INTRODUCTION

Measurement Principle

This product uses the Oscillometric Measuring method to detect

blood pressure. Before every measurement, the unit establishes a

"zero pressure" equivalent to the air 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. Tie the cuff 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.

2. The cuff should be snug but not

too tight. You should be able to

insert one finger between the

cuff and your arm.

3. Sit comfortably with your tested

arm resting on a flat surface.

4. Patients with Hypertension:

The middle of the cuff should be

at the level of the right atrium of the heart;

Before starting measurement, please sit

comfortably with legs uncrossed,

feet flat on the floor, back and arm supported.

Rest for 5 minutes before

measuring.

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, position of upper

arm, or as directed by a physician.
