Rebreathing with a Semi-closed System by Ronald Woolmer and Bj0rn Lind
THE completeness of carbon dioxide elimination during inhalation anaesthesia is important; and it is generally agreed that it is undesirable to allow the alveolar carbon dioxide to deviate much from normal. draws the sample at a steady rate from the gases flowing past the end of the bleeder tube. But these gases do not flow at a steady rate throughout the phase under examination. Their velocity...
متن کاملEffect of Charcoal Filter on the Emergence from Sevoflurane Anesthesia in a Semi-Closed Rebreathing Circuit
PURPOSE A charcoal filter attached within the anesthetic circuit has been shown to efficiently adsorb halothane or isoflurane, thus hastening anesthetic recovery in low or minimal flow system. This study was intended to demonstrate whether the charcoal filter enhances the recovery time from sevoflurane anesthesia using a semi-closed circuit system. MATERIALS AND METHODS Thirty healthy patient...
متن کاملAlveolar gas relationships during the use of semi-closed rebreathing anaesthetic systems.
A black box and a geometrical approach have been used to deduce the relationships between alveolar oxygen and carbon dioxide concentrations when rebreathing occurs during the use of semi-closed anaesthetic rebreathing systems.
متن کاملClosed-loop force control for a semi-automatic grinding system
Automation of grinding of metalcastings is desirable for many reasons. The major reasons are dangerous working conditions, low productivity, and inconsistency in human operations. As an approach to the automating grinding process, a gantrydriven grinding machine is proposed to manipulate an industrial hand grinder and control the grinding force applied to the work piece. To increase the materia...
متن کاملCALCULATION OF OSMOTIC PRESSURE USING A CLOSED SYSTEM MODEL
In this work we have used a closed system model to derive an analytical equation for the osmotic pressure of two component electrolyte and non-electrolyte solutions. In order to do so, we have used an equation of state, known as the dense system equation of state (DSEOS), for the model system. Based on the model, a new definition is given for the osmotic pressure of a closed system. Good ag...
