The cardiac pulsatility model (CPM) is a set of denoising regressors derived from PPG data and proposed in Kassinopoulos and Mitsis (2020).

Detailed Description

This metric is an adapted version of the RETROICOR regressors and MATLAB code can be found in mkassinopoulos/Noise_modeling_based_on_PPG.

Context / Motivation

I haven't dug into the code or preprint in too much detail, but according to the abstract the CPM model outperforms RETROICOR, so it could be useful.

Possible Implementation

We can probably translate the MATLAB code directly, as long as we integrate the original repo's license info (which we will probably need to request).
