resume normal deflation sequence.
The monitor continues to use a higher cuff inflation pressure through
subsequent determinations made within 90 minutes AUTO MODE or one
minute MANUAL MODE. If the patient’s systolic pressure falls, the unit will
then lower cuff pressure accordingly.
Under certain circumstances, the monitor may display only MAP and not
display values for systolic and diastolic pressures. If the patient is in
shock, the systolic/diastolic waveform has very low amplitude
fluctuations as shown in Figure 4-3, Low Amplitude Waveform Diagram.
Because of the relatively small difference between systolic and diastolic
pressure in a shock situation, only MAP can be accurately determined and
only MAP will be displayed. If this condition occurs while in auto mode, the
monitor will attempt one or more additional determinations after a 15 second
delay.

Neonatal or Adult/Pediatric Monitoring
The monitor automatically switches between neonatal and adult/pediatric
monitoring at the beginning of a determination when the appropriate hose
is used. No operator intervention is required. Default adult/pediatric or
neonatal alarm limits are switched
on/y if limits have not been set or viewed.
However, if alarm limits have been viewed or set, the monitor retains those
limits.
Systolic Search
In any operating mode, should a patient’s systolic pressure exceed the
monitor’s pump-on pressure, the unit will
