  • permeability
  • The various mechanisms believed to be responsible are pulmonary arterial vasoconstriction resulting in circulatory shear forces and a consequent permeability leak and antidiuresis possibly mediated by increased antidiuretic hormones, which contribute to fluid retention. (medscape.com)
  • Bronchoalveolar lavage fluid (BALF) studies have shown that after heavy exercise, under all conditions, athletes develop a permeability edema with high BALF RBC and protein concentrations in the absence of inflammation. (medscape.com)
  • Activation of sensory nerves in rodent airways results in microvascular permeability and edema formation, presumably due to release of vasoactive neuropeptides from the nerve endings. (uptodate.com)
  • The latter, noncardiogenic pulmonary edema (NPE), is caused by changes in permeability of the pulmonary capillary membrane as a result of either a direct or an indirect pathologic insult (see the images below). (medscape.com)
  • The authors investigated the relative abilities of various opioids to induce histamine release mediated increased capillary permeability and tissue edema ("wheal response" ) and cutaneous vasodilatation and local redness ("flare response") when subjects were intradermally injected with 0.02 ml equimolar concentrations of 5 x 10-4 M. Nalbuphine did not produce either a wheal or flare response. (wikipedia.org)
  • severe
  • Although CPE is usually associated with hypocapnia, hypercapnia with respiratory acidosis may be seen in patients with severe CPE or underlying chronic obstructive pulmonary disease (COPD). (medscape.com)
  • peripheral edema
  • this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body and includes peripheral edema (swelling of the legs, in general, of the "pitting" variety, wherein the skin is slow to return to normal when pressed upon), raised jugular venous pressure and hepatomegaly , where the liver is enlarged and may be tender or even pulsatile. (wikipedia.org)
  • Patients with concurrent right ventricular (RV) failure may present with hepatomegaly, hepatojugular reflux, and peripheral edema. (medscape.com)
