1.3.5 ALARMS
The Accutorr Plus provides “HI” and “LO” alarm limit settings for systolic, diastolic,
MAP, pulse rate and SpO2. An alarm violation occurs when one or more patient
parameters equals or falls outside the limits that have been specified.
1.3.5.1 Setting Alarm Limits
The Factory Default for all parameter alarms, except Low SpO2, is OFF. The Low SpO2
factory default is 86. The User Configuration mode can be used to set custom defaults.
See section 1.3.15, User Configuration for details. The factory and custom defaults for
alarms can be changed as required to accommodate the needs of individual patients. The
SET ALARMS key (29) and the Patient Info. Up and Down Arrow keys (27 & 28) are
used to set alarm values.
1. Press the SET ALARMS key (29) (1 beep) to enter into the alarm set mode.
The first time this key is pressed, all NIBP displays blank except for the systolic
display which shows the current high systolic alarm value. The word HI is displayed
in the Interval/Elap. Time/Temp display (33). When the unit has been configured to
display graphics, the symbol is displayed. When the graphic is displayed, the
top lines blink. This indicates the high alarm is selected.
The second time the SET ALARMS key (29) is pressed the Systolic LO parameter is
selected. The word LO is displayed in the Interval/Elap. Time/Temp display (33).
When the unit has been configured to display graphics, the symbol is
displayed. When the graphic is displayed, the bottom lines blink. This indicates the
low alarm is selected.
Each time the SET ALARMS key (29) is pressed a new parameter is selected for alarm
setting (all other displays blank). The order they are available is: Systolic HI, Systolic
LO, Diastolic HI, Diastolic LO, MAP HI, MAP LO, Pulse Rate HI, and Pulse Rate
LO, SpO2 HI and SpO2 LO. When all of the available parameters have been selected,
the next press of the SET ALARMS key returns the Accutorr Plus to normal
operation.
2. To change an alarm limit setting, use the Patient Info. Up & Down Arrow keys (27 &
28). The Up arrow increments the alarm limit setting. The Down arrow decrements
the alarm limit setting.
To cancel all of the changed alarm values while still in progress of changing, press the
DEFAULTS key (14) (1 beep tone).
If the SET ALARMS or Arrow keys have not been pressed for 15 seconds, the
Accutorr Plus returns to normal operation and saves any alarm limit changes.
NOTE: If the patient size is changed, the alarm settings will change to the default
settings for the new patient size.
