Positioning the NIBP
The NIBP cuff should be positioned as it would be for an auscultatory blood pressure
determination. The current guidelines of the American Heart Association must be followed. Wrap
the NIBP cuff firmly (not snuggly) around the arm or leg of the patient, making sure that the cuff
is at the approximate level of the heart to ensure accuracy of the obtained values.
Connecting the NIBP Cuff
Routinely inspect the NIBP cuff and hose assemblies for proper connection and orientation.
Replace accessories that have cracks, holes, tears, or cuts that could cause leaks in the
system. If such damaged NIBP cuff or hose assemblies are used, prolonged and/or inaccurate
patient readings could result.

Avoid compression, kinking or restriction of the NIBP cuff hose, as the effect of blood
flow interference can result in patient injury caused by continuous cuff pressure.
Do not use the NIBP cuff on a limb with an intravenous infusion or where an arterial
catheter or arterio-venous (A-V) shunt is in place because of temporary interference to
blood flow. This could result in injury to the patient.
Do not place the NIBP cuff over a wound, as this can cause further injury.
Do not place the NIBP cuff on the same or adjacent arm to a mastectomy, or where the
lymph nodes were removed, or if a shunt is on that arm. This can lead to bruising,
inaccurate readings, or negatively impact the drainage of fluids because of temporary
interference to blood flow.
Insert the appropriate interconnect hose connector onto the NIBP
port. Push the hose connector forward and then turn it clockwise.
