PhysioNet

Since 1999, PhysioNet (http://physionet.org/) has offered free access via the web to large collections of recorded physiologic signals and related open-source software. This presentation offers an overview of PhysioNet and discusses its benefits to the global community of researchers, clinicians, educators, and students, with examples that include support of exploratory data analysis, development and validation of experimental methods, collaboration among geographically distant investigators, and stimulating rapid progress on specific questions via open research and engineering challenges.
