Ending the Stacked Volume Test
To end the Stacked Volume test:
1. Either click the
STOP button or let the Stacked Volume test end following the
number of requested breaths.
2. Click the Print button to print a final report for the Stacked Volume test.
3. Click the New Test button to start a new Stacked Volume test.
Serial Communications
The Analyzer communicates with a PC through a serial (COM) port. If the Analyzer is
connected to a computer and turned on when the software is started, the software
automatically detects which COM port the Analyzer is on and then initiates
communications between the Analyzer and your PC.
Selecting COM Port
While running VT for Windows the user may select Com Port from the
Communications menu to change communications settings.
Selecting the Serial Communications Mode
The Analyzer has four modes for data transmission via the serial port, available from the
Communications menu. The currently selected mode shows a check mark next to its
name.
Test Parameter –the parameter that was chosen for running this test; this value does
not change during the test.
Wave Form – starts the continuous transmission of waveform data from the Analyzer;
flow, volume, airway pressure, auxiliary pressure, and differential pressure data are
received at a 50 Hz rate.
Both – starts the automatic transmission of both waveform data and parameter data, as
described above.
Parameters – start the automatic transmission of parameters that are calculated at the
end of a breath; these parameters are calculated on a breath-to-breath basis.
Note
No parameters are calculated for a breath if a zero occurs during that
breath.
None – selects no data transmission; this stops all automatic data transmissions from the
Analyzer.
