NIBP: Indications and Contraindications
WARNINGS
The NIBP parameter will not measure blood pressure
effectively on patients who are experiencing seizures or
tremors.
Arrhythmias will increase the time required by the NIBP
parameter to determine a blood pressure and may extend the
time beyond the capabilities of the parameter (120 seconds for
adult/pediatric and 85 seconds for neonate).
The Dash 2500 Patient Monitor displays the results of the last
blood pressure determination for 120 minutes or until another
determination is completed. If a patient's condition changes
between one determination and the next, the NIBP parameter
may not detect the change or indicate an alarm condition.
Devices that exert pressure on tissue have been associated
with purpura, skin avulsion, compartmental syndrome,
ischemia, and/or neuropathy. To minimize these potential
problems, especially when monitoring at frequent intervals or
over extended periods of time, make sure the cuff is applied
appropriately and examine the cuff site and the limb distal to
the cuff regularly for signs of impeded blood flow.
Do not apply external pressure against cuff while monitoring.
Doing so may cause inaccurate blood pressure values.
Use care when placing cuff on extremity used to monitor other
patient parameters.
Use only accessories recommended by GE Medical Systems
Information Technologies. Failure to use recommended
accessories may result in inaccurate readings.
Blood pressure cuffs should be removed from the patient when
the Monitor is powered off. If the extremity remains cuffed
under these conditions or if the interval between blood
pressure determinations is prolonged, the patient's limb should
be observed frequently and the cuff placement site should be
rotated as needed.
In patients with irregular rhythm, wait 3 minutes after ECG has
been connected and ECG heart rate is present on the monitor
screen before performing an NIBP determination.
