No Data Indications
Under certain conditions, no waveforms and one or more vital sign numerics may display three
dashes (‐ ‐‐ ), which indicates that no data is available for the parameter(s).
Depending upon the cause of this missing data, an alarm condition may be generated.

If a module or another measurement device was just turned on or applied to the patient,
allow a few seconds for communication to be established, or for any required warm‐up
period to occur.
The first reading has not yet been taken or the parameter is in a start‐up condition (for
example, the AGENT or CO2 monitoring hardware may be warming up).
The measurement values are distorted or the signal is inadequate (for example, the
concentration of gases may be below the minimum volume percentage detectable).
Suspend mode was just exited.
Parameter data was present but can no longer be produced (for example, an attachment
applied to a patient may have become disconnected).
The hardware associated with a parameter has experienced a problem or failure that
prevents proper operation.
