Maternal Non-Invasive Blood Pressure Monitoring: Warnings
CAUTIONS
PULSE RATE COMPARISONS—The pulse rate measured by the
monitor’s NIBP circuitry may differ from the heart rate measured
by the monitor’s MECG circuitry or another maternal ECG
monitor because the monitor’s blood pressure module measures
peripheral pulses, not electrical signals or contractions of the
heart. Occasionally, the electrical signals at the heart do not
produce a peripheral pulse. Similarly, if a patient’s beat-to-beat
pulse amplitude varies significantly, blood pressure and pulse rate
readings can be erratic and an alternate measuring method should
be used for confirmation.
Warnings
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.
Use care when placing the cuff on an extremity used to monitor
other patient parameters.
The monitor is intended only for use in the non-invasive
monitoring of maternal blood pressure (NIBP). This monitor is
not intended for use in neonatal or pediatric blood pressure
monitoring.
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.
