2.5 Testing Each Parameter
Testing each parameter annually ensures the accuracy of the Trio Monitor. The following
tests should be used for verification of operation only. The following tests should not be
considered calibration procedures.
2.5.1 ECG and RESP
2.5.1.1 Test Equipment
• Patient Simulator
2.5.1.2 Test Procedures
1. Use a 5L patient cable and lead wires to connect a calibrated patient simulator to the
ECG connector of Trio.
2. Set ECG lead to lead II and ECG size to x1.
3. Check if ECG waveforms and RESP waveforms are displayed.
4. Set up the parameters of the simulator as follows:
HR=30 (gain × 4)
RR=15
5. Check if the displayed ECG and RESP waveforms, HR and RR values are correct.
6. Change the simulator configuration:
HR=240
RR=120
7. Check if the displayed ECG and RESP waveforms, HR and RR values are consistent with
the parameters set up on the simulator.
8. Remove ECG lead. In this condition, the Trio should immediately alarm and display
ECG LEAD OFF at the top right side of the Message Area.
2.5.2 NIBP
