15.6.2 Placing the NIBP Cuff
To place the NIBP cuff, follow this procedure:
1. Verify that the patient category setting is correct.
2. Connect the air tubing to the NIBP connector on the MPM module.
3. Select an appropriately sized cuff for the patient, and then wrap it around the limb directly over the patient’s
skin as follows:
a Determine the patient
’s limb circumference.
b Select an appropriate cuff by referring to the limb circumference marked on the cuff. The width of the
cuff should be 40% (50% for neonates) of the limb circumference, or 2/3 of the length of the upper arm
or the thigh. The inflatable part of the cuff should be long enough to encircle at least 50% to 80% of
the limb.
c Apply the cuff to the patient
’s upper arm or leg and make sure the Φ marking on the cuff matches the
artery location. The cuff should fit snugly, but with enough room for two fingers to be placed between
the cuff and the patient
’s arm (on adults), and loosely on neonates with little or no air present within
the cuff. Otherwise it may cause discoloration and ischemia of the extremities. Make sure that the cuff
index line falls within the range markings on the cuff.
d Middle of the cuff should be at the level of the right atrium of the heart. If it is not, you must use the
measurement correction formula to correct the measurement. For more information, see
15.8.8 Correcting the NIBP Measurements.
4. Connect the cuff to the air tubing. Avoid compression or restriction of pressure tubes. Air must pass
unrestricted through the tubing.
• A wrong cuff size and a folded or twisted bladder can cause inaccurate measurements.
• Do not apply external pressure against the cuff and air tubing while monitoring. This may cause
inaccurate blood pressure values.
• Use care when placing the cuff on an extremity used for monitoring other patient parameters.
• Do not touch the cuff or tubing during NIBP measurement.
