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.
- Recompiled with the new version of a component compatible to windows Vista.
- Altered names and graphics for Fluke version.
- Added support for ansur V2.
- Fixed a problem where high pressure test values where reported
- 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
- Updated report so that the first trend sample is printed on the
- Fixed a problem where the first trend sample was incorrect.
- Scale boundaries employed in waveforms are now centered around the
- Tidal Volume is now displayed with three decimals.
- 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
- 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
- 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.
- 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.
- Reverted performance enhancement from version 2.0.2 where X and
Y-scaling settings were not save to XML structure, as this affected
- Bugfix: Incorrect legend text for printed reports.
- Added 'Volume calculation' frame to plug-in preferences 'Advanced'
- Bugfix: Test Guide was not updated if entire test had been viewed
in full-screen mode. Consequently, no values were displayed in Test
- Bugfix: Trend values were displayed incorrectly (by a factor of
- 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
- 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
- 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
- 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.
