3. Plug in the CO
2
sensor cable to the Mainstream CO
2
connector on the Propaq left side
panel.
4. Set up the CO
2
channel and alarms. Follow the steps described on page 81.
How to Set Up the CO
2
Channel and Alarm Limits
After you connect the Mainstream CO
2
sensor or Sidestream CO
2
watertrap, follow these
steps to set up the CO
2
channel and alarm limits.
1. Press
SpO2/CO2, CO2
to display the first CO
2
Menu.
2. Press
RANGE
until you see the desired waveform scale range on the Propaq screen. The
range choices are shown below.
Warning When attaching the airway adapter, position the adapter so the
sensor is on top to avoid fluid collection in the sensor airway slot. Any
concentration of fluids here can cause inaccurate CO
2
readings.
Always check to make sure there are no leaks in the breathing circuit. Check
all of the connections.
Warning When disconnecting the CO
2
sensor from the tracheal or
endotracheal tube, check the sensor to determine how hot it is. If it is too hot
for patient comfort, do not allow it to come into contact with the patient.
When disconnecting the airway adapter from the ventilator circuit, always
detach the
CO
2
sensor from the airway adapter before removing the airway
adapter from the ventilator circuit.
After you connect a Mainstream CO
2
sensor or Sidestream CO
2
watertrap, the
Propaq displays the waveform briefly without a value range. It displays WARM
UP (for Mainstream) or START UP (for Sidestream) in the
CO
2
numerics
window. After about 20 seconds, the Propaq displays the CO
2
measurement
and waveform range.
