Repeated Resuscitation: How Lifesaving alters Lifetables

How does saving lives affect the force of mortality and lifetable statistics? How can the progress being made in reducing the force of mortality be interpreted in terms of lifesaving? How many times can a person expect to have his or her life saved as a result of this progress? We develop a model to answer these questions and illustrate the results using U.S. mortality rates for 1900 and 1980 and as projected for 2050.
