4.7 NIBP monitoring
The non-invasive blood pressure is measured by the oscillometric method.
The module performs single measurements and automatic measurements at
selectable intervals.
The automatic measurements are suitable also for pregnant or pre-eclamptic patient.
Make sure that the cuff is on a level with the heart during blood pressure
measurements. If this is not ensured, the hydrostatic pressure of the liquid column in
the blood vessels will lead to incorrect results. When the patient is sitting, standing or
supine during measurements, the cuff is automatically at the correct level.
Factory default cuff pressure adult = 180 mmHg, children = 150 mmHg,
neonates = 50 mmHg
The initial cuff pressure is configurable. The maximum cuff pressure configuration in
neonatal mode is 150 mmHg.
To prevent extensive pressure on the extremity, it is very important to choose
the correct cuff size and to check the setting patient type adult, children or
neonates.
On
neonatal
patient, it is imperative to selected first the neonatal MODE. A
erroneous MODE selection will lead to higher pressure which can cause
haematoma or an osseous deformation.
When
neonatal
MODE is selected the maximal pressure is lowered and the time
measure is shorter. An erroneous MODE selection on neonatal patients would
engender inadequate pressure and time measure.
In case of long-term monitoring or automatic operation, the connected body
areas of the patient and the extremity to which the cuff is attached must be
checked regularly for signs of ischaemia, purpura and/or neuropathy, especially
in patients with decreased pain sensitivity (due to medication), or with older
patients with decreased blood circulation of the extremities.
The cuff must not be attached to a limb that is already used for interventions
such as:
– infusions or
– SpO

measurement (loss of data can occur during cuff inflation) or
– if an arterio-venous shunt is present.
To prevent extensive pressure on the extremity and incorrect measurement
results, make sure that the tube is not kinked or compressed.
To achieve correct arterial pressure measurement, the cuff must always be
installed on the level of the right atrium.
In order to reduce interferences and the danger of burns for the patient, keep the
cuff and hose as far away as possible from the operated area and the
electrosurgical cables. Make sure that the electrosurgical return conductor
(neutral) is well attached to the patient and that a good contact is guaranteed.
In some patients petechiae, haemorrhages or subcutaneous haematomas may
occur. All patients must be told when putting on the cuff that if they experience
pain during the recording they should switch off the equipment and inform the
doctor.
When an automated measurement interval is defined, bruising or decreased
blood circulation can occur in the arm. Only carry out recordings with automated
measurement intervals under constant medical supervision.
It must be certain that, according to the health of the patient, the use of the
device will not damage blood circulation in the arm.
