![]() ![]() Aerosols can penetrate the respiratory system to the alveolar level. Airborne precautions are measures used to prevent, and control infection spread without necessarily having close patient contact via aerosols from the respiratory tract of one individual directly onto a mucosal surface or conjunctivae of another individual. Aerosols formed from droplet particles in this way behave as other aerosols. ‘Droplet nuclei’ are aerosols formed from the evaporation of larger droplet particles (see droplet transmission). They can remain in the air for long periods of time and can be carried over long distances by air currents.Īirborne particles can be released when an individual coughs or sneezes, and during AGPs. Airborne particles are very small particles that may contain infectious agents. The spread of infection from one individual to another by airborne particles (aerosols) containing infectious agents. Airborne precautionsĪ group of transmission based precautions to prevent the spread of airborne pathogens. Aerosols can be released during aerosol generating procedures (AGPs). ![]() They can remain in the air for extended periods of time and can be carried over long distances by air currents. Very small particles (of respirable size) that may contain infectious agents. The criteria for an AGP are a high risk of aerosol generation and increased risk of transmission (from patients with a known or suspected respiratory infection). Aerosol generating procedures (AGPs)Ī medical procedure that can result in the release of aerosols from the respiratory tract. A minor wound in which the surface of the skin or a mucous membrane has been worn away by rubbing or scraping. ![]()
