Work and Heart Disease
II. A Physiologic Study in a Steel Mill
Knowledge of the cardiovascular requirements of various types of work is essential in making work recommendations for cardiac patients. In a previous study the stresses of work in a light metal manufacturing plant were shown to be small. The present study is an evaluation of the physiologic requirement of a typical day's work in an open-hearth furnace and other areas in a steel mill. The oxygen consumption, pulmonary ventilation, respiratory rate, and other physiologic responses in cardiac patients are compared to those of normal subjects performing the same tasks.
