NIBP Monitoring
Figure 13-1 Applying Cuff
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.
ZlA Note /1a
For Neonate measurement, the maximum pressure of the cuff is 147mmHg. The
maximum pressure is 140mmHg when the cuff is used normally. The initial inflating
pressure of the cuff is 70mmHg during measurement.

■ 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. 3. 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
