risks including: heart attack, stroke, dementia, 

kidney failure, heart disease and erectile dysfunction may occur. It is expressed as two numbers: 

systolic/diastolic 120 mm Hg / 80 mm Hg

(mm Hg= millimeters of mercury). “Systolic” numbers refer to the pressure on the walls of your

arteries while the heart is contracting and pushing blood. “Diastolic” pressure is the lower number 

when the heart is at rest and relaxed. A simple way to understand this is to picture a garden hose. 

When the tap is turned on, the immediate pressure on the walls of the hose is the “systolic” value, 

and when the tap is turned off it is the “diastolic” number.

There are many different causes of high blood pressure. We differentiate between common primary 

(essential) hypertension, and secondary hypertension. The latter group can be ascribed to specific

organic malfunctions. Please consult your doctor for information about the possible origins of your 

own increased blood pressure values.

1.4 Normal Blood Pressure Values

Blood pressure is too high when measuring at home and you have rested, the diastolic pressure 

is above 85 mmHg or the systolic blood pressure is over 135 mmHg. If you obtain readings in this 

range, consult your doctor immediately. High blood pressure values over time can damage blood 

vessels, vital organs such as the kidney, and your heart.

With blood pressure values that are too low (i.e., systolic values under 105 mmHg or diastolic

values under 60 mmHg), consult with your doctor.
