When there is an anteroom, airflow should be from the corridor into the anteroom, and the anteroom into the patient’s isolation room. Therefore, the negative-pressure isolation room is designed to help stop an infection from spreading from an infected patient to others in the hospital. A negative-pressure room is intended to isolate a suspected patient or has been diagnosed with an airborne infectious disease. ![]() Individual control and equipment decisions come together in the designs of the negative and positive pressure rooms themselves. This article explains some of the requirements for building hospital isolation rooms and the considerations that should be made. The false wall provides a way of finding service points while preserving the integrity of differential air pressures because of the room’s external lining not being penetrated. ![]() In some instances, the number of service penetrations in partitions and ceilings may suggest introducing a false wall or additional partition. When an anteroom is required, it must have self-closing doors and sufficient area to allow for the donning or removing personal protective equipment (PPE).Īn assessment of the service requirements of the hospital isolation room should be made to determine the practicality of sealing junctions at penetrations to ceiling and wall linings. This requirement should be determined by the proposed operational policy and be included at an early stage of the design process. Isolation rooms don’t always require an anteroom. Isolation rooms are frequently used in hospitals and other healthcare facilities, where controlling the spread of infectious diseases is essential to keep patients, personnel, and visitors safe and healthy. ![]() This may be achieved by controlling the quantity and quality of intake or exhaust air, maintaining different air pressures between neighboring areas, designing airflow patterns for specific clinical procedures, diluting infectious particles with large air volumes, and air filtration. An isolation room controls the airflow so that the number of airborne infectious particles is minimized make the risk of cross-infection of other people within a healthcare facility highly unlikely.
