#A NEGATIVE PRESSURE ROOM MANUAL#

A Manual of Laboratory and Diagnostic Tests. Tuberculosis- A dangerous pathogen that should contained in a negative pressure room. KEY TERMSĪnthrax- A dangerous pathogen that should contained in a negative pressure room.Įbola virus- A dangerous pathogen that should contained in a negative pressure room. Even when enforced, it is not as microbiologically efficient. This practice is very difficult to enforce. The only feasible alternative to a negative pressure room is quarantine and isolation. Morbidity and mortality ratesĭata on morbidity and mortality related to negative pressure rooms is not available. In a properly operating negative pressure room, the expected and normal result is containment of a potentially dangerous pathogen. Inadequate cleaning after occupancy puts subsequent occupants at risk of exposure to a potentially dangerous pathogen. Seal, pump or protocol failure destroys the negative pressure and increases the chances that pathogens will be released. Negative pressure rooms must be decontaminated before being cleaned after being occupied. Seals on vents and airlocks must be checked on a regular basis. AftercareĮntrance and egress protocols must be followed by all people that enter or leave a negative pressure room. Negative pressure rooms are used when the presence of an airborne pathogen such as tuberculosis is suspected.

Why am I being confined in a negative pressure room?Īll air exhausted from the room is routed through special filters that are designed to trap and contain pathogens.

This preserves the vacuum, maintains the negative pressure and prevents pathogens from escaping.

Two doors, separated by at least 6 feet, must be installed to create an airlock. In operation, the vacuum created stops the outflow of air, thus containing The room ventilation system must be equipped with a vacuum pump that must create a constant but relatively low level vacuum. All points if entrance or egress must be able to be tightly sealed so that air cannot pass by the seals. Negative pressure rooms require special construction. Air flow is controlled by airlocks for human travel and vacuum pumps for ventilation systems. Communications include doors and ventilations ducts. It is also intended to prevent the accidental release of pathogens into a greater space thereby protecting workers and employees in a hospital or other healthcare facility.Īll communications between a negative pressure room and adjacent spaces are controlled. DescriptionĪ negative pressure room is designed to confine pathogens to a small volume of space. Experts estimate that approximately 4000-5000 negative pressure rooms exist in hospitals throughout the United States. Official counts of negative pressure rooms do not exist. The purpose of a negative pressure room is to confine pathogens to sa single closed environment and to prevent the release of pathogens into other adjacent spaces. WHO PERFORMS THE PROCEDURE AND WHERE IS IT PERFORMED?Īn infectious disease or emergency physician usually admits patients to negative pressure rooms in hospitals or other healthcare facilities. Definition Purpose Demographics Description Diagnosis/Preparation Aftercare Risks Normal results Morbidity and mortality rates Alternatives DefinitionĪ negative pressure room is a volumetric space in which the internal atmospheric pressure is lower than the spaces into which it opens.
