Notas: Sumario: The present study was designed to assess the utility of end-tidal PCO2 (peak concentration of carbon dioxide in a single breath of exhaled air) as an index of psycholphysiological activity during performance of a computer-based task and during relaxation. Eleven data-entry operators were monitored continuously for three consecutive, 6 hour work days under the following conditions: during a self-relaxation baseline period; during an abbreviated progressive muscle relaxation period; and during a period of computer-based data-entry work. End-tidal PCO2, respiration frequency, and cardiac inter-beat interval were monitored continuously during the three conditions of the studyRegistros relacionados: En: Ergonomics. - London and Washington. - Vol. 37, nº 2, February 1994 ; p. 245-254Materia / lugar / evento: Ergonomía Pantallas de visualización de datos Estrés Ambiente de trabajo Dióxido de carbono Psicofisiología Otros autores: Ley, Ronald
