pulmonary pleura
| extracorporeal dialysis | Haemodialysis performed through an apparatus outside the body. (05 Mar 2000) |
|---|---|
| acid perfusion test | <gastroenterology, investigation> A test used to diagnosis gastrooesophageal reflux disease. This investigation requires that the patient swallow 3 tiny tubes into the stomach. A mixture of hydrochloric acid (like stomach acid) and saline are alternatively injected into the tubes. The patient then reports any symptoms they may have. Some patients may vomit. (13 Nov 1997) |
| arterial perfusion | <procedure> Treatment in which blood is drawn from a patient, pumped through a machine that adds anticancer drugs and returned to the major artery supplying the limb being treated. (16 Dec 1997) |
| ventilation/perfusion lung imaging | <radiology> See: ventilation agents, perfusion agents, Biello-Siegel criteria (12 Dec 1998) |
| ventilation/perfusion mismatch | An imbalance between alveolar ventilation and pulmonary capillary blood flow. (05 Mar 2000) |
| ventilation-perfusion ratio | The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung. (12 Dec 1998) |
| ventilation/perfusion ratio | The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung; because both ventilation and perfusion are expressed per unit volume of tissue and per unit time, which cancel, the units become liters of gas per liter of blood. (05 Mar 2000) |
| ventilation-perfusion scan | A lung function test, especially useful for pulmonary embolism, employing an inhaled radionuclide for ventilation and an intravenous radionuclide for perfusion; their respective distributions in the lung are recorded scintigraphically. (05 Mar 2000) |
| ventilation perfusion scanning | <investigation, radiology> A nuclear medicine test that involves the inhalation of a radioactive gas and the injection of a radioactive compound into the bloodstream. A special camera measures the radioactive compound and generates a image of the lungs. Comparisons are made between the images generated. Pulmonary embolism can be diagnosed using this procedure. (12 Jan 1998) |
| perfusion | 1. <physiology> The act of pouring over or through, especially the passage of a fluid through the vessels of a specific organ. 2. A liquid poured over or through an organ or tissue. (18 Nov 1997) |
| perfusion cannula | A double-barreled cannula used for irrigation of a cavity, the wash fluid passing into the cavity through one tube and out through the other. Washout cannula, a cannula that can be irrigated without removal from the artery. (05 Mar 2000) |
| perfusion, regional | Neoplasm drug therapy involving an extracorporeal circuit with temporary exclusion of the tumour-bearing area from the general circulation during which high concentrations of the drug are perfused to the isolated part. (12 Dec 1998) |
| coronary perfusion pressure | The pressure at which blood proceeds through the coronary circulation, mainly in diastole. (05 Mar 2000) |
| myocardial perfusion imaging | <radiology> (thallium scanning) thallium (Tl) 201, acts as potassium analog, dose 2.0 - 3.0 mCi at peak exercise, 4% of injected dose reaches myocardium, imaging: exercise (1-5 min), redistribution (3-4 hrs), views: anterior, LAO 45', left lateral, interpretation: normal, reversible abnormalitymost likely to be exercise-induced ischemia, nonreversible abnormalitymost likely to be prior myocardial infarction, reverse redistribution most likely to be normal areas wash out faster, lung activity most likely to be LV failure during exercise see also: dipyridamole test, nuclear cardiology (12 Dec 1998) |
| isolated limb perfusion | <oncology, procedure> Chemotherapy treatment in which blood is taken from a patient, pumped through a machine that adds anticancer drugs to the blood, then returned to the limb being treated. (15 Oct 1997) |
