10.2 Setting Alarm Limits
CAUTION: Do not set the alarm limit to extreme values that can cause the alarm to
become useless.
During patient monitoring, an alarm occurs when a measurement falls outside the
programmed alarm limit. Alarms can be set or turned off for the following vital signs:
• Systolic high and Systolic low alarm limits
• Diastolic high and Diastolic low alarm limits
• MAP high and MAP low alarm limits
• Pulse rate high and Pulse rate low alarm limits
• SpO

The range of high and low alarm limits for each vital sign is shown here:
