Abstract
The purpose of this research is to clarify how to show imformation about a patient to an anesthesiologist at an operating room. At an operationg room, many monitors for general care are in disorder. They might cause an anesthesiologist to overlook something important about a patient and fatigue with finding information from many monitors. In this research, we try to approach this subject in two point of view, contents and shape of a monitor. We propose using HMD(head mounted dispray) to show imformation about a patient because it can show imformation in an anesthesiologist's field of vision.
