A room (which may be a “room within a room”) with environ¬ mental controls which prevent bacteria and dirt from coming in or going out. This is accomplished by using a filtered air supply and by providing methods for manipulating the patient without direct contact. Ports in the “room” permit persons wearing sleeved rubber gloves or using special devices to perform tasks within the room.
A controlled environment facility in which all incoming air passes through a filter capable of removing 99.97% of all particles 0.3 μ m and larger. The temperature, pressure, and humidity in the room are controlled. Clean rooms are used in research and in controlling infections, especially for persons who may not have normally functioning immune systems (e.g., individuals who have been treated with immunosuppressive drugs in preparation for organ transplantation).
