This example of a theatre organizational chart shows the structure of the operation theater. An operating theater is a facility within a hospital where surgical operations are carried out in an aseptic environment. These theatres will contain lots of specialist equipment. Still, every operating theatre has bright lights, an operating table for the patient to lie on, and Electrocardiograph Machine to monitor a patient’s heart rate. Surgical suction machines remove blood from around the organs the surgeons are treating, as shown in this example of a theatre organizational chart. Not all hospitals have operating theatres, and some larger hospitals might have more than one in what is called operating suites.
