MINIATURE ELECTRODE FOR DETECTING INTERSTITIAL TISSUE PH

摘要

Miniature pH electrodes are provided that simultaneously measure pH and temperature to a high degree of sensitivity, demonstrate low pH drift, are quickly and easily equilibrated, and can be stored and sterilized in a hydrated state. The electrodes function even when fully immersed in an electrically conductive fluid such as blood without loss of accuracy or sensitivity. The electrodes can be inserted in the wall of the heart to a predetermined depth to monitor interstitial tissue pH during surgery.
