2. Check the patient information area on the screen. Set a correct patient type, select a correct cuff size.
3. Connect the tube with cuff to the connector marked with “NIBP” icon on the signal input panel.
4. Select a cuff with correct size, then unfold the cuff and wrap it around the patient’s upper arm as follows:
Determine the patient’s limb circumference.
Select an appropriate cuff by referring to the limb circumference marked on the cuff. The width of the cuff
should be 40% of the limb circumference, or 2/3 of the upper arm’s length. The inflatable part of the cuff should
be long enough to encircle at least 50% to 80% of the limb. When putting on the cuff, unfold and wrap it around
the upper arm evenly to appropriate tightness.
Remember to empty the residual air in the cuff before the measurement is commenced.
Locate the cuff in such a way that the artery mark

is at a location where the clearest pulsation of brachial
artery is observed.
The cuff should be tightened to a degree where insertion of one finger is allowed.
The lower end of the cuff should be 2cm above the elbow joint.
9.5.2 Starting and Stopping Measurements
Starting and Stopping NIBP Measurements by pressing NIBP measure key “
”.
Too frequent blood pressure measurements may cause purpura, ischemia and neuropathy in the limb with the
cuff. Inspect the application site regularly to ensure skin quality and inspect the extremity of the cuffed limb for
normal color, warmth and sensitivity. If any abnormity occurs, move the cuff to another site or stop the blood
pressure measurements immediately.
9.5.3 Factors Affecting NIBP Measurement
Like common non-invasive blood pressure measurement, improper operation may cause inaccurate or blank result
or misunderstanding of the measuring information when the oscillometric method is used to take the blood pressure
measurement. These points need particular attention of the operators.
1. Requirements of the cuff:
1) Appropriate cuff should be selected according to the age of the patient.
2) Remember to empty the residual air in the cuff before the measurement is commenced.
