13.6 NIBP Measurement Procedure
13.6.1 Preparing the Patient
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 and arm supported
■
Middle of the cuff at the level of the right atrium of the heart
NOTE
•
It is recommended that the patient relaxes as much as possible before performing measurement
and that the patient does not talk during NIBP measurement.
•
It is recommended that 5 min should elapse before the first reading is taken.
•
A wrong cuff size and a folded or twisted bladder can cause inaccurate measurements.
•
Do not touch or apply external pressure against the cuff and air tubing during NIBP measurement.
This may cause inaccurate blood pressure values.
13.6.2 Preparing for NIBP Measurement
1. Verify that the patient category is correct. Change it if necessary.
2. Plug the air tubing into the equipment’s NIBP connector.
3. Select a correct sized 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 upper arm’s length. The
inflatable part of the cuff should be long enough to encircle at least 50% to 80% of the limb.
4. Apply the cuff to an upper arm or thigh of the patient and make sure the Φ marking on the cuff matches
the artery location. Do not wrap the cuff too tightly around the limb. It may cause discoloration, and
ischemia of the extremities. Make sure that the cuff edge falls within the marked range. If it does not, use a
cuff that fits better.
5. Connect the cuff to the air tubing and make sure that the air tubing is not compressed or twisted. Air must
pass unrestricted through the tubing.
6. Switch the Mode Select knob to Monitor.
13.6.3 Starting and Stopping NIBP Measurements
You can start and stop NIBP measurements by pressing the NIBP button on the front panel.
13.6.4 Correcting the Measurement
The cuffed limb should be at the same level as the patient’s heart. If not, correct the measurement by:
■ Add 0.75 mmHg (0.10 kPa) for each centimeter higher, or
■ Deduct 0.75 mmHg (0.10 kPa) for each centimeter lower.
13.6.5 Starting Auto NIBP Measurements
1. Select the NIBP parameter area to enter the [ NIBP Setup ] menu.
2. Select [ Interval ] and then select a desired time interval except [ Manual ]. Selecting [ Manual ] switches to
manual mode.
3. Press the NIBP button on the front panel. The equipment will then automatically repeat NIBP
measurements at the set time interval.
