Vital Sign Value State
A vital sign value is considered missing (as indicated by three dashes, ‐ ‐ ‐) when the vital sign has 
produced a value since the monitor was turned on, but can no longer produce a value. Examples 
of the values that could become missing during normal use, include:
When a value becomes missing due to an INOP, an INOP alarm will be present. And, a patient 
alarm—due to the missing value—will be present as well. Therefore, the system can have an 
INOP alarm, and a patient alarm, active at the same time and from the same cause. 
WARNING
If, during use, an alarm condition listed below results in a loss of patient monitoring
capability, employ an alternate means as needed to prevent a lapse in patient monitoring;
otherwise, treatment of the patient could be delayed.

Patient and INOP Alarms

The measurement labels and abbreviations for pressure, temperature, SpO2, CO2 and anesthetic 
agent alarms are explained in the individual chapters. The following table contains a listing of 
patient alarms arranged by vital sign or parameter. The parameter must be on for the respective 
alarm detections to be enabled; see page 3‐18.
Note
In the case of missing data (- - -), an alarm will occur only if a valid numeric was previously displayed but can
no longer be produced; see page 2-20 for details.
