Maintenance
To perform the Efficia DFM100 EtCO2 sensor flow rate check and accuracy check, you need:
EtCO
2
Calibration service tool (453564501951)
The Efficia DFM100 EtCO
2
option allows you to use two CO
2
sensor types:
• Mainstream (Capnostat series, requires a Capnostat airway adapter)
• Sidestream (LoFlo series, requires a LoFlo airway adapter)

Sensor and Adapters
NOTE: To connect the adapter to an EtCO
2
Sensor, refer to Efficia DFM100 Defibrillator/Monitor IFU.
The EtCO
2
maintenance procedures consists of:
• Setting Ambient Pressure
•Flow Rate Check, and
• Accuracy Check
You will need the following supplies:
•5% CO
2
gas cylinders
• Gas flow valve providing a flow rate of 2 liters per minute
• Flowmeter (for Flow Rate Check only)
• Modified airway adapter matching the CO
2
sensor to be checked. If no modified adapter is
available, then, depending on your sensor type, you may create one similar to the one shown on
Figure 29 on page 28 or Figure 30 on page 29.
