The history of the use of the pulmonary-artery catheter (PAC)illustrates a great deal about physicians' often uncriticalacceptance of technology in clinical applications. In 1956,Forssmann, Cournand, and Richards were awarded the Nobel Prizein Physiology or Medicine for the development of heart catheterizationand consequent discoveries in cardiac pathophysiology. Forssmannperformed the first right heart catheterization, on himself,in 1929. The catheterization work of Cournand and Richards atthe Bellevue Hospital Chest Service began in the 1940s, andit initiated a new era in cardiopulmonary physiology, providingimportant insights into hemodynamics, gas exchange, and heartlunginteractions.
