Special Assignment on Layout Types

Operating rooms $($OR$)$ are facilities within a hospital where surgical operations are carried out in a sterile environment. Historically, the term "operating theatre" referred to a non$-$sterile, tiered theater or amphitheater in which spectators could watch surgeons perform surgery. Operating rooms had a raised table at the center for performing operations. Operating rooms are spacious, easy to clean, and well$-$lit, typically with overhead surgical lights, and may have viewing screens and monitors. Operating rooms are generally windowless and feature controlled temperature and humidity. Special air handlers filter the air and maintain a slightly elevated pressure. Electricity support has backup systems in case of a black$-$out. Rooms are supplied with wall suction, oxygen, and possibly other anesthetic gases. Key equipment consists of the operating table and the anesthesia cart. In addition, there are tables to set up instruments. There is storage space for common surgical supplies. There are containers for disposables. Outside the operating room is a dedicated scrubbing area that is used by surgeons, anesthetists, ODPs $($operating department practitioners$),$ and nurses prior to surgery. An operating room will have a map to enable the terminal cleaner to realign the operating table and equipment to the desired layout during cleaning.
