Conjunctival monitor
First Claim
1. A method for monitoring blood and tissue gas or pH of a patient, comprisingplacing an optical blood and tissue gas monitor sensor tip adjacent to the palpebral or bulbar conjunctiva of said patient,wherein said sensor tip comprises at least one optical sensor fiber for detecting at least one blood and tissue gas or blood and tissue pH, andsaid sensor tip is connected with analysis and display components of a blood monitor system;
- andsaid sensor tip is adapted and configured to be held in place adjacent the palpebral or bulbar conjunctiva of the eye;
determining patient blood and tissue gas or pH values or both with said blood monitor system; and
recording or displaying said patient blood and tissue gas or pH values or both.
