Non-invasive blood pressure (NIBP)
Patient preparation for non-invasive blood pressure monitoring
The following tips provide optimal non-invasive
blood pressure monitoring results, but must never
replace hospital-approved practices or
manufacturer’s recommendations.
Accurate non-invasive blood pressure
measurements depend on the correct size and type
of the blood pressure cuff in relation to the arm
circumference of the patient. The wrong sized cuffs,
or cuffs outside the range or size manufactured by
Dräger, can cause inaccurate measurements. Use
only Dräger approved cuffs and make sure that the
correct size is used for each patient.
Applying the blood pressure cuff
Weak or irregular pulses, patient movement,
tremors, or respiratory artifacts can affect the
accuracy of non-invasive blood pressure
measurements and even cause them to fail. Before
applying the cuff, read the non-invasive blood
pressure precautions.
We recommend that you do not apply the cuff on a
limb that is already used for other measurements.
Make sure that other patient connections do not
interfere with each other.

Correct patient positioning
For a patient with hypertension who is not in a lying
position, perform the resting blood pressure
measurement as follows:
– Place the patient in a comfortable seated
position.
– Make sure the legs are not crossed.
– Make sure the feet are flat on the floor.
– Make sure the patient is leaned back and arms
are at rest.
– Apply the center of the cuff at the level of the
right atrium.
– The patient should be relaxed, if possible, and
should not talk during measurement.
– Wait for 5 minutes, if possible, before
performing the first measurement.

NOTE
The accuracy of the blood pressure measurement
can be affected by the following conditions:
– The measuring site, the lying position, patient
movement, and the physiological condition of
the patient.
– Cuffs that are stored or used outside of the
specified environmental conditions. For
acceptable conditions, refer to the
