<p>An analytical apparatus comprising a plurality of pulse-oximetry sensors (6, 8, 10) arranged to measure pulsatile signals at separate respective locations within the peripheral tissue of a body part and means (14, 16) for monitoring the measured signals. The apparatus may thus be used to detect localised abnormalities in peripheral blood oxygenation levels, indicative of existing tissue damage or the potential therefor.</p> |
