Continuous direct tissue oxygen tension measurement by a new method using an implantable silastic tonometer and...

A new method of tissue oxygen tension measurement that is suitable for human use has been described. An implanted Silastic tube tonometer is combined with polarographic oxygen electrodes. The techniques of preparation, insertion, and measurement have been described. The advantages and disadvantages of this method have been considered in relation to established methods of tissue oxygen tension measurement. The method is suitable for clinical use and can be used to aid clinical decision-making.
