Anyone who goes into the room should wear a surgical mask.Ī.D.A.M., Inc.Illnesses that require droplet precautions include influenza (flu), pertussis (whooping cough), mumps, and respiratory illnesses, such as those caused by coronavirus infections including COVID-19.When a person talks, sneezes, or coughs, droplets that contain germs can travel about 3 feet (90 centimeters).Anyone entering the room who may touch the person or objects in the room should wear a gown and gloves.ĭroplet precautions are used to prevent contact with mucus and other secretions from the nose and sinuses, throat, airways, and lungs.These germs can cause serious infection in the intestines or lungs. Some of the germs that contact precautions protect from are C difficile, norovirus, and COVID-19.Contact precautions help keep staff and visitors from spreading the germs after touching a person or an object the person has touched.Anyone who goes into the room should put on a well-fitted respirator mask before they enter.Ĭontact precautions may be needed for germs that are spread by touching. ![]() People who have these germs should be in special rooms where the air is gently sucked out and not allowed to flow into the hallway.Germs that warrant airborne precautions include chickenpox, measles, and tuberculosis (TB) bacteria infecting the lungs or larynx (voicebox).Airborne precautions help keep staff, visitors, and other people from breathing in these germs and getting sick.They may need to wear a mask when they leave their rooms.Īirborne precautions may be needed for germs that are so small they can float in the air and travel long distances. Patients should stay in their rooms as much as possible while these precautions are in place. Stop following these precautions only when that illness has been treated or ruled out and the room has been cleaned. Some infections require more than one type of transmission-based precaution.įollow transmission-based precautions when an illness is first suspected. Transmission-based precautions are followed in addition to standard precautions. This will reduce the risk of contaminated air finding its way back into non-contaminated areas through a back-draught situation.Transmission-based precautions are extra steps to follow for illnesses that are caused by certain germs. The exhaust air ducts for isolation rooms should be independent from the building’s air exhaust system. To maintain negative pressure, the exhaust system needs to remove more air than what is being supplied into the room. Magnehelic gages should be installed to ensure negative pressure relationships are held.Ī dedicated exhaust system should be provided from the isolation room. It is imperative that the isolation room keeps negative pressure to the anteroom, and the anteroom keeps negative pressure to the surrounding area, to ensure infectious particles do not escape from either room into the surrounding areas when any of the doors are open. For Class N isolation rooms, due to the negative pressure relationship between the isolation room and the surrounding area, separate doors can be provided for the ingress and egress of the patient’s bed directly in and out of the isolation room. The anteroom provides access to the isolation room for staff and visitors. The door into the anteroom from the isolation room should be self-closing, and should swing into the anteroom. When designing an isolation room, make sure the anteroom has enough space for storage and application of PPE. ![]()
