Overview

The BIDMC dataset is a dataset of electrocardiogram (ECG), pulse oximetry (photoplethysmogram, PPG) and impedance pneumography respiratory signals acquired from intensive care patients. The dataset is intended to be used for evaluating the performance of algorithms in real-case operating conditions. This dataset is a very small subset of the Physionet’s MIMIC II Waveform Database Matched Subset, which contains all MIMIC II Waveform Database records that have been associated with the MIMIC II Clinical Database records. Read more about the overall dataset here.

Details

The dataset comprises 53 8-minute recordings of ECG, PPG, and impedance pneumography signals (sampling frequency, fs = 125 Hz) acquired from adult patients (aged 19-90+, 32 females). Those in the dataset were randomly selected from a larger cohort of patients who were admitted to medical and surgical intensive care units at the Beth Israel Deaconess Medical Center (BIDMC), Boston, USA. Two sets of annotations (performed manually and independently by two research assistants) of individual breaths of the impedance pneumography signal can be used to derive reference respiratory rate values.
