Airborne Precautions

guidelines recommended by the Centers for Disease Control and Prevention for reducing the risk of airborne transmission of infectious agents. Airborne droplet nuclei consist of small-particle residue (5 μm or smaller in size) of evaporated droplets that may remain suspended in the air for a long time. Airborne transmission occurs by dissemination of either airborne droplet nuclei or dust particles containing the infectious agent. Microorganisms carried in this manner can be widely dispersed by air currents and may be inhaled or deposited on a susceptible host from the source patient. Special air handling and ventilation are required to prevent airborne transmission. Airborne precautions apply to patients known or suspected to be infected with epidemiologically important pathogens that can be transmitted by the airborne route. Examples include measles (rubeola), varicella zoster virus infections, Legionella infection, disseminated zoster, and tuberculosis. Compare Contact Precautions, Droplet Precautions. See also Standard Precautions, Transmission-Based Precautions.

airborne precautions

Infection control precautions for airborne pathogens, which are over and above “standard precautions”:
• Patient placement in a private room.
• Respiratory protection for staff members.
• Limiting the amount of time that the patient is transported.
Pathogens transmitted by airborne droplets Measles, tuberculosis, varicella.

Measures taken to prevent transmission of infectious agents by airborne droplet spray. Airborne precautions include use of masks and air filtration systems.

Droplet precautions should be added to the standard precautions when providing care to patients with symptoms of acute respiratory infections; contact precautions and eye protection should be added when caring for probable or confirmed cases of MERS-CoV infection; airborne precautions should be applied when performing aerosol generating procedures.
They highlight the need to follow standard precautions for specimen procession and handling, and they suggest additional steps to follow with regard to contact, droplet, and airborne precautions as they pertain to healthcare workers.
Both the World Health Organization (WHO) and the CDC recommend that healthcare facilities utilize airborne precautions, in addition to standard and contact precautions to deal with the possible spread of MERS, because of the similarity between the MERS Coronavirus and SARS Coronavirus, which is known to be transmitted through the air.
Airborne precautions for protection against inhalation of tiny infectious droplet nuclei:
Airborne precautions should be taken for all suspected cases of measles.
Strict infection control measures must be instituted to prevent the spread of this viral infection, including contact and droplet and airborne precautions.
Airborne precautions, including possible use of isolation rooms with negative pressure to keep airborne traces of the infection from traveling to patients or visitors and use of respirators for suspect SARS patients
Airborne precautions, including an isolation room with negative pressure relative to surroundings and the use of an N-95 respirator for persons entering the room.
34] The AFB smear is used to assess infectiousness and the need for airborne precautions.
Transmission-Based Precautions, which include Airborne Precautions, Droplet Precautions and Contact Precautions, are for patients with documented or suspected contagious pathogens.
Droplet precautions should be added to standard precautions when providing care to patients with symptoms of acute respiratory infection; contact precautions and eye protection should be added when caring for probable or confirmed cases of MERS; airborne precautions should be applied when performing aerosol generating procedures.
