Setting Alarm Limits
Adjust Limits with STAT SET
When you want to quickly set all alarm limits, the Propaq Encore can calculate new alarm
limits using the patient’s current values. Press the
STAT SET button in the Alarms Menu (SETUP,
ALARMS, STAT SET). The Propaq Encore activates all alarms and calculates the limits for all
monitored vital signs, except apnea delay. The monitor performs a mathematical function
(addition, subtraction, or multiplication) on the current value of the vital signs to arrive at the
new limits. The formulas for these calculations are shown in the table.

a.New alarm limits calculated by STAT SET cannot be outside the allowable alarm limit range. If a new limit
is calculated to be above or below the allowable alarm limit range, it defaults to the maximum or minimum
alarm limit allowed for that vital sign.
