Transcutaneous pO2 of volunteers during hyperbaric oxygenation

Continuous transcutaneous pO2 measurements (tcPO2 measurements) were performed in healthy volunteers who were breathing air and oxygen under hyperbaric conditions (max. 4 ata). The results show a close correlation of PO2 values measured by the noninvasive method, in blood from discret arterial punctures, chamber PO2, respectively, the PO2 of the inspiratory gas mixture which was checked up to maximal values of 2,200 mm Hg. The PO2 in the arterial blood samples was measured immediately after the puncture insight the hyperbaric chamber using a specially designed through electrode.
