General Description
The ZEWA Blood Pressure Monitor is a digital monitor intended for use in
measuring blood pressure and heartbeat rate with arm circumference ranging
from 22cm to 42cm(about 8¾˝-16½˝).
It is intended for adult indoor use only.
Indications for Use
Measurement Principle
Contraindications
1.The device should not be used by any person who may be suspected of,or is pregnant .
2.The device is not suitable for use on patients with implanted,electrical devices,
such as cardiac pacemakers, defibrillators.
This product uses the Oscillometric Measuring method to detect blood pressure.
Before every measurement, the unit establishes a “zero pressure” equivalent to the
atmospheric pressure. Then it starts inflating the arm cuff, meanwhile, the unit detects
pressure oscillations generated by beat-to-beat pulsatile, which is used to determine
the systolic and diastolic pressure, and also pulse rate.

tie the cuff
1.
4.
Hold your arm with your palm facing up and
on your upper arm, then position the tube off-center toward
the inner side of arm in line with the little finger. Or position
the artery mark over the main artery (on the inside of your arm).
Note: Locate the main artery by pressing with 2 fingers
approximately 2 cm above the bend of your elbow on the inside
of your left arm. Identify where the pulse can be felt the strongest.
This is your main artery.
The cuff should be snug but not too tight. You should
be able to insert one finger between the cuff and your arm.
Remove all jewelry, such as watches and bracelets
from your left arm.Note: If your doctor has diagnosed
you with poor circulation in your left arm, use your right arm.
Roll or push up your sleeve to expose the skin.
Make sure your sleeve is not too tight.
2.
3.
Sit comfortably with your tested arm resting on
a flat surface. Place your elbow on a table
so that the cuff is at the same level as your heart.
Turn your palm upwards. Sit upright in a chair,
and take 5-6 deep breaths.
5.
Rest for 5 minutes before first measurement.
Wait at least 3 minutes between measurements.
This allows your blood circulation to recover.
The patient must relax as much as possible and do not move and talk
during the measurement procedure.
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.
6.
Take the measurement in a silent room.
The cuff should maintain at the same level as the right atrium
of the heart.
Please sit comfortably. Do not cross your legs and
keep your feet flat on the ground.
Keep your back against the backrest of the chair.
