Functional Checkout Procedure: FECG Test
15. Set the simulator’s
ECG Rate switch to the ∆15 position. Verify the following
on the monitor:
The FHR1 value oscillates by 15 BPM.
The FHR1 heartbeat indicator ( ) flashes for each input signal.
The ECG “beep” is heard from the rear panel speaker.
The recorder prints an oscillation of 15 BPM between 115 and 130 BPM on
the top grid of the strip chart paper. (Refer to Figure 6-5.)
16. Repeat step 15 for the rate value of ∆22. The result should be the same as step
15 except that the FHR1 value oscillates by 22 BPM and the recorder prints an
oscillation of 22 BPM between the 108 and 130 BPM on the strip chart recorder
paper.
17. Set the simulator’s
ECG Rate switch to the ∆27 position. Verify the following
on the monitor:
The FHR1 value oscillates by 27 BPM.
The FHR1 heartbeat indicator ( ) flashes for each input signal.
The ECG “beep” is heard from the rear panel speaker.
The recorder does not print any oscillation.
18. Access the monitor’s Install Options service mode screen and set the ECG
Artifact Elimination back to OFF.
19. Set the simulator’s
ECG Rate switch to the MANUAL position and the Manual
Adjustment
knob to the fully counterclockwise position. Disconnect the ECG
simulator sub-cable from the monitor’s y-adapter cable. Verify the following
on the monitor:
The FHR1 value and mode are both blank.
The recorder stops printing heart rate data on the strip chart paper.
The recorder prints the message CARDIO INOP on the center margin of the
strip chart paper after approximately 30 seconds.
20. Set the simulator’s
ECG Mode switch to the OFF position.
