Abstract

This article applies a theoretical framework developed by the late American sociologist Anselm Strauss to the discovery of a new resuscitation technique, closed-chest cardiac massage. The discovery, which took place in the laboratories of Johns Hopkins University between 1956 and 1960, is analyzed as the collective management of a trajectory over time. The article follows the discovery trajectory from its origins in defibrillator research to the establishment of closed-chest cardiac massage and cardiopulmonary resuscitation as a universal life-saving method. The analytical focus on the experimental, clinical, and promotional activities performed by the different actors interacting with the emerging technology allows one to critically question the value of concepts such as closure, stabilization, and black boxing in sociology of science and technology. Instead of prematurely freezing the analysis of technoscience, a trajectory conceptual framework emphasizes the ongoing dynamic between actors and medical technology to define the scope, effectiveness, and multiple interpretations of the technology-actor interaction.
