z For Sidestream
a. Connect the sidestream sampling line to the inlet port located on the metal
container on the front of the CO
2
module. You will hear a click when properly
inserted.
b. A “CO
2
- Sensor Warming-up” message displays for up to 2 minutes,
depending on the temperature of the environment, the temperature of the
module, and the temperature of the sensor.
c. Breathe through the CO
2
airway adapter for five slow breaths. Verify that the
displayed waveform rises and falls accordingly.
d. Connect a gas cylinder containing 10% CO
2
to a flow meter and then to the
CO
2
airway adapter.
e. Turn the gas On and verify that the flow through the airway adapter is 200 to
300 ml/min
f. Allow the reading to stabilize for 15 seconds.
g. Verify that the monitor displays 76 ± 2 mmHg (10 ± 0.2 %) in CO
2
numerical
area.
4. Test #2: Flow Rate Accuracy
a. Connect the sidestream CO
2
module into the CO
2
connector on the monitor’s
right panel.
b. Attach the sidestream sampling lime to the inlet port located on the metal
container on the front of the CO
2
module. You will hear a click when properly
inserted.
c. Connect the calibrated flow meter to the exhaust port of the module after the
monitor is warmed up and all messages have cleared.
d. Verify that the flow rate is 50 ml/min ±10ml. If the measured flow rate is outside
the specified limits, remove the CO
2
module form use and contact a Mediana
Technical Service Department.
5. Test #3: Occlusion
a. Block the exhaust port while the sidestream CO
2
sensor module is runing.
b. Verify that the “CO
2
- Occlusion or leak” message displays.
