Case Studies

Case Studies

This collection of wiki pages provides instructions on how to reproduce the case studies of the pulse wave database reported in this article. These are provided for two reasons.

Firstly, these case studies provide a starting point for using the database. researchers may find it useful to start with the code used for these case studies, and then to adapt it for their own research.

Secondly, these instructions allow other researchers to reproduce the work described in this article, ensuring that the methodology is documented in its entirety.

Requirements

The items required to reproduce the case studies are:

• pwdb code, the code used to analyse the database in the case studies.
• Matlab ®, the software for which the pwdb code is written.
• PWDB data in Matlab ® format, a single file containing the important data from the Pulse Wave Database.

Steps

The three case studies can be reproduced by following the instructions for each case study:

1. Pulse Pressure Amplification Case Study: An investigation into the determinants of pulse pressure amplification, which highlights the two main mechanisms responsible for changes in pulse pressure amplification with age.
2. Aortic Stiffness Case Study: An assessment of methods for assessing aortic stiffness from the finger PPG pulse wave, with key findings to inform the design of future clinical assessments of these algorithms.
3. Cardiac Output Case Study: An evaluation of algorithms for estimating cardiac output from arterial blood pressure waveforms, with implications for future clinical evaluations of algorithms.
