Modeling oxygen transport in surgical tissue transfer.
Reconstructive microsurgery is a clinical technique used to transfer large amounts of a patient's tissue from one location used to another in order to restore physical deformities caused by trauma, tumors, or congenital abnormalities. The trend in this field is to transfer tissue using increasingly smaller blood vessels, which decreases problems associated with tissue harvest but increases the ...
متن کاملABC of oxygen Oxygen transport—2. Tissue hypoxia
Delivery to organs and tissues The mechanisms controlling oxygen distribution are incompletely understood but involve a series of convective and diffusive processes. Convective oxygen transport refers to the bulk movement of oxygen in air or blood and depends on active, energy consuming processes generating flow in the tracheobronchial tree and circulation. Diffusive transport refers to the pas...
متن کاملNonsteady state oxygen transport in engineered tissue: implications for design.
Engineered tissue constructs are limited in size, and thus clinical relevance, when diffusion is the primary mode of oxygen transport. Understanding the extent of oxygen diffusion and cellular consumption is necessary for the design of engineered tissues, particularly those intended for implantation into hypoxic wound sites. This study presents a combined experimental and computation model to p...
متن کاملDimensional analysis for modeling oxygen transfer in rotating biological contactor.
In rotating biological contactors (RBC), the oxygen mass transfer coefficient (KLa) is often inadequately predicted by the available models. Hence, dimensional analysis based empirical models were developed for predicting KLa and the component of KLa due to turbulence (KLat) using data available in the literature. The overall oxygen transfer number (OTN) and its component due to turbulence (OTN...
متن کاملGEP Modeling of Oxygen Transfer Efficiency Prediction in Aeration Cascades
Artificial intelligence is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. In the past few years, the applications of artificial intelligence methods have attracted the attention of many investigators. Many artificial intelligence methods have been applied in various areas of civil and environmental engineering. The aim o...
