LABORIE Goby Owner’s Manual GOBY-UM02 48
To change the Channel parameters or the Graph Range for the Lin PURR graph:
Refer to Figure 51 for a visual of the fields described.
Change the channel:
1. Click the drop-down button of the combo box beside the channel name to be changed.
2. Select the appropriate channel.
Change the Scale or Threshold:
1. Double click inside the appropriate text box.
2. Type a new value using the keyboard.
Change the Graph Range:
1. Click the Change button.
2. Select the new range.
Activate/Deactivate the Display Options*: Click the check box beside the appropriate option.
Color of Display: Select the Channel button. Press Color button.
* These Options are regions of discrimination to assist the clinician in categorizing the pressure/flow event.
The following list explains these regions:
• Pressure Flow Curve: This curve plots Uroflow and Pdet. It is similar to a URA curve, but LinPURR plots the pressure
channel on a horizontal axis and the flow channel on a vertical axis.
• URA Curve: Please refer to page 45.
• URA Region Border: These lines on the graph divide the obstructed, unobstructed, and equivocal regions.
• Detrusor Contractility: Detrusor Contractility is displayed as six regions marked in a left-diagonal fashion by the
following labels: VW, W-, W+, N-, N+, and S. The software looks at the dataset to determine the relative strength
of the bladder using Pdet and Flow as factors.
• Normalized Detrusor Contractility: Normalized Detrusor Contractility represents the pressure at which the
minimum "normal" bladder performance has been achieved on the Detrusor Contractility Scale. If this value is 0,
then a minimum pressure has not been achieved.
• OBI Pressure: This pressure represents the point at (50% of Qmax+2.4ml/s.)
• LinPURR Grade: To perform a LinPURR Grade, use the following 2 above data points:
o Pdet at max. Flow
o Pdet at min. flow
The LinPURR plot can show a rough estimate of the relative grade (0 to VI.)
The digital parameters for LinPURR can be viewed from the LinPURR Summary box.
To access the LinPURR Summary Box:
Click Summary from the LinPURR window (Figure 50). The LinPURR Summary window will appear.
To Change information in the LinPURR Summary Box:
To change any channel or pressure values in the boxes: Double-click the text box to be changed and type the new
information using the keyboard.
To Change the LinPUUR Grade or Detrusor Contractility: Select the appropriate option.
To Save the information for printing: Click Save Diagnosis. The numerical results of the LinPURR calculation will appear in
the info-Diagnosis section of the software.
• Click the Exit! button to close the LinPURR Summary.
• Click the Exit! button in the LinPURR plot window to close the LinPURR Plot Window.
