Measuring and Monitoring etCO
2
•
Obtain a new airway adapter and check that the
windows are intact and clean.
•
Attach the airway adapter to the sensor (the
triangles on the airway adapter and on the
sensor must be in alignment - Figure 10-3).
•
Connect the airway adapter to the respirator
system (connector
c
towards the patient, con-
nector
d
towards the respirator - Figure 10-3).
•
Ensure that the sensor is on top and that the
windows of the airway adapter are in a vertical
position. Although the "No-fog-membrane"
prevents moisture condensation on the window,
liquid secretions could soil the window.
•
Connect the sensor to the defibrillator (yellow
connector, right).
The CO
2
measurement begins as soon as the sensor
is connected. During the short self-test, the
parameter window is blue. As soon as the sensor
supplies a valid reading, the color changes to
green. Check that the indicator on the CO
2
adapter
cable lights green; if a problem is detected, the
indicator flashes red (apnea or system failure).
At the factory, only a low etCO
2
limit of 20 mmHg
is adjusted, no high limit. When the parameter
reading drops below this value, the defibrillator
sounds an alarm and the window changes from
green to red.
