IMPROVE Data Library
The IMPROVE Data Library consists of digital recordings of continuous monitored signals, clinical patient data and continuous patient state annotations. The continuous signals recorded typically are ECG (2 channels), systemic blood pressure, pulmonary arterial pressure, central venous pressure, airway flow and pressure and concentration of oxygen and carbon dioxide in the airway gases. In addition, EEG (2 channels) was recorded from 7 patients. The continuous signals are stored in the European Data Format. The other clinical data contains practically all the routinely available data in the intensive care, i.e. laboratory results, fluids and medication, nursing actions, patient state assessments and scoring, trend samples from the patient monitors (temperatures, heart rate, blood pressures, etc.) and intermittently measured variables (cardiac output, pulmonary capillary wedge pressure, etc.). In addition, the data is completed by continuous annotations which are made by a physician who stayed at the patientP2s bedside throughout the recordings. The annotation include patient state assessment, observations of possible sources of artifacts for the signals (coughing, patient movements, routinely non-recorded nursing actions, etc.). The clinical data and annotations are stored in ASCII format.
