Summary

We have shown that there are good correlations between transcutaneous determinations of pO2 and “conventional„ arterial blood samples. A systematic difference between values from the two methods was found.

We examined volunteers with various levels of maximal work capacity during exercise with transcutaneous methods. The pO2-values were registered in 15-sec-steps with a microcomputer together with respiratory parameters and heart rate.

A decrease in pO2 was found in well-trained athletes during hard exercise. pO2 tends to increase in patients with reduced work capacity. In normal untrained persons, little change was noted.

The observed changes are discussed together with ventilatory and cardiocirculatory values measured. Variations in pO2 during exercise are dependent on changes in ventilation, cardiac output and venous oxygen content. The relationships between these factors are considered.
