9.5 Setting Up the NIBP Measurement
9.5.1 Preparing to Measure NIBP
1. Power on the monitor.
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.

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.
3) Locate the cuff in such a way that the artery mark “ ” is at a location where the clearest pulsation of
brachial artery is observed.
4) The cuff should be tightened to a degree where insertion of one finger is allowed.
5) The lower end of the cuff should be 2cm above the elbow joint.
2. The patient should lie on the back so that the cuff and the heart are in a horizontal position and the most
accurate measurement is taken. Other postures may lead to inaccurate measurement.
3. Do not speak or move before or during the measurement. Care should be taken so that the cuff will not be
hit or touched by other objects. The air tube which connects the cuff and monitor should be straightway
without any tangle.
4. The measurement should be taken at appropriate intervals. Continuous measurement at too short intervals
may lead to pressed arm, reduced blood flow and lower blood pressure, and resulting inaccurate meas-
urement of blood pressure. It is recommended the measurement be taken at intervals of more than two
minutes.
