Maternal Non-Invasive Blood Pressure Monitoring: Blood Pressure Safety Precautions
Blood Pressure Safety Precautions
NOTES
‹
This safety information applies to the non-invasive blood pressure (NIBP)
of the monitor.
‹ A patient’s vital signs may vary dramatically during the use of
cardiovascular agents such as those that raise or lower blood pressure or
those that increase or decrease heart rate.
CAUTIONS
Accuracy of NIBP measurement depends on using a cuff of the
proper size. It is essential to measure the circumference of the
limb and choose the proper cuff size.
ACCURACY—As with any non-invasive oscillometric blood
pressure monitor, there are clinical conditions which can affect the
accuracy of the measurements obtained. For example, do not use
the monitor’s NIBP feature on a patient experiencing convulsions
or who is attached to a heart/lung machine. In addition, disregard
or stop automatic blood pressure determinations that coincide with
maternal contractions. Finally, be aware that the accuracy of
measurements can be affected if readings coincide with maternal
uterine contractions. Refer to “Smart BP Feature” on page 8-13.
CALIBRATION—Do not operate the monitor unless it has been
properly calibrated. Inaccurate blood pressure readings may
result. Refer to Chapter 15, “Maintenance” for details.
DISPLAY INTERVAL—The time period, in minutes, that a blood
pressure reading remains displayed before being automatically
erased, is selectable via the password-protected
Install Options
Screen 2.
The option can also be set to continuously display the
reading until replaced by a new reading. The display of “old”
pressure values may cause confusion. If a patient’s condition
changes during the time interval between determinations, the
monitor will not detect the change or indicate an alarm condition.
Blood pressure and pulse can fluctuate greatly between
measurements; the monitor does not alert the user (through audio
or visual means) to changes in NIBP or NIBP-derived pulse rate
occurring between measurement cycles.
EXTERNAL PRESSURE—Do not apply external pressure
against the cuff while monitoring. Doing so may cause inaccurate
blood pressure values.
