LifeLine®Kärdio Blood Pressure Monitor
Blood Pressure Measurement
How does Blood Pressure Arise?
Blood pressure is determined in a part of the brain, referred to as the circulatory
centre which adapts blood pressure to the respective situation via feedback from
the nervous system.
Bloodpressureissubsequentlyadjustedbythecirculatorycentrebyalteringthe
heart rate (Pulse), its strength and the diameter of circulatory blood vessels by
fine muscles in the blood vessel walls.
The level of arterial blood pressure changes with heart activity. When blood is
expelledfromtheheartandintothebody,thebloodpressurevalueisatitsmaximum
and denoted as the systolic blood pressure (SBP). After the ejection of blood is
completed the heart begins a rest period known as Diastole where blood pressure
is at its lowest value and denoted as the diastolic blood pressure (DBP). Blood
pressure values must lie within a normal range to prevent cardiovascular diseases.
Normal Blood Pressure Values
Blood pressure is too high, if at rest, the diastolic pressure is above 90mmHg
and/orthesystolicbloodpressureisover160mmHg.Pleaseconsultwithyour
doctor as continuing high values endanger human health due to the progressive
damage caused to the blood vessels in the body.
Ifthesystolicbloodpressurevaluesliebetween140mmHgand160mmHgand/or
the diastolic blood pressure values lie between 90mmHg and 100mmHg, please
consult your doctor.
Withbloodpressurevaluesaretoolow,i.e.systolicvaluesunder100mmHgand/
or diastolic values under 60 mmHg, consult your doctor. Even with normal blood
pressure values, regular self-monitoring of blood pressure is recommended to
allow early detection of changes in blood pressure values and provide time to
address all medical issues appropriately.
If you are undergoing medical treatment to control your blood pressure, keep
a record of your blood pressure by performing regular self-measurements at
specific times of the day. Show these values to your doctor.

Further Information
• Ifyourvaluesarenormalunderrestingconditionsbutexceptionallyhigh
under conditions of physical or psychological stress, it is possible that
you are suffering from “labile hypertension”. Consult your doctor if you

• Ifthesystolicanddiastolicbloodpressuresfallintonon-corresponding
categories, the higher category determines the hypertensive risk. For

The Measurement Procedure
Before Starting
Avoideating,smokingandallformsofexertionorexercisedirectlybeforetaking
a measurement, as all these factors will influence the result. It is important that
prior to beginning a measurement, that you sit comfortably in a quiet room and
relaxforseveralminutes.
• Alwaysmeasureonthesamearm(normallytheleftarm).
• Tryandtakemeasurementsregularlyatthesametimeofday,sinceblood
pressure changes during the day.
iNote: To obtain meaningful measurements for comparison, a set time
to do readings should be chosen to minimise the influence exerted
by the body’s circadian rhythm over blood pressure.
Sources of Measurement Error
• Anyefforttosupport thearm during measurementcanincreaseblood
pressure.Ensureyouareinarelaxedpositionanddonottenseanyofthe
muscles in the arm during the measurement. Use a cushion to support
the arm if necessary.
• Theperformanceofautomatedsphygmomanometerscanbeaffectedby
extremesoftemperature,humidity,andaltitude.
• Avoidcompressionorrestrictionofthebloodpressurecuff’sconnection
tubing during measurement.
• Ensurethebloodpressurecuffiscorrectlyttedtothearm.Aloosecuff
causes errors or false measurement values.
• When measurements are excessively repeated, blood accumulates in
the arm, which can lead to false results. Blood pressure measurements
should only be repeated once and thereafter a 5-minute pause should be
taken to allow proper resumption of the circulation.
• Donotusethemonitornearstrongelectromagneticeldssuchasmobile
telephones, microwaves, etc.
