confirm it is well fixed.
2. Connect the sampling cannula or the sampling line to the water trap.
3. Set Work Mode to Measure.
4. For intubated patients, an airway adapter is required. For non-intubated patients, place the
nasal cannula or the sampling mask onto the patient.
CAUTION
1 The water trap collects water drops condensed in the sampling line and therefore
prevents them from entering the module. If the water trap is nearly filled, you should
replace it to avoid blocking the airway.
2 Based on a sample gas temperature of 37 °C, a room temperature of 23 °C and
sample relative humidity of 100%, the water trap will be filled after approximately 90
hours with the flowrate of 100 ml/min and approximately 130 hours with the flowrate
of 70 ml/min. In clinical practice, the water trap can be used for a longer time before it
is filled. It is recommended to replace the water trap once every month.
3 When replacing the water trap or suspecting the measurement value, please check if
the O-rings of the water trap holder are normal and well installed. If the O-rings get
damaged or loose, contact EDAN’s service staff.
4 To prevent the module from abnormal work, please ensure the water trap detection
button is not mistakenly touched.
5 Please replace and discard the water trap when blocking. Don’t reuse it, otherwise
the reading is not accurate and even the device may be damaged.
NOTE:
1 Disconnect the water trap from the holder or set Work Mode to Standby when the
module is not in use.
2 To avoid patient cross infection, do not connect the exhaust tube to the ventilator
circuit. If the sampled gas is returned to the breathing system, always use the
bacterial filter of the sample gas return kit.
For the Respironics Sidestream CO
2
Module:
1. Plug the sensor cable into the CO
2
input connector on the sidestream CO
2
module. Allow the
sensor two minutes for warm-up.
2. Connect the cannula, airway adapter, or sample line as required to the sensor. It will click
into place when seated correctly.
3. To zero the sensor, please refer to zeroing the sensor.
4. For intubated patients, an airway adapter is required;
