NOTE:
The width of the cuff should be either 40 % of the limb circumference (50% for neonates)
or 2/3 of the upper arm length. The inflatable part of the cuff should be long enough to
encircle 50% ~ 80% of the limb. The wrong size of cuff can cause erroneous readings. If
the cuff size is in question, then use a larger cuff.

The lifespan of cuff is: 480mmHg/20000 times; 300mmHg/50000 times.
■ Make sure that the cuff edge falls within the range of mark <－>. If it does not, use a larger
or smaller cuff that fits better.
5. Connect the cuff to the air hose. The limb chosen for taking the measurement should be
placed at the same level as the patient's heart. If this is not possible you should apply the
following corrections to the measured values:
■ If the cuff is placed higher than the heart level, add 0.75 mmHg (0.10 kPa) for each inch of
difference.
■ If it is placed lower than the heart level, deduct 0.75 mmHg (0.10 kPa) for each inch of
difference.
6. Press the NIBP START/STOP on the front panel to start a measurement. You can also stop
this measurement by pressing this button.
