9.2 Safety
WARNING
•
During NIBP measurement, the inflated cuff applies pressure on the
application site. The clinician determines if NIBP measurement is suitable for
the patient.
•
Be sure to select the correct patient category setting for your patient before
measurement. Incorrect patient category selection may present a safety
hazard.
•
Do not measure NIBP on patients with sickle-cell disease or on the limb
where skin damage has occurred or is expected.
•
Use clinical judgement to determine whether to perform frequent
unattended blood pressure measurements on patients with severe blood
clotting disorders because of the risk of hematoma in the limb fitted with the
cuff.
•
Do not use the NIBP cuff on a limb with an intravenous infusion or arterial
catheter in place. This could cause tissue damage around the catheter when
the infusion is slowed or blocked during cuff inflation.
•
NIBP measurements can be affected by the measurement site, the position of
the patient, patient movement, or the patient's physiologic condition. If the
NIBP measurement seems out of range or inaccurate, determine the patient’s
vital signs by alternative means and then verify that the monitor is working
correctly.
•
Make sure the hose connecting the NIBP cuff and the monitor is not blocked,
twisted, or tangled.
•
Do not apply the cuff on the arm on the side of a mastectomy.
•
Continuous cuff pressure due to connection tubing kinking may cause blood
flow interference resulting injury to the patient.
9.3 Measurement Limitations
The equipment cannot measure blood pressure when the patient's heart rate is below
40 bpm or above 240 bpm, or if the patient is on a heart-lung machine.
The equipment may fail to measure or produce inaccurate blood pressure
measurements under the following conditions:
■
If arterial pressure pulses are hard to detect
■
In the presence of excessive and continuous patient movement such as shivering
or convulsions
■
During certain cardiac arrhythmias
