To prepare the CO
2
 module for measurement, follow this procedure:
1. Select the appropriate gas sample line and watertrap according to the patient category.
2. Connect the DRYLINE II watertrap to the CO
2
 module, and connect the gas sample line to the watertrap.
3. Connect the other end of the gas sample line to the patient.
◆ For intubated patients requiring an airway adapter, install the airway adapter between the patient 
circuit and the ventilator Y-piece.
