22 Vital Signs Monitor
Setting the Programmable Alarms
The Welch Allyn Vital Signs Monitor has the ability to generate a visual and audible alarm when cer-
tain patient conditions are detected by the monitor. The following chart outliens the conditions,
ranges, programming intervals and default values for the alarm function.
NOTE: Temperature default alarms are 108°F, 42.2°C (high) and 84.0°F, 28.9°C (low). The
temperature alarms are not programmable, they indicate that the patient's
temperature has exceeded the functional range of the thermometer.
*The unit will default to these factory settings only until the operator selects a different alarm limit.
When a new alarm limit is selected, the Monitor will retain this new limit setting in memory, even if
the Monitor is turned off.
Alarm limits may be reviewed or changed by using the SELECT ALARM and SET (arrow up and
arrow down) buttons, and viewing the CYCLE display and the display of the parameters being
changed.
Blood Pressure - High Systolic Limit
Press the SELECT ALARM button until the SYSTOLIC display is illuminated, and the CYCLE display
shows "HI." This indicates the high systolic alarm setting.
The systolic display will show the current alarm limit for high systolic blood pressure in mmHg or
three dashes ("---") if the alarm is turned off. Pressing the SET (arrow up and arrow down) buttons
will cycle through the options in 5 mmHg intervals. The operator may choose the high systolic
blood pressure limit within the range of 245mmHg through the current low systolic alarm limit. The
alarm may be turned off by choosing "---."
When the desired alarm limit is displayed, pressing SELECT ALARM again saves the displayed
alarm limit and changes the alarm parameter. Alternatively, pressing no buttons for approximately
10 seconds will cause the displayed value to be set as the alarm limit, and the Monitor will automat-
ically revert to the current operating mode.
Warning: It is the operator’s responsibility to set alarm limits as appropriate for each
individual patient.
