OBJECTIVES Venovenous extracorporeal gas exchange is increasingly used in awake, spontaneously breathing patients as a bridge to lung transplantation. Limited data are available on a similar use of extracorporeal gas exchange in patients with acute respiratory distress syndrome. The aim of this study was to investigate the use of extracorporeal gas exchange in awake, spontaneously breathing she...

Gas exchange is improved during partial liquid ventilation with perfluorocarbon in animal models of acute lung injury. The specific mechanisms are unproved. We measured end-expiratory lung volume (EELV) by null-point body plethysmography in anesthetized sheep. Measurements of gas exchange and EELV were made before and after acute lung injury was induced with intravenous oleic acid to decrease E...

Measuring soluble gas in the exhaled breath is a non-invasive technique used to estimate levels of respiratory, solvent, and metabolic gases. The interpretation of these measurements is based on the assumption that the measured gases exchange in the alveoli. While the respiratory gases have a low blood-solubility and exchange in the alveoli, high blood-soluble gases exchange in the airways. The...

in order to investigate effect of organic manure and super absorbent on physiological and biochemical traits of potato (solanum tubersum, cv marfona), a split plot experiment was conducted as randomized complete block design with three replications at research farm, agriculture college, university of razi in 2010. main factor included two levels of super absorbent a200 (0 and 70 kg/ha,) and spl...

Few commercial genotypes of tomato are resistant to Fusarium wilt (Fusarium oxysporum f. sp. lycopersici [FOL]), especially race 3. We developed five intraspecific hybrids Solanum lycopersicum (FOX1 FOX5) and assessed them for agronomic traits resistance FOL races 1, 2, 3, a mixture these races. FOX1 FOX4 were all the but did not have desired traits. Next, as rootstocks cherry Sweet Heaven. The...

The influence of diaphragmatic position on abnormal gas exchange has been examined to investigate the theory that the impairment in gas exchange in anaesthetized man is caused by disturbance of diaphragmatic mechanics, resulting in abnormalities of dependent lung ventilation. A gas exchange abnormality, probably caused by airway closure in the dependent regions of the lung, was induced in anaes...
