Figure 7: Tissue oxygen partial pressure (left) and tissue temperature (right) measured at a tissue depth of 2 cm on the postoperative days 2 and 10 in the group with water-filtered infrared-A (wIRA) and visible light (VIS) and in the control group with only visible light (VIS) (abdominal operations, Study Heidelberg).

Values are presented as minimum, 25%-percentile, median, 75%-percentile and maximum (box and whiskers graph with the box representing the interquartile range; from [4], adapted from [7], [37]). During irradiation with wIRA(+VIS), the tissue oxygen partial pressure rose markedly by more than 30% and the tissue temperature rose markedly by approximately 2.7C, whereas both variables remained unchanged in the control group.
