Progress in medical care strongly depends on the development of pharmaceutical and medical technologies. Multi-disciplinary care by a medical team is required for the diversity of medical care. "Clinical engineering technician (CET) " is one of the national medical licenses in Japan. Many CETs are engaged in blood purification therapies. Team medical care, involving medical doctors, nurses, CETs, etc., in the hemodialysis field is useful for the early detection of complications in dialysis patients and provision of appropriate treatments. In some medical facilities, for example, progressive approaches such as appropriate nutritional guidance by a dietitian or exercise therapy by a physical therapist are practiced in advance. Clinical laboratory technologists (CLTs), furthermore, play an important role in team medical care for dial- ysis therapy. They can use ultrasonic equipment for vascular access management. Based on the results of the ABI and SPP measurements by CLTs, medical doctors can diagnose PAD in dialysis patients. [Review].
