Development of universal model for appropriate OT size Our major assumption was that the appropriate OT size should be arrived at by adding together the area occupied by surgical equipment and healthcare workers such as surgeons, nurses, and

clinical technicians, and their ‘traffic’, and the movement area – depending on the type of operation being performed. The area designated to a healthcare


worker was set as a circle with a 2 m diameter, compatible with a human’s height according to a model of the ideal


human body in ancient literature. (Fig. 1) The two-dimensional square may include the area physically occupied by the human body and that of the individual’s minimal movement. The remnant corners of the 2 m square outside the circle were designated as ‘for traffic space’. The area designated ‘for the patient’


was also set as a similar circle, with a 2 m diameter. The circle area was considered to comprise the area devoted to the patient and the operating table, the area within which the patient is positioned, and the area within the surgical and other theatre staff work during the procedure (Fig. 2). We set the size of the operating table as 0.6 x 2.0 m, again using the model of the ideal human body.

The shape of the ‘OT’ The equipment routinely used for operations, including the operating table, was incorporated into the model. Such equipment is considered to be ‘carried through’ the traffic space. Routine/ general surgery is generally performed by a surgeon, first/second assistants, an anaesthesiologist/assistant, and an
