Signals PPG, ECG, respiration
No. Subjs 200 (100 Black, 100 White)
Protocol 200 critically-ill adults during routine clinical care. Data were measured using a bedside monitor at 125 Hz. Data were extracted from the MIMIC-III Waveform Database Matched Subset.

Importing the data into MATLAB

  1. Use the following MATLAB script to import the data: collate_mimic_perform_ethnicity_dataset.
  2. Modify the MATLAB script by inserting the up.paths.root_folder and up.paths.save_folder into the setup_up function.
  3. Note: The duration of recordings provided by the script can be adjusted with the up.settings.req_durn variable within the setup_up function.
  4. Note: The number of subjects in each group can be adjusted with the up.settings.no_subjs_per_ethnicity variable within the setup_up function.
  5. Run the MATLAB script to download the required files from PhysioNet, import the data into MATLAB, and collate the data into a single MATLAB data file, ready for analysis.
  6. (optionally) convert the dataset into WFDB and/or CSV formats using this MATLAB script: mimic_perform_dataset_converter
