The operating room typically contains a monitor that displays vital signs, an instrument table, and an operating lamp. Anesthetic gases are piped into the anesthetic machine. A catheter attached to a suction machine removes excess blood and other fluids, which can prevent surgeons from seeing the tissues clearly. Fluids given by vein, started before the person enters the operating room, are continued.
