Asepsis Flashcards
the use of practices aimed at destroying pathological organisms after they leave the body
Medical Asepsis
employed in the care of patients with infectious diseases to prevent reinfection of the patient and to avoid the spread of infection from one person to another.
Medical Asepsis
The maintenance of strict disinfection procedures or antisepsis and infection control practices during an operation.
Surgical Asepsis
Sterile technique
Surgical Asepsis
free from infection or germs; absence of disease producing microorganisms; prevention of contact with microorganisms; following practices that prevent or break the chain of infection
Asepsis
ability for an organism to cause infection depends on…
- number of organisms
- virulence
- function of immune system
- duration of contact
- type of contact
4 types of disease transmission
Direct, Indirect, Airborne, Droplet
occurs when there is physical contact between an infected person
and a susceptible person.
Direct Disease Transmission
occurs when there is no direct human-to-human contact. Contact
occurs from a reservoir to contaminated surfaces or objects, or to vectors such as mosquitoes,
flies, mites, fleas, ticks, rodents or dogs.
Indirect Disease Transmission
occurs when bacteria or viruses travel on dust particles or on small respiratory droplets that may become aerosolized when people sneeze, cough, laugh, or exhale. They hang in the air much like invisible smoke. They can travel on air currents over considerable distances.
Airborne Disease Transmission
occurs when oral or nasal secretions infected with an illness enter the eyes, nose or mouth of another person. The secretions are most commonly passed through coughing or sneezing; this is the way the flu and many viruses are spread.
Droplet Disease Transmission
indirect transmission of an infectious agent that occurs when an inanimate object touches a person’s body or is ingested
