Summary

In this article the toolbox (v.3) was used to assess the influences of a range of technical and physiological factors on respiratory signals extracted from the ECG and PPG. Respiratory signals were extracted from the Vortal dataset (young and elderly subjects) using a wide range of techniques. The correlations of each extracted respiratory signal with a reference respiratory signal were calculated. This allowed us to investigate the effect of several technical factors (including site of PPG measurement, type of recording equipment, input signal (ECG or PPG) and sampling frequency), and physiological factors (including age, gender and respiratory rate) on the respiratory signals.
