TROUBLESHOOTING

Power Graph

The Control Unit monitors and presents a historical graph of the ultrasound power delivered to the EKOS Device(s)� The percentage of the
maximum average power actually delivered by each of the two channels, is plotted over time on the power graph�
Warning: The Control Unit user interface presents a historical graph of the ultrasound power delivered� The power data should not be
used for diagnostic purposes� Diagnosis of drug/ultrasound therapy should always be made using other clinical diagnostic tools (e�g�,
fluoroscopy)� An incorrect diagnosis could result in prolonged therapy or inadequate therapy�

Reading the Power Graph

1� To view the power graph, press the Graph tab
Figure 35. Power Graph Menu Tab
2� The power graph displays the power information for each channel with a 6 hour, 12 hour, or 24 hour time scale� As runtime increases
the power graph will automatically update to the most appropriate time scale�
3� The percentage of the maximum average power is plotted in the graph�
4� The graph and power data will be displayed as zero if the therapy is stopped for any reason (i�e� stop button pressed, cables
disconnected, channel made inactive)� See the figures below for examples of a power graphs�
5� The power graph shows the total runtime for the channel, not for the device� If possible, always reconnect devices to the same
channels they started on� If two devices are switched from one channel to another, the runtime will reflect the total amount of time
that specific channel delivered therapy regardless of the device currently connected�
Screen Layout – Power Graph
Power Graph information is provided for each channel independently showing percent of the maximum average power for the duration of
the therapy� Additionally, the current state of the device is shown by the colored channel icon (see Figure 36 and the Table 16)�
