Abstract: A feasibility study was conducted for the design of a hollow fibre carbon dioxideremoval device for use within anaesthesia. It is proposed that the device will beused to replace current carbon dioxide capture methods, which pose issues in bothpatient safety and environmental aspects. Experimental studies were undertakenwhereby the pressure drop of respiratory gases, that are, carbon dioxide, oxygenand nitrogen, and select anaesthetic gases, sevoflurane, isoflurane and halothane,were measured over time in order to assess the diffusivity and permeability of eachgas through a selectively permeable block co-polymer membrane, Arnitel VT3108.By use of data collected through experimentation and computational modelling, afeasible preliminary device design was suggested with geometries of approximately0.14m in length and 0.2m in diameter, based upon a device with 50000 hollow fibresof 350m outer radius and 25m wall thickness. A proposed design for the diffusivedevice is shown in Figure 1.
