Maternal Non-Invasive Blood Pressure Monitoring: NIBP Monitoring
The systolic and diastolic pressures are each indicated with two or three digits and
separated by a slash (/). The mean arterial pressure is indicated with two or three digits
and enclosed in parentheses. All pressure values are displayed in mmHg or kPa.
Systolic, diastolic, MAP, and pulse rate values are printed on the strip chart paper
annotated by an outlined diamond ( )which marks the time of the reading.
Hydrostatic Effect
If patient is standing, sitting, or inclined ensure that cuffed limb is supported to
maintain cuff at level of patient’s heart. If cuff is not at heart level, the difference in
systolic and diastolic values due to hydrostatic effect must be considered. Add 1.80
mmHg (0.24 kPa) to values for every inch (2.54 cm) above heart level. Subtract 1.80
mmHg (0.24 kPa) from values for every inch (2.54 cm) below heart level.
Manual Mode
In manual mode, press the NIBP Start/Stop button to begin a single determination. The
cuff will inflate to the target pressure. If this initial inflation pressure is insufficient,
the unit retries with a higher inflation pressure (+40 mmHg; +5.3 kPa). The
instantaneous cuff pressure is displayed in place of the mean arterial pressure area
and is indicated by the title Cuff.
If you have the 256 Monitor–which does not have the NIBP parameter installed–and
press the
NIBP Start/Stop button, the message NOT INSTALLED appears under the NIBP
label on the monitor’s screen.
Automatic Mode
In auto mode an indefinite series of determinations are made at defined time
intervals. Upon activation, a clock icon ( ) displays in the NIBP area indicating the
time remaining until the next scheduled automatic determination.
NOTE: The first automatic determination begins after the expiration of one
complete interval time period.
Since the first automatic blood pressure reading will not occur until after a complete
interval time, you may wish to take an initial manual reading by pressing the
NIBP
Start/Stop
push button. Automatic determinations inflate to the target pressure if no
previous values are displayed. If previous values are displayed the cuff inflation
target pressure is based on the previous values. If this initial inflation pressure is
insufficient, the unit retries with a higher inflation pressure. The instantaneous cuff
pressure is displayed in place of the mean arterial pressure area and is indicated by
the title Cuff.
WARNING
The NIBP parameter should be set to determine blood pressures
only as frequently as is clinically indicated to ensure adequate
patient monitoring.
