QA-VTM Plug-In Read Me

ansur QA-VTM Plug-In is a product facilitating automatic test and inspection with the use of the QA-VTM Ventilator Tester for testing ventilators.




This read me file contains last minute information for Fluke Biomedical's ansur QA-VTM version 2.2.1.




This chapter describes the changes made between each new released version.

Release 2.2.1

  • Recompiled with the new version of a component compatible to windows Vista.

Release 2.2.0

  • Altered names and graphics for Fluke version.
  • Added support for ansur V2.
  • Fixed a problem where high pressure test values where reported incorrectly.

Release 2.1.3

  • A predefined trend can no longer be stopped and deleted.
  • It is now possible to change unit on Temperature. Default Temperature unit is changed to Celsius.
  • Fixed a problem where the pressure reported on leakage test and low pressure test was 10 times bigger than the actual measured pressure.
  • Updated report so that the first trend sample is printed on the right place.
  • Fixed a problem where the first trend sample was incorrect.
  • Scale boundaries employed in waveforms are now centered around the graph.
  • Tidal Volume is now displayed with three decimals.

Release 2.1.2

  • A problem causing ansur to hang when running a QA-VTM test using ansurMLC V2.1.8 on Windows 98 was fixed.
  • Test guide now resets correctly if a test instrument cannot be found.

Release 2.1.1

  • Ventilator test now supports 32-bit results streamed by new and improved FW/HW. Backwards compatibility has been maintained. The plug-in auto-detects firmware revision and handles the results accordingly.
  • Implemented support for new ventilator test parameter 'Atmospheric Pressure' This parameter is only applicable when running a firmware higher than or equal to 3.0. Should the user attempt to run a test including 'Atmospheric Pressure' on old firmware, the plug-in will advise him/her of this and simply ignore that parameter.
  • Bugfix: Attempting to run a ventilator test on Windows 2000 as a user with low access privileges would cause the plug-in to bail out. This was due a DLL not being properly registered for restricted users has now been fixed.

Release 2.0.4

  • Trends do not start sampling until a positive Breath Rate has been detected, thus solving the problem with erroneous zero-values. 
  • Support for QA-VTM firmware 3.0 and above where pressure resolution is 1/1000 and not 1/100. Plug-in auto-detects firmware version and acts accordingly.

Release 2.0.3

  • Reverted performance enhancement from version 2.0.2 where X and Y-scaling settings were not save to XML structure, as this affected printed reports. 
  • Bugfix: Incorrect legend text for printed reports.
  • Added 'Volume calculation' frame to plug-in preferences 'Advanced' tab. 

Release 2.0.2

  • Bugfix: Test Guide was not updated if entire test had been viewed in full-screen mode. Consequently, no values were displayed in Test Guide. 
  • Bugfix: Trend values were displayed incorrectly (by a factor of 100)
  • The 'Reset calculations' option is no longer available when a test is not performing. 
  • 'Detect level' legend setting was not properly maintained for flow waveforms and snapshots. 
  • Trends and snapshots are now deleted from results structure whenever user flags a test as 'Not applicable'
  • Whenever user skips a test, the entire results structure for that test is deleted 
  • User is now prompted for confirmation before skipping or flagging a test as 'Not applicable', so that results are not accidentally deleted.
  • Bugfix: Snapshots and waveforms X-scaling were corrupted when viewing a trend parameter.
  • Oxygen level limits are now correctly detected and reported.
  • Performance enhancement: X and Y-scaling settings are no longer stored in XML stuctures if autoscaling is enabled.
  • Bugfix: Snapshot values from long test runs were not loaded correctly due to an overflow error. 
  • Legend text is now correctly placed on printed graphs.
  • Improved algorithm for calculating X-ticks on printed graphs

Release 2.0.1

  • Re-written routines for calculating volume. Volume is now reset to zero whenever both flow and pressure are under a given threshold.
  • Controls for setting this threshold can be found in the plug-in preferences 'Advanced' tab 
  • Auto-scaling of waveforms can now be limited to a given scaling boundary, so that noise is not zoomed in upon. The user may set these boundaries by manipulating the registry entries: ScaleFlowMin_mlSec, ScaleFlowSpan_mlSec, ScalePressureMin_cmH2O and ScalePressureSpan_cmH2O. Important note: These settings do not permit decimals. Consequently, values should be scaled by a factor of 100. E.g. 166,67 ml/sec should be entered as '16667' .
  • Fixed bug where incorrect data and scaling settings were preserved during truncate.  
  • Plug-in now uses Noise Level setting actively for the Flow Test; All values between N and -N are treated as zero. Earlier versions relied upon the QA-VTM to do this filtering,
  • Various minor fixes.
