Airway gas
17-7
Patient connections
1. Make sure that the water trap container is empty and properly attached.
2. Connect the gas sampling line to the sampling line connector on the water trap.
3. If CARESCAPE Respiratory Module or Airway Gas Option is used with N
2
O or volatile
agents, connect the sample gas outlet to gas scavenging.
4. Turn on the monitor. The monitor performs a self-check. Make sure the related gas
measurement is
ON . Automatic agent identification is activated in those modules that
have this feature.
5. Wait until the message ‘Calibrating gas sensor’ disappears before connecting the
sampling line to the airway adapter or the airway adapter to the ventilator circuit.
6. Position the adapter with the sampling port upwards. This prevents any condensed water
from entering the sampling line.
7. Check that the airway adapter connections are tight and that the adapter is operating
properly.
8. If E-miniC is used with O
2
and/or N
2
O contents higher than 40%, make sure that FiO
2
Level
and N
2
O Level are set.
NOTE: Check that the sample line is connected to the water trap before connecting the
module to the monitor or turning on the monitor.
NOTE: To minimize the amount of dust drawn into the gas sampling system, always
keep the water trap connected to the module. When gas measurement is not in use,
you can disconnect the module from the monitor to eliminate the operating sound of
the gas pump.
