4. To select the currently displayed interval, press any button other than , or .
Ten seconds after you select an interval, and assuming that safe venous return
pressure (SVRP) has been maintained for at least 30 seconds, the monitor starts the
first automatic NIBP cycle and the following occurs:
• The cuff inflates to the default pressure level.
• The SYS window dynamically displays the current cuff pressure.
• If MAP is enabled, the MAP measurement value alternates with the time display
in the message window.
When the NIBP cycle ends, a tone sounds and the monitor displays the measurement
results, including pulse rate in the window. (If the SpO
2
sensor is attached to
the patient, the pulse rate is derived from the SpO
2
sensor.)
The measurement display persists until one of the following occurs:
• the next cycle begins, if the monitor is still in automatic NIBP mode
• two minutes pass
• is pressed again
Note
If a MAP alarm occurs, the MAP is displayed steadily in the message window.
Note
If the first cycle does not produce a measurement, the monitor retries the
measurement using a target pressure calculated from the results of the previous
cycle.
