3. Connect the other end of the sampling line to the patient.
◆ For intubated patients requiring an airway adapter, install the airway adapter between the patient
circuit and the ventilator Y-piece.
◆ For non-intubated patients, place the nasal cannula onto the patient.
4. Connect the gas outlet to the scavenging system using an exhaust tube.
After the CO
2
module is connected, it enters measure mode by default and the equipment displays “CO2
Startup”. C O
2
can be measured after the start-up is complete.
• Connect the gas outlet to the scavenging system when measuring CO
2
.
• If not necessary, do not disconnect the CO
2
adapter from the equipment after the first installation.
This reduces the risk of the CO
2
adapter becoming lost or damaged.
• When sample gas of 37 °C, sample flowrate of 50 ml/min, room temperature of 23 °C, 100% RH, the
sampling line with a general type should be replaced once at most every 8 hours, and the sampling
line with a humidified type should be replaced once at most every 72 hours.
14.5.2 Zeroing the CO
2
Sensor
The zero calibration eliminates the effect of baseline drift during CO
2
measurement exerted on the readings and
therefore maintains the accuracy of the CO
2
measurements.
A zero calibration is carried out automatically when necessary. You can also start a manual zero calibration if
necessary.
