BeneVision N1 Patient Monitor Operator’s Manual 12 - 3
• If NIBP measurement fails, “XX” is displayed; if NIBP measurement is not taken or NIBP
measurement exceeds its measurement ranges, “--” is displayed.
• NIBP numerics in black color with a light outline indicate that the measurement is old and exceeds
the configured NIBP Measurement Timeout time (see section 21.5.5Setting Parameter Measurement
Timeout). These NIBP values are not recommended for reference.
12.6 Preparing for NIBP Measurements
12.6.1 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
• It is recommended that the patient remains calm and relaxes as much as possible before performing
the measurement and that the patient does not talk during the measurement.
• Other factors that have been shown to result in an overestimation of blood pressure are labored
breathing, full bladder, pain etc.
12.6.2 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
