Figure 4From: Acute oxygenation changes on ischemic foot of a novel intermittent pneumatic compression device and of an existing sequential device in severe peripheral arterial disease tHb AUC changes for each single leg under study during the treatment with the two devices. Legend to Figure 4: a) GP, Gradient Pump device; b) SFC, sequential foot-calf device; tHbAUC, area under curve of total haemoglobin. The continuous lines connect tHbAUC values recorded each 5-minute period during the treatment (P1-7) starting from baseline (P0). Data refer to 12 patients/20 diseased legs for GP device, and 11 patients/18 diseased legs for SFC device.Back to article page
