Abstract

Photoplethysmographic study of peripheral circulation of the fingers is still widely used in occupational medicine. However, there is no unequivocal agreement on the normal reference values for photoplethysmographic (PPG) parameters. In order to identify physiological values of some of these parameters which could be used for differential diagnosis in subjects with occupational disease, 80 apparently healthy subjects were examined, chosen according to strict clinical and instrumental criteria. The subjects were divided in groups according to age and season of the year and underwent photoplethysmographic examination in basal conditions and after the cold test. The results reveal the following data: there is a wide interindividual variability in the PPG readings; no flattening of the wave was ever observed; the T.C./T.T. can be reliably evaluated with some reserve; recuperation time never exceeded 3 min; Raynaud's phenomenon or cyanosis were ever observed. Age seems to have a very limited influence on the PPG readings, and the climate in the various seasons appears irrelevant.
