What is the simple definition of infiltration?
Infiltration is a term used to describe a process where one thing passes into another. It is a term used most often when referring to water or a liquid, when it permeates an object or substance by entering into gaps or pores.
What is an example of infiltrate?
a : to secretly enter or join (something, such as a group or an organization) in order to get information or do harm. The gang was infiltrated by undercover agents.
What causes infiltrate?
Diffuse early infiltrates might be caused by leukemic infiltration of the lungs, pulmonary hemorrhage and/or edema, diffuse alveolar damage, viral pneumonia, and rarely transfusion-related acute lung injury (TRALI) or the differentiation syndrome.
What is an infiltrative process?
A process whereby inflammatory or other types of disease spread throughout an organ such as the lungs.
What happens during infiltration?
Infiltration refers to the process where precipitation or water infuses into subsurface soils, is absorbed by the soil and travels deeper through pore spaces and cracks into rocks. The bulk of water collected from melted snow and rain end up infiltrated.
What are the types of infiltration?
Common infiltration practices include drywells, bioretention, permeable pavement, infiltration trenches, infiltration basins, and subsurface infiltration galleries. Regardless of their form, all infiltration systems have three primary components: storage, treatment, and infiltration.
What does infiltrate mean on chest xray?
When interpreting the x-ray, the radiologist will look for white spots in the lungs (called infiltrates) that identify an infection. This exam will also help determine if you have any complications related to pneumonia such as abscesses or pleural effusions (fluid surrounding the lungs).
What can cause infiltrates in lungs?
Pulmonary infiltrates commonly occur in the febrile neutropenic patient and have a number of causes, especially in the BMT recipient. These include non-infective conditions such as pulmonary edema, alveolar hemorrhage, adverse drug reactions, radiation injury and the idiopathic pneumonitis syndrome.
Does infiltrate always mean pneumonia?
Pneumonia Can Often Be Seen on a Chest X-ray.
A chest x-ray in a person with pneumonia does not always have the characteristic “infiltrate” early in the course of the illness.
Are infiltrates the same as pneumonia?
A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. Pulmonary infiltrates are associated with pneumonia, tuberculosis, and sarcoidosis. Pulmonary infiltrates can be observed on a chest radiograph.
What does soft tissue infiltration mean?
FAMILY MEDICINE. Identification and description of the procedure. Soft tissue infiltration consists of inserted an anti-inflammatory substance (usually a corticoid generally with an anaesthetic) near a tendon or tendon bursa.
What is organ infiltration?
Definition. A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease. All types of leukemia show various degrees of infiltration, depending upon the type of leukemia. The degree of infiltration may vary from site to site.
How do you fix an infiltrated IV?
Some possible treatments are: Elevate the site as much as possible to help reduce swelling. Apply a warm or cold compress (depending on the fluid) for 30 minutes every 2-3 hours to help reduce swelling and discomfort. Medication-If recommended, medicine for extravasations is given within 24 hours for best effect.
Where does infiltration occur?
Infiltration and inflow (I/I) is excess water that flows into sewer pipes from groundwater and stormwater. Groundwater (infiltration) seeps into sewer pipes through holes, cracks, joint failures, and faulty connections.
What are the 7 factors that affect infiltration?
Factors affecting Infiltration
- Precipitation level.
- Soil Characteristics.
- Vegetative cover.
- Slope of land.
- Soil saturation.
- Evapotranspiration level.
- Human activities.
What does infiltrates in lungs mean?
How do you treat lung infiltrates?
Studies estimate that for ICU patients with pulmonary infiltrates 70%-80% do not have pneumonia, but currently most will receive combination broad spectrum empiric antibiotic therapy with duration from 5-14 days.
Do lung infiltrates go away?
Radiographic lung infiltrates resulting from acute pneumonia usually resolve within 1-3 wk, but a substantial number of children, particularly infants, fail to completely clear infiltrates within a 4 wk period.
Can a benign tumor infiltrate?
Benign tumors grow only in one place. They cannot spread or invade other parts of your body.
What is malignant infiltrate?
Cancer that has spread beyond the layer of tissue in which it developed and is growing into surrounding, healthy tissues.
What is infiltration in tissue?
Infiltration is the diffusion or accumulation (in a tissue or cells) of foreign substances in amounts excess of the normal. The material collected in those tissues or cells is called infiltrate.
What are leukemic infiltrates?
Definition. A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease.
What happens when IV infiltrates?
An infiltrated IV (intravenous) catheter happens when the catheter goes through or comes out of your vein. The IV fluid then leaks into the surrounding tissue. This may cause pain, swelling, and skin that is cool to the touch.
Can IV infiltration cause blood clot?
Superficial thrombophlebitis is an inflammation of a vein just below the surface of the skin, which results from a blood clot. This condition may occur after recently using an IV line, or after trauma to the vein. Some symptoms can include pain and tenderness along the vein and hardening and feeling cord-like.
What is the effect of infiltration?
For a given depth of cumulative infiltration, a higher rate of infiltration creates higher subsurface flux (for a shorter duration), which exacerbates the pressure head increase at the hydraulic conductivity contrast at the embankment’s upslope boundary.
