OPERATING MODES
Continued
A determination in progress may be canceled at any time by
pressing the CANCEL switch. This action deflates the cuff
and begins a new wait cycle (as displayed in the CYCLE
MINUTES display). Any operator set alarm limits are
unaltered. Alarm indicators can be canceled (after a
determination has caused an alarm condition) by pressing
the CANCEL switch. This action silences and extinguishes
all patient alarm indicators, begins a new wait cycle (as
displayed in the CYCLE MINUTES display), and leaves
operator set alarm limits unaltered.
Neonatal or Adult/Pediatric Monitoring
The monitor automatically switches between neonatal and
adult/pediatric monitoring by detecting cuff size at the
beginning of a determination. No operator intervention is
required. Default adult/pediatric or neonatal alarm limits
are switched
only 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-up pressure, the unit will
1.
begin normal deflation sequence,
2.
detect the absence of a systolic value,
3.
stop deflation,
4.
reinflate to a higher (than initial) pump-up pressure
(250 mmHg, maximum), and
5.
resume normal deflation sequence.
The monitor continues to use a higher pump-up pressure
through subsequent determinations made within 90
minutes AUTO MODE or on minute MANUAL MODE. If the
patient's systolic pressure falls, the unit will then lower
pump-up pressure accordingly.

SYSTOLIC AND
DIASTOLIC
P R E S S U R E S
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.
