There’s a decent chance that, at some point in your life, you’re going to require surgery. To the average person, the construction of an operating room may seem just like another part of medical construction. You’ll soon find that operating room construction is likely far more complex than you think. In this article, we’re going to look at the different sections constructed to create a proper operating room facility and the varying levels of restriction. 

Procedure Rooms

Despite the name, the Procedure Room is not where the most sensitive procedures happen. It is instead a place where less invasive procedures can occur. This is a place for duties that don’t demand an aseptic field, but where sterile instruments may still be used. Local or general anesthesia is used in this section classified as “unrestricted”, but none that require specialized ventilation. 

Operating Rooms

Also known as the “OR”, this is an area restricted to unauthorized personnel in order to keep the space as sterile as possible. This aseptic bubble is where the most invasive procedures take place. All kinds of anesthesia are utilized — provided that the proper measures for ventilation take place.  

Hybrid Operating Rooms

There are occasions where some semi-sterile equipment needs to be utilized during a surgical procedure, such as specialized imaging equipment. For these procedures, a hybrid operating room is used. Balancing cleanliness with utility, all of the operating requirements for personnel are enforced. 

Restricted Areas

Restricted areas are specially protected from any unregulated traffic for the sake of keeping the different areas aseptic. These zones require specialized passageways, adopting certain levels of garb, levels of cleanliness, and only thoroughly aseptic equipment. 

Semi-restricted Areas

The semi-restricted areas flank restricted areas, such as an operating room. These zones are largely where personnel can scrub in, don the appropriate garb, sterilize equipment, and the like. 

Patient Care Section

Patient care sections exist to meet the needs of patients preparing for or in immediate recovery from surgery. While a certain level of cleanliness is maintained, it is not on the level of restricted areas. At times, these are typically open spaces that contain “soft walls” in the form of privacy screens or other dividers. In other instances, patient recovery rooms are considered patient care sections.
