1.3.7.2. NIBP
Use only NIBP accessories approved for MRI use (See MRI Accessory list in Section 9).
When using the NIBP portion of this instrument to measure blood pressure, remember that the
patient’s blood pressure readings are not continuous, but are updated each time a blood
pressure measurement is taken. Set a shorter interval for more frequent updating of the
patient’s blood pressure.
Do not attach the NIBP cuff to a limb being used for infusion, therapy or an arterio-venous (A-V)
shunt. Cuff inflation can block infusions, therapy or shunt bypass, possibly causing harm to the
patient.
Frequent NIBP measurements can cause pooling of the blood in the limb (hemostasis), and
peripheral tissue/nerve damage. Allow sufficient time for blood recirculation to prevent pooling
of the blood in the limb.
Arrhythmic and/or erratic heart beats (or severe motion artifact, such as tremors or convulsions)
can result in inaccurate readings and/or prolonged measurements. If questionable readings are
obtained, re-check patient’s vital signs by alternate means before administering medication.
To prevent possible nerve damage to the limb, apply the NIBP cuff as recommended by current
American Heart Association (AHA) guidelines for blood pressure monitoring.
To ensure accurate and reliable measurements, use only recommended NIBP cuffs/hoses. For
best accuracy, use the appropriate cuff size for each patient as recommended by the current
American Heart Association (AHA) guidelines for blood pressure monitoring.
Always tighten the NIBP cuff air hose connections snugly into place for proper operation.
Avoid NIBP measurements on any limb with swelling (e.g. from lymphedema). Patient harm
and/or inaccurate measurements could result.
Routinely inspect the NIBP cuff and hose assemblies for proper attachment and orientation.
Replace any damaged cuff and/or hose assemblies with cracks, holes, tears, cuts, etc. that
could cause leaks in the system. If cuff and/or hose assemblies with damage which could result
in leaks are used, prolonged and/or inaccurate patient readings could result.
To prevent skin abrasion, apply and remove NIBP cuff carefully. Keep Velcro® (hook and latch)
retention areas away from the skin.
Always use recommended NIBP cuffs and hoses. Avoid compression or restriction of NIBP
hose.
