3.7.3 Latency Template

Below this tab you are able to enter you own latency template values, relative to patient age and gender.
This Latency Setup permits you to enter latency values which will then be displayed as grey shaded areas
when you assign Waveform Markers on curves.
For these latency values to correspond to the type of patient being tested, latency values for a variety of
combinations of ages and gender must be entered.
Even though the unit may hold examples of latency values when delivered from the factory, it is highly rec-
ommended that each clinic enters their own approved latency values, as no international standardized data
exists.
1. Stimulus Here the different types of stimulus frequencies and transducer are selected.
2. Age and Gender As the characteristics of the curves change significantly for babies we have made four
divisions from 0 to 16 months of age. Patients older than 16 months are considered adults. There are also
variations between men and women. For this reason, the gender of the patient can also be added to the La-
tency Norm.
3. Waveform Markers This feature allows you to add the expected time values at which Waves I, III and V
normally occur. The boxes for "Deviation" define the width of the grey time bar which appears when you start
selecting the Waveform Markers on the curves. After specifying the desired Waveform Markers/Intensities,
hit the "OK" button and then "Yes" for saving the modified norm data.
Data entered here will also specify where the automatic function "Suggest Waveform Markers" will place its
suggested Waveform Markers. If you do not want this function to suggest Waveform Markers at e.g. Wave I
at low intensities, or in other situations where results are often difficult to obtain, do not enter normative data
for these Waveform Markers.
