Problem
Possible Cause(s)
Recommended corrective action(s)
P0100
After sensor
application or
a ‘TC artifact’
PCO2 values
increase
slowly or PO2
values
decrease
slowly or do
not stabilize
within 10
minutes
Sensor loosely
attached to patient
(air between sensor
and skin; no
contact liquid)
Verify that the sensor is securely attached
and ensure that air gaps are eliminated
between the skin and the sensor. If needed,
reapply the sensor (on same or an alternate
site). For instructions refer to the Quick
Reference Guide for the SDMS or the
Instruction Manual for the SDMS .
Consider to use the Staysite™ Adhesive
(model SA-MAR) to complementary attach
Multi-Site Attachment Rings if more secure
sensor attachment is required, e.g. in high
humidity environments, for patients who
perspire profusely and/or in challenging
patient motion conditions.
Note: Typically PaCO2 is > 25 mmHg in
humans and PCO2 of ambient air < 0.5
mmHg. If the contact between the sensor
and skin is not hermetically sealed PCO2
readings, consequently, may increase slowly
after sensor application or a ‘TC artifact’ and
be too low thereafter.
Note: Typically PaO2 is < 100 mmHg in
humans and PO2 of ambient air > 130
mmHg. If the contact between the sensor
and skin is not hermetically sealed PO2
readings, consequently, may decrease slowly
after sensor application or a ‘TC artifact’ and
be too high thereafter.
Note: Also refer to Status Messages ‘Check
sensor application’, ‘PCO2 stabilizing’, ‘PO2
stabilizing’, or ‘PCO2/ PO2 stabilizing’ (refer to
the Technical Manual for the SDM ).
Sensor applied to a
measurement site
that is inadequate /
not recommended
for PCO2/ PO2
monitoring
Apply sensor to a recommended
measurement site with an appropriate Sensor
Attachment Accessory. For instructions refer
to the Quick Reference Guide for the SDMS
or the Instruction Manual for the SDMS .
Excessive use of
contact liquid
Remove sensor. Clean sensor and
measurement site with an alcohol pad.
Reapply the sensor using only one drop of
contact liquid.
