Infiltration Leakage

The airflow rate infiltrating and exfiltrating through each air leakage pass, Q , due to the combined effect of wind, stack, and mechanical ventilation system perfotmance can be calculated ftom the mass balance equation... [Pg.582]

Infiltration The leakage of air through the imperfections in a building structure, due to thermal or wind forces. [Pg.1451]

Inspect die needle site and surrounding tissues at frequent intervals for leakage (extravasation, infiltration) of die solution into die subcutaneous tissues surrounding die needle site If eitiier situation occurs, establish anotiier IV line immediately, discontinue the IV containing the vasopressor, and... [Pg.206]

Observe the IV site closely to detect any signs of extravasation (leakage into the surrounding tissues). Tissue necrosis can be a serious complication. Discontinue the infusion and notify the primary health care provider if disoomfort, redness along the pathway of the vein, or infiltration occurs. [Pg.597]

Superoxide dismutases (SODs) are a family of cytosolic metalloenzymes that specifically remove (reviewed by Omar etal., 1992). SOD distribution within the body is ubiquitous, being found in erythrocytes as well as most organs and cell types. Three distinct mammalian SOD forms exist CuZnSOD, MnSOD and extracellular SOD (EC-SOD). Their amino-acid sequences differ as well as the transition metals at their active sites. Rheumatoid synovial fluid contains low levels of SOD activity and hence little protection from ROM generated by infiltrating PMNs (Blake etcU., 1981). Furthermore, leucocytes from patients with RA are deficient in MnSOD, which might promote the extracellular leakage of O2 (Pasquier et al., 1984). [Pg.100]

Extravasation Movement of fluid from inside a blood vessel into the surrounding tissues for example, leakage or infiltration of a vesicant chemotherapy agent into local tissue. [Pg.1566]

A higher than expected gain or loss of fuel in a tank may be caused by water infiltration or leakage of fuel through the tank wall. [Pg.692]

Smoke infiltration may result from natural leakage openings (e.g., around ventilation ducting/grills), open doors, or breached fire barriers. The integrity of... [Pg.82]

Local necrosis may occur following perivenous leakage of thiopentone. As median nerve damage has been reported following extravasation in the antecubital fossa, this site is not recommended for administration of thiopentone. If significant extravasation occurs then hyaluronidase should be infiltrated into the affected area to facilitate reabsorption. [Pg.81]

The pathophysiology of IR injury in the lung involves increased leakage from the pulmonary microvasculature leading to interstitial and alveolar edema, excessive infiltration of polymorphonuclear cells into the lung, tissue inflammation, and apoptosis (de Perrot et al. 2003). [Pg.215]

The acute inflammatory response (see Table 14.1) leads to inflammation, redness, swelling, heat and pain, due to extravasation (leakage) of plasma and infiltration of leukocytes into the site of inflammation. Mechanisms that allow cells and proteins to gain access to damaged or infected extravascular sites include ... [Pg.211]

Erythema is the most common effect of UVR exposure. The exact mechanism of how UVR induces skin erythema is not fully understood however, it is believed that a number of mediators are involved in the inflammatory reaction (260). These include histamine, lysosomal enzymes, kinins, and at least one prostaglandin. These mediators produce vasodilatation, which is manifested in erythema. As the UV radiation penetrates into the epidermis, another inflammatory reaction involving a lymphocytic infiltrate develops. Swelling of the endothelium and leakage of red blood cells also occurs. The inflammatory effect of UVB radiation reaches its maximum in 12-24 h after exposure (260). [Pg.464]
