Sensor Check, Sensor Calibration/Storage and Membrane Change
Note: After switching on the SDM or after a membrane
change (p. 17), it is recommended to store the sensor
in the Docking Station at least for the duration indicated
by the yellow information message ‘Recommended Sensor
Stabilization [min]:’ on the ‘Ready for use’ screen and on the
‘Calibration’ screen.
Note: To maintain monitor readiness in-between monitoring,
always keep the monitor switched on and always store the
sensor in the Docking Station.
Good to know!
SMART CALMEM is a feature of SenTec TC Sensors permit-
ting disconnection of the sensor from the SDM for up to
30 minutes without losing the calibration status. Thus,
monitoring can temporarily be interrupted without the need
to remove the sensor from the patient, e.g. to untangle
cables, to turn or move the patient, or if the patient needs
to go to the restroom. Furthermore, SMART CALMEM
reduces the number of required calibrations and, hence, the
consumption of calibration gas.
Changing the Sensor Membrane
The membrane of a SenTec TC Sensor must be changed if the
‘Membrane Change Interval’ has elapsed. In this case, the SDM
displays the message ‘Change sensor membrane’, triggers a
low priority alarm, marks PCO
2
/PO
2
as invalid and activates
the menu ‘Membrane Change’ - provided the sensor is in the
Docking Station.
Good to know!
The ‘Membrane Change Interval’ is set to 28 days by
default. Depending on the specific requirements of various
clinical settings, the interval can be customized ranging from
1 to 42 days.
CAUTION: Without being requested by the SDM, the
sensor membrane must additionally be changed if any of the
conditions described in the section ‘Checking a SenTec TC
Sensor’ (p. 15) apply.
CAUTION: Use Membrane Changers with a green center
dot only for V-Sign™ Sensors. Membrane Changers with a
blue center dot can be used for all SenTec TC Sensors.
CAUTION: The Contact Gel is not needed in any of the
membrane change steps. The Contact Gel is only used for
sensor application.
