Airway gas17-7Patient connections1. 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 2O or volatileagents, connect the sample gas outlet to gas scavenging.4. Turn on the monitor. The monitor performs a self-check. Make sure the related gasmeasurement is ON. Automatic agent identification is activated in those modules thathave this feature.5. Wait until the message ‘Calibrating gas sensor’ disappears before connecting thesampling 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 waterfrom entering the sampling line.7. Check that the airway adapter connections are tight and that the adapter is operatingproperly.8. If E-miniC is used with O2 and/or N2 O contents higher than 40%, make sure that FiO 2 Leveland N2 O Level are set.NOTE: Check that the sample line is connected to the water trap before connecting themodule to the monitor or turning on the monitor.NOTE: To minimize the amount of dust drawn into the gas sampling system, alwayskeep 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 ofthe gas pump.Alternative airway gases patient connections with gas modulesTracheostomy(1) Tracheostomy tube with 15 mm connector(2) Heat and Moisture Exchanger (HME)(3) Airway adapter(4) Sample line1243
