WORKSHOP REPORT
multiwire electrodes had been used by him to give depth-dependent and multi-site profiles of pO2 in the kidney, brain and other organs. A large number of data points were clearly necessary for any representative picture of tissue ~02, but inevitably, surface measurement was less distorting than the use of puncture techniques, and this may become a dominant approach in the future, particularly with the advent of reporter molecules for 02 which could be optically interrogated in an intact tissue. An important observation in the time domain was that while ~02 in local microenvironments drop as a result of hypoxia or a lowered haematocrit, recovery leads to ~02 values returning to their original relative values. This confirms that whatever the structure of the three dimensional 02 profile in a given tissue, it is by no means randomly arrived at, and possesses a stability with mechanisms for its conservation.
The Workshop gathered together a unique mix of expertise and skills, and combined with the enthusiasm and depth of the ensuing discussions, it could certainly be deemed a success. For the sensor Group, many questions remained to be answered about the nature of the bio-system being studied, not, at least, the formulation of such questions might be easier now. Hopefully, future dialogue will be able to range in more depth over basic issues. The list is a large one, but includes, continuous monitoring, pathophysiological correlates of biorhythms, tissue/blood interrelationships, requisite sensor characteristics (response time, stability, sensitivity, signal to noise ratio) and feedback design. If the learning process is a protracted one, this first step was certainly an enjoyable one.
