Reservoir analysis for BPplus files bpp_Res2. Matlab scripts to read BPplus files (*.xml) and perform reservoir analysis, pressure-only wave intensity analysis and estimate some other hemodynamic parameters from blood pressure waveforms.
This is beta 4 version and hasn't been subjected to extensive testing
Method for wave intensity analysis is based on: Alun Hughes, Chloe Park, Anenta Ramakrishnan, Jamil Mayet, Nish Chaturvedi, Kim Parker. Feasibility of estimation of aortic wave intensity using non-invasive pressure recordings in the absence of flow velocity in man. Front. Physiol., 2020; 11: 550. https://doi.org/10.3389/fphys.2020.00550
I am grateful to Richard Scott for information about variables in the BP plus XML file and some code suggestions.
Known bugs
- identification of end-systole unreliable. SEVR estimates dubious when this fails.
