NOTE
•
If NIBP measurement fails, “XX” is displayed; if NIBP measurement is not taken, “--” is displayed.
•
Outlined NIBP numerics indicate that the measurement is old and exceeds the set time. So these
NIBP values are not recommended for reference.

Preparing for NIBP Measurements
13.6.1
Preparing the Patient for NIBP Measurements
In normal use, perform NIBP measurement on a patient who is in the following position:
■
Comfortably seated
■
Legs uncrossed
■
Feet flat on the floor
■
Back, arm and feet supported
NOTE
•
It is recommended that the patient calms down and relaxes as much as possible before performing
the measurement and that the patient do not talk during the measurement.
•
It is recommended to have the patient sat quietly for several minutes before taking the
measurement.
•
Other factors that have been shown to result in an overestimation of blood pressure are labored
breathing, full bladder, pain etc.
13.6.2
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 monitor.
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
13.8.9 Correcting the NIBP Measurements
.
(5) Measurement mode: for Auto NIBP, interval is displayed; for Sequence mode, the current phase and interval are
displayed
(6) Diastolic pressure
(7) Diastolic pressure alarm limit
(8) Mean pressure alarm limit
(9) Mean pressure (displayed after measurement completed) or cuff pressure (displayed during the measurement)
(10) Systolic pressure
