Thesis (MScEng)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Patients in critical care with lung injuries need to be assisted with regards to breathing function, but current methods are not applicable for all situations. The most common method, Extracorporeal Membrane Oxygenation (ECMO) is an expensive procedure and requires trained staff to operate the equipment at all times. Lung injury may lead to the inability of the lungs to be perfused and the blood oxygenated by tracheal intubation, whereas mechanical ventilators can injure the lungs further. Especially at risk are preterm neona

Abstract:
The effects of oxygenation and aeration on water quality, rainbow trout (Oncorhynchus mykiss) production, and economics were compared at the Wytheville State Fish Hatchery (WSFH) for 270 days. Mean dissolved oxygen (DO) concentrations and delta DO were significantly higher (P < 0.001) in the oxygenated raceways (9.5 and 2.75 mg/L, respectively) compared to aerated raceways (7.4 and 0.57 mg/L). Total settleable solids loads were significantly greater (P < 0.001) in aerated raceways (10.3 g/L/day) than in oxygenated raceways (8.8 g/L/day).

Abstract:
Previous intravenous oxygenators relied on 02 diffusion to treat Acute Respiratory Distress Syndrome. However, bubble oxygenators may increase 02 transfer. Polypropylene and polysulfone hollow fiber membranes were modified using vapor graft polymerization (VGP) and solution graft polymerization (SGP) to decrease the pore size and porosity and increase the hydrophilicity of the fibers so that as 02 flowed through the treated fibers submerged in water the bubbles formed from the treated fiber would be smaller than those from pure fibers. Both methods increased the surface hydrophilicity; however

Abstract:
Over 26 million Americans suffer from pulmonary disease, resulting in more than 150,000 deaths annually. Lung transplantation remains the only definitive treatment for many patients, but has meager survival rates and only approximately 1,700 of the 2,200 patients added to the lung transplant wait list each year are transplanted. Extracorporeal gas exchangers have been used as an alternative to mechanical ventilation in acute respiratory failure and as a bridge to transplantation in chronic respiratory failure. Current gas exchangers are limited by their high resistance and low biocompatibility
