4.2.7 CO
2
Performance Test
This test checks the performance of the CO
2
measurement.
Tools required: nasal cannula.
Procedure:
1. Switch on the monitor.
2. Access CO
2
setup menu, and set the Work Mode to Measure.
3. Place the nasal cannula below the nose and normally breathe; check if the CO
2
measurement
waveforms are available on the monitor.
4. The displayed CO
2
concentration is supposed to be 34~40mmHg.
4.2.8 IBP Performance Test
This test checks the performance of the IBP measurement.
Tools required: patient simulator
Procedure:
1. Connect the IBP cable to the connector for channel BP2 on the patient simulator and to the
IBP connector on the monitor.
2. Set the simulator to 0 pressure and perform a zero calibration.
3. After completing the zero calibration, configure the simulator as P (static) = 200mmHg.
4. Perform a dynamic pressure test. Set the simulator to the following configuration:
- RADIALART 120/80
The tolerances for the measurement value provided by the monitor should be ±4 mmHg or
±4%.
4.2.9 C.O. Performance Test
This test checks the performance of the C.O. measurement.
Tools required: patient simulator
Procedure:
1. Connect the simulator to the C.O. module using the patient cable.
2. Configure the patient simulator as follows:
- Injection temperature: 0℃
- Computation Const: 0.542
