POSITIONING THE ARM CUFF
Thecuffcircumferenceisabout22-32cm.Ifyour
arm’scircumferenceis
biggerthanthis,the
cuffcannotbeused
tightlyandcause
inaccuratereading.
Ensurethearmcuff
iscorrectlyplacedtoobtain
anaccuratereading.
NOTE Ifyourphysicianhasdiagnosedyouwith poor
circulationinyourleftarm,useyourrightarm.
1. Choosethepositionfromwhichyouwishtomeasure,
sittingorlyingdown.
2. Rollorpushupyoursleevetoexposetheskin.
3. Putarmthroughthecuffloop.
4. Placecuffaboutaninch(2-3cm)aboveyourelbow.
 Usecushionsorothersupportsifnecessarytoadjust.

 Theairtubeshouldrundown,betweentheinsideof
yourforearmandthesideofyourchest,inlinewith
yourmiddlenger.
5. Fastenthearmcuffsoittssnugly.Ifthecuffistoo
loose,themeasurementwillnotbeaccurate.
PREPARING TO TAKE BLOOD PRESSURE
MEASUREMENT
Youcanchoosetotakebloodpressurewhilesittingorlying
down.Belowaresomehelpfultipsfortakingameasurement.
• Besure to set the clockbefore taking your first
measurement,orwheneveryoureplacethebatteries,so
thatthedateandtimearestoredinthememorywithyour
history.Forinstructions,refertoMonitor Settingssection.
• Itisimportanttorelaxwhentakingyourbloodpressure.
Trytotakea15-minuterestbeforeyoubegin.
• Donotleanbackwardorbendyourupperarminward
whiletakingameasurement.
• Donotsitcross-leggedandavoidtalkingormovingyour
ngersandhandwhiletakingameasurement.Rapid
movementsorotheractivitiesmayalteryourreading.
• Waitatleastanhourbeforetakingyourbloodpressure
ifyouhavejusteatenalargemeal.
• Do not smoke or drink alcohol before taking your
bloodpressure.
• Donotmeasureyourbloodpressureifyouareunderstress.
• Removeallaccessoriesfromyourarm.
BPU321OS_UM_EN_R20.indd 6 13-12-5 ��1:46

• Waitatleast3minutesbetweenmeasurements.This
allowsyourbloodcirculationtorecover.
For a meaningful comparison, try to measure under
similarconditions.Forexample,takedailymeasurements
atapproximatelythesametime,onthesamearm,oras
directedbyaphysician.

USEFUL REFERENCE
ABOUT BLOOD PRESSURE
Whatisbloodpressure?
Blood pressure is the force generated by the blood
againstthewallsofarteriesduringcardiaccontraction
andrelaxation(e.g.,thepumpingactionoftheheart).
Whataresystolicpressureanddiastolicpressure?When
ventriclescontract and pump bloodout of the heart,
bloodpressurereachesitsmaximumvalue.Thishighest
pressureinthecycleisknownassystolicpressure.When
theheartrelaxesbetweenheartbeats,thelowestblood
pressureisdiastolicpressure.
Whymeasureyourbloodpressure?
Blood pressure measurement can highly reect one’s
healthcondition.Highbloodpressureispotentiallylinked
toseriousillnessessuchasstroke,heartdiseaseand
kidneyfailure.Sincethereis nosymptommostofthe
time,manyhypertensivepeopledonotrealizetheyare
atriskuntiltheirhealthisseriouslythreatened.
Whatisthestandardbloodpressureclassication?
Thegure illustrates the blood pressure classication
madeby WorldHealth Organization (WHO) and
InternationalSocietyofHypertension(ISH)in1999.

HOW THE BLOOD PRESSURE
MONITOR WORKS
ThisproductusestheOscillometricMeasuringmethodto
detectyourbloodpressure.Beforeeverymeasurement,
theunitestablishesa“zeropressure”equivalenttothe
airpressure.
Thenitstartsinatingthearmcuffto180mmHgorhigher
untilitsensesthatithasblockedyourbloodintheartery.
Afterthat,thedeationprocessstarts,duringwhichtimethe
unitdetectspressureoscillationsgeneratedbybeat-to-beat
pulsatile,whichisusedtodeterminethesystolic,meanand
diastolicpressure, and also yourpulse rate.Any motion
duringthisperiodwillresultinanincorrectmeasurement.
Afterallreadingsaredeterminedanddisplayedonthe
LCD, the measurement is nished and the arm cuff
automaticallydeates.
