Patient Preparation for NIBP Monitoring
The Patient Type should be selected, as this setting determines the inflation pressures of the
NIBP cuff, reading times and appropriate alarm limit range.
When positioning the patient, routine NIBP measurements (including for the condition
hypertension) require the patient to remain silent, still and relaxed, with legs uncrossed and arms
supported. Note that during MRI procedures, patients are typically laying down with their legs
uncrossed and arms supported as needed for the MRI scan, and a 5‐minute waiting period is also
recommended before starting readings. Ensure that the cuff is at the level of the right atrium of
In some cases, a patient may exhibit a low pulse amplitude due to any of the following
conditions. The list provides only some examples of potential causes of low pulse amplitudes that
can make NIBP difficult to measure in a convenient and timely manner:

Substitution of components or accessories different from those supplied or recommended
can result in measurement errors.
NIBP accuracy has not been verified in the presence of some common arrhythmias such as
atrial or ventricular premature beats or atrial fibrillation.
The NIBP cuff inflation rate may increase and the initial pressure may increase up to
180 mmHg when changing the patient type.
Patient Category: Select the correct patient category setting for your patient. Do not
apply the higher adult inflation, overpressure limits and measurement duration to
neonatal patients as this may result in inaccurate readings or patient injury.
