Original traces from the same subject showing tHb and THI responses to 40-mmHg venous occlusions subsequently recorded on the biceps brachii muscle belly at the original site (a) and after lateral displacement of 1 cm (b). Note the different response of THI, attributed to a small vein in the sample volume in (b). Vertical dashed lines indicate start of cuff inflation and deflation.
