Complete Set; Recommendations On Correct Measurements - Nissei WS-820 Instruction Manual

OPERATION PRINCIPLES
The device uses the oscillometric method of measurement. Connect a cuff to an electronic unit and
wrap it around your wrist. When you press the « » button the device starts the automatic infl ation,
which is followed by the blood pressure measurement.
The sensor element of the device detects slight pressure oscillations in the cuff produced by the ex-
pansion and contraction of the brachial artery in response to each heartbeat. Rhythm and amplitude
of the pressure waves are measured and displayed on the LC display as a numerical value in millim-
eters of mercury. The device has an irregular pulse rhythm indicator, as well as two memories with
30 cells in each calculating the average value.
NISSEI New Technologies
IQ SYSTEM is an intelligent system developed by NISSEI engineers with due regard for
the specifi c nature of each person's heartbeat, thus providing high accuracy of read-
ings within minimal measurement time.
Irregular pulse rhythm indicator is a special icon on the display that informs on the
irregular heartbeat, while the measurement result is correct. Please be noted that the
irregular pulse can be caused by arrhythmia. To control this at an early stage we rec-
ommend you visit your doctor.
M-Cuff series is a unique cuff unit designed and patented by NISSEI. M-shaped cuff
"M" CUFF can read pulse wave simultaneously from two arteries.
WS-820 is the most accurate instrument following up the results of the tests held by
the German Hypertension Society*. About 40 devices of diff erent manufacturers were
tested both on wrist and upper arm, and WS-820 got the highest score in terms of
accuracy as of August 2006.

RECOMMENDATIONS ON CORRECT MEASUREMENTS

1 If treated with hemodialysis or anticoagulants, antiplatelets or steroids, refer to your doctor about
the blood pressure measurement. Use of this instrument under such conditions could cause internal
bleeding.
2 Malfunctions are possible when the device is used near working mobile phones, microwave ovens
and other equipment generating electromagnetic radiation (e.g. The product should be used 3.3m
away from the wireless communication device with a maximum output power of 2W).
3 Do not use this product along with implantable and wearable medical electrical equipment such
as pacemaker, defi brillator, or electrocardiographic monitor. This product is not also intended to
be used with HF surgical equipment as the use with such equipment may cause the malfunction
of the product.
