In Vivo Adjustment™
The In Vivo Adjustment feature lets clinicians manually adjust one or more clinical
parameters to match that of a corresponding laboratory reference for continuous trending. To
remind clinicians that the feature is active, an offset value displays alongside the adjusted
parameter value.
In Vivo Adjustment for a parameter can be turned on by accessing the In Vivo screen in the
settings menu of that parameter. After enabling the feature, set an offset value. Once the
feature is enabled, a positive or a negative offset value appears on the main display
underneath the parameter value.
The In Vivo offset is set to zero for any of the following:
• Cable or sensor is disconnected from instrument.
• Sensor goes off patient causing a sensor initialization to occur.
• Eight hours has elapsed since the In Vivo value was activated.
• Restoration of factory defaults.
• The user turns off In Vivo.
Offset Value
When In Vivo Adjustment is activated for a specific parameter, the offset value appears
beneath that specific parameter on the secondary display connected to the device. A positive
value means that the displayed parameter value has been increased (according to a
laboratory reference value as entered by a clinician) and a negative value means the
displayed parameter value has been decreased (according to a laboratory reference value as
entered by a clinician).
In Vivo Adjustment can be set to On or Off. The factory default setting is Off. If set to On, the
parameter value is adjusted and an offset value appears. The offset value is set by the user.
Note: When In Vivo Adjustment is enabled for a specific parameter, the alarm states for that
parameter are based on the offset values as opposed to the measured values. Check the alarm
limits each time In Vivo Adjustment is enabled.
