![]() ![]() ![]() Airborne precautions are the highest level of isolation. 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. The door to the isolation room and the anteroom should never be open at the same time. It should be stressed that standard droplet and contact precautions should be strictly enforced. The wearing of correctly fitted surgical masks by coughing patients prevents dispersal of respiratory secretions into the air. Patients in airborne isolation need to be placed in a negative-pressure airborne infection isolation room (AIIR). It is detected in respiratory tract secretion, urine and stool.The use of negative pressure rooms may reduce the transmission of infection.The use of particulate filter respirators (PFR), such as P2 or N95, prevents the inhalation of small particles that may contain infectious agents transmitted via the airborne route.Airborne droplet nuclei can also be generated through aerosol-generating procedures (AGPs), such as intubation, suctioning, bronchoscopy, or the use of nebulisers.Īirborne precautions are based on evidence that shows that: These agents may be inhaled by individuals who have not had face-to-face contact with, or been in the same room as, the infectious individual. Airborne precautions are steps that healthcare facility visitors and staff need to follow when going into or leaving a patients room. Chapter 2: Transmission based precautions (TBPs) Contact precautions: Droplet precautions: Airborne precautions: Single room isolation in hospital settings. Airborne precautions, in addition to standard precautions, are used to prevent transmission of infectious agents that are disseminated through airborne droplet nuclei and remain infective over time and distance. ![]()
