✦ Synopsis
For examination of industrial dust-diseases of the lung, sensitive methods of testing pulmonary and cardioeirculatory functions are used with clinical and radiological examinations. The determination of arterial blood gases before and after difined work is an appropriate criterion for respiratory function.
225 male and 121 female workers were examined to obtain standard values for arterial oxygen (PaOe) and carbon dioxide (PaCO~) partial pressures. The selection conformed to clinical and whole-body plethysmographie criteria. Arterialized capillary blood has been analysed before and after 5--6 rain of modified exercise (Modification in regard to sex, bicycle ergometer, sitting position).
Standard deviations for PaO 2 and PaCO~ at rest are s ~ ~ 6,3 to s ~ ~ 11 mm Hg resp. s = -V 0,6 to s = ± 1,6 mm ttg without a tendency to fall off towards the end of the exercise. The mean differences in PaO~ at rest and during work vary from --0,8 to ~2,2 mm Hg for males, and from --4,2 to A-4,6 mm Hg for females Statistically there is no difference due to age. The average PaO~ increase during work is 0,9 to 1,6 mm Hg during exercise and is statistically significant for nearly every age increment of 5 years.
Statistical evaluation has confirmed that Pa02 is dependent upon age. In those employed in industry for every 10-year increment, the average decrease in Pa02 approximately 3 mm tIg. It is also statistically significant that in men PaCO 2 increases 0,2 mm Itg for every age increment of 10 years. There is no particular variation in either PaO 2 or PaCO 2 with sex.
Zusammen/assung. Zur Beurteilung beruflich bedingter
Staublungenerkrankungen wird seit Jahren die subtile Austestung der pulmonalen sowie kardiozirkulatorischen Fnnktion neben der klinisehen und rSntgenologisehen Bewertung ge-forder~. U.a. gelten Ergebnisse arterieller Blutgasanalysen vor nnd gegen Ende dosierter Arbeitsbelastung dabei als geeigneter MaBstab ffir die Gesamtfunktion der Atmung. Untersucht wurden 225 mgnnliche und 121 weibliehe Arbeitnehmer im Hinblick auf die Gewirmung yon Normwerten fiir den arteriellen Sauerstoff-(PaO~-) und Kohlendioxydpartialdruek (PaC02). Die Auswahl erfolgte definiert nach klinischen
