A theoretical study of gaseous homeostasis in the Magill circuit.
Equations have been derived to determine the alveolar gas concentrations which occur when the Magill (Mapleson A) circuit is used with a low fresh gas flow. Alveolar oxygen and carbon dioxide concentrations are determined by the fresh gas flow and composition, carbon dioxide output and oxygen uptake. Gas mixing within the circuit and alterations in the inspired gas concentrations do not affect ...

A study of carbon dioxide tensions during halothane anaesthesia using the Magill circuit.
In thirteen patients capillary blood samples were obtained for measurement of pH and Pcoa immediately after the induction dose of thiopentone, after 45 minutes of 2 per cent halothane breathed spontaneously (with nitrous oxide and oxygen), and 30 minutes postoperatively. A very variable rise in Pco2 was observed which did not correlate well with changes in pulse rate, blood pressure, respirator...
متن کاملEquivalent Circuit Modification for Organic Solar Cells
In this work, a newly fabricated organic solar cell based on a composite of fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and regioregular poly (3-hexylthiophene) (P3HT) with an added interfacial layer of AgOx in between the PEDOT:PSS layer and the ITO layer is investigated and an equivalent circuit model is proposed for the device. Incorporation of the AgOx interfacial...
متن کاملa New Resonant Converter Circuit for Reluctance
The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.
