title: [Quantification of combined effect of physical-chemical factors by the parameters of human external breathing].
abstract: Quantitative evaluation of the combined effect of physical-chemical factors, i.e. hypodynamia, ionizing radiation at small doses, noise, vibration, and altered gas composition of the atmosphere was accomplished during 3- and 15-day experiments with exposure of 11 volunteers (factually 16 subjects) to specified environment in hyperbaric chamber by the parameters of external breathing. Established was an integral parameter of quantitative assessment, functional strain index, variations of which are fully consistent with the alterations in external breathing parameters. Symptoms of a summed effect can be deduced from shifts in external breathing as a result of combined action of a set of diverse factors.
