The aim of this study was to analyse the physiological strain of nurses during the three shifts (Morning, Afternoon,Night) in relation to the specific microclimatic conditions and job activities. 8 professional nurses (6 female and 2 male), aged between 21 and 38 years (rnean 29. 8 ±5. 6 years), having from 3 to 18years service, were monitored throughout a complete working cycle of 4 days. They worked on a three shift system at fast rotation. Their working environment was an independent unit for intensive care and expert surgical treatment which was entirely air conditioned. The observation indexes included: twenty-five blood parameters, ten urine parameters, net cardiac cost and relation cardiac cost, etc. The results of the investigation have not envidenced serious alterations of the psycho-physical conditions of the nurses, but do pointed out some problems pertaining both to the environmental and physiological conditions.展开更多

Manufacturing, mining and other large industrial operations often run around the clock and their employees report for work in shifts. The huge number of variables and the amount of knowledge that needs to be structured, integrated and synthesized forces the need for a system analysis process that is able to deal with such complexity. Work flexibility is a very important issue in Chile and in the rest of the world. One of the main problems of a flexible work process is handling shiftwork systems with their economic, health, social, family and environmental consequences.展开更多
