IntroductionThe OMRON M1 Classic measures your blood pressure and pulse simply and quicklyfrom the arm, without the use of a stethoscope. The measurement values are stored inthe memory of the OMRON M1 Classic.The OMRON M1 Classic includes a standard cuff for arm circumferences ranging from22-32 cm. Optional small cuffs (17-22 cm) and large cuffs (32-42 cm) can be applied.

How to obtain meaningful blood pressure readings

General• The OMRON M1 Classic is not suitable

for measuring the frequency of cardiacpacemakers.

• Consult your doctor during pregnancy,arrhythmia and arteriosclerosis as thiscan influence the measurement.

• Avoid eating, drinking (alcohol),smoking, sport and taking a bath beforemeasurement.

• Be calm and relaxed before and duringmeasurement.

• You should never change the dose ofmedicines prescribed by your doctor.

• Store the OMRON M1 Classic in a dry,closed place with a temperaturebetween -20°C and 60°C.

• Remove the batteries if you not intendto use the OMRON M1 Classic for 3months or more.

Tips for use• Check your blood pressure at least twice

a day (before breakfast, after work).• Do not measure your blood pressure while

you are in a vehicle.• Always measure on the same arm.• Wrap the cuff around your arm before

start of measurement.

Caution• Operating temperature between 10°C

and 40°C.• Operating environment must be free

from excessive vibrations, shocks,magnetic fields, electrical noise, etc.

• Stay out of sunlight during measuring.• Keep portable phones 5 meters away

during measurement.• Do not wrap the cuff around any object

other than your arm.• Do not fold the cuff and the tube.• Do not drop the OMRON M1 Classic.

Blood circulationThe blood circulation is responsible forsupplying the body with oxygen. Bloodpressure is the pressure exerted on thearteries.The systolic blood pressure value (higherpressure or top value) represents theblood pressure produced by contraction ofthe heart muscle.The diastolic blood pressure value (lowerpressure or lower value) represents theblood pressure produced by relaxation ofthe heart muscle.

Classification of blood pressureThe World Health Organisation (WHO)and the International Society ofHypertension (ISH) developed the bloodpressure classification. This classificationis based on the blood pressure valuesmeasured while sitting on a chair in theoutpatient department of a hospital.

According to the blood pressure classification by

the WHO/ISH.

Health and blood pressureThe incidence of hypertension increaseswith age. In addition, a lack of exercise,excess body fat and high levels ofcholesterol (LDL), which sticks to theinside in blood vessels, reduces elasticityof these vessels. Hypertensionaccelerates arterial sclerosis which canlead to very serious conditions such asstroke and myocardial infarction. Forthese reasons it is very important to knowwhether the blood pressure is within ahealthy range. Blood pressure fluctuatesfrom minute to minute, throughout theday. Therefore it is essential to takeregular measurements to help you identifyan average blood pressure.

Symptoms of high blood pressureHigh blood pressure can go unnoticed fora long time, since it does not causenoticeable symptoms. The following areall possible causes of abnormally highblood pressure:• Overweight• High cholesterol level• Smoking• Excessive alcohol consumption• Stress and emotional upset• Excessive consumption of salt• Lack of physical exercise• Genetic/hereditary predisposition• Underlying illnesses, such as kidney

disorders or endocrine disturbance

enables you to recognize high bloodpressure at an early stage and obtainmedical treatment.

The oscillometric method of measurementdetermines your blood pressure bymeasuring the pressure fluctuationscaused by the pulse waves.

Since your blood pressure fluctuateswithin a day (see graphic next page), youshould always measure it at the sametime each day to ensure that themeasurements are genuinely comparable.At the doctor’s surgery, nervousness andtension may cause your blood pressure tobe higher than in familiar circumstancesat home. This is known as “White CoatHypertension”.

Treatment of high blood pressureIf your blood pressure reaches uppervalues of 140 - 160 mmHg and lowervalues of 90 - 95 mmHg in repeatedmeasurements over several days, youshould consult your doctor for detailedmedical examination. You can assist thetreatment prescribed by your doctor in thefollowing ways:

• Loose weight and lower yourcholesterol level by reducing thecalories and fat in your diet. Cut downon animal fats and eat more fruit andvegetables.

• Reduce the consumption of alcohol.• Reduce the intake of salt: the German

League for Combating High BloodPressure recommends six grams of saltper day (i.e. one teaspoon) on average.

• Stop smoking.• Take regular exercise.• Monitor your blood pressure.
