Analysing PWV using the DSPW software (Indus Instruments)

TL;DR

This video provides a step-by-step guide on using the Doppler Signal Processing Workstation (DSPW) to analyze pulse wave velocity.

Transcript

hi this is a quick run-through showing the sequence of events clicks etc required to look at pulse wave velocity using the Doppler signal processing workstation or DSP W so I've got it loaded in front of me on this Windows machine and the first thing I'll do is check that the settings are correct so go to the setup window click on Doppler setup and...

Questions & Answers

Q: How do I ensure the software can properly analyze the Doppler signal?

Enable the "use F/R" setting in the Doppler setup to ensure the software can see the forward and other trace adequately.

Q: How can I adjust the size of the ECG waveform?

Go to the ECG setup and change the gain setting. A higher gain number will make the ECG waveform smaller.

Q: Can I rescale the waveforms for better visualization?

Yes, you can rescale the waveforms by clicking on the scale bar on the side of the screen. You can also move the entire waveform up and down for easy identification.

Q: How can I measure pulse wave velocity?

Use the analysis control window to measure distances between specific points on waveforms and interpolate them as pulse wave velocity. The video provides a detailed step-by-step process.
