Oxygen tension measurements using an oxygen polarographic electrode sealed in an implantable silastic tonometer: a new technique.
Our new method is comparable to the standard, "open-end" tonometer system and incorporates all its abilities to monitor oxygen tension and perfusion. The new device has the advantage of being completely sealed, providing a true, continuous direct measurement over several days, with freedom of movement for the patient without operator attention and with improved stability of the electrode, which minimizes the drift artifacts previously encountered. These improvements will facilitate routine clinical monitoring of tissue oxygen tension.
