Respiratory Rate Algorithms

Algorithms to estimate respiratory rate (RR) from electrocardiogram (ECG) and photoplethysmogram (PPG) signals.

---

Overview

Research into respiratory rate algorithms has been hindered by a lack of open-source algorithms. Consequently, one aim of this project is to provide open-source algorithms to facilitate future research. As stated in the licence accompanying the source code, the algorithms are not intended to be fit for any purpose. Instead, they act as an platform from which researchers can develop algorithms.

Resources

The following resources are provided:

• Algorithm Source Code: The latest version of the toolbox of algorithms.
• User Manual: A helpful resource for new users of the toolbox.
• Github Repository: A repository of all versions of the toolbox, past and present.
