Measurement Method
HL858CB Automatic Upper Arm Blood Pressure Monitor measures
blood pressure and heart rate by oscillometric method, meaning the
fluctuations in pressureare measured. Once the cuff is wrapped
around your upper arm, just turn on the monitor and inflation
automatically starts.The inflation of the cuff creates pressure around
the arteriesinside upper arm.
Within the cuff is a gauge which senses thefluctuations (oscillations) in
pressure. The fluctuation measured represents the degree of intensity
that your arteries contracting with each heart beat,andalso aresult of
the pressure that the cuff has placed on the upper arm. The
monitormeasures these contractions and converts the informationto a
digital value. This is the result displayed on the monitorscreen.
Once the measurement is complete, the cuff will automaticallydeflate.
Accuracy
HL858CB Automatic Upper Arm Blood Pressure Monitor has been
clinically tested against a scientificdevice called
sphygmomanometer
,
considered thegold standard in blood pressure measurement.
All HL858CBAutomatic Upper Arm Blood Pressure Monitors have
performed equivalent to measurements takenwith this scientific
device and are within the accuracy limitsprescribed by the American
National Standard for Electronicor Automated Sphygmomanometers.
The SPHYGMOMANOMETER was clinically investigated according to
the requirements of ISO 81060-2:2013.
*We suggest our users have their blood pressure monitor
checked every 2 years. This operation should only be
performed by Manufacturer or by authorized representatives.
