Data for Cardiac Output Estimation Studies

The file RECORDS in this directory is a list of the 120 MIMIC II Database records for which both ABP and TCO measurements were available at the time of the study. Within http://physionet.org/physiobank/database/mimic2db/ are subdirectories for each record, containing WFDB-compatible signal and numeric trend records. The ABP signals, sampled at 125 Hz, can be found in the base records, and the reference TCO measurements, occurring at irregular intervals, can be found in the associated 'n' (numeric trend) records. For example, the first entry in RECORDS is a40006; find the ABP signal in record mimic2db/a40006/a40006 [layout header], and the TCO measurements in record mimic2db/a40006/a40006n [header]. Note that the trend records contain samples of all trend variables at regular intervals of 1 minute; only the non-zero values of the CO trends represent TCO measurements.

The software in ../code/1extract/ can use these records to generate input files for the remaining software in ../code/.

The other files here contain additional clinical information for the 120 patients whose records are listed in RECORDS:
