A new valve for draw-over anaesthesia.
The Diamedica non-rebreathing valve has been developed for use in draw-over anaesthesia and can be positioned at the common gas outlet. Its performance was evaluated against the Laerdal, Ruben and Ambu valves under laboratory conditions. Valve resistance during inspiration and expiration was simulated over a range of constant flow conditions. During flows ranging from 5 to 45 l.min(-1) , the Di...
متن کاملModification of a draw-over vaporizer for use with sevoflurane.
BACKGROUND Draw-over anaesthesia is widely used throughout the developing world, in disaster areas and in military anaesthesia when the supply of pressurized oxygen is unreliable. To date, no draw-over vaporizer has been able to deliver sufficient concentrations of sevoflurane for use in inhalation induction of anaesthesia. A laboratory study to assess the performance of a new vaporizer (DDV2) ...
متن کاملGame Over: Black to Play and Draw in Checkers
In 1989, an effort to solve the game of checkers began. It was naïve because of the daunting size of the search space, 5×10 positions, and because of computer capabilities of the time. Nevertheless the work continued, with the final calculation completing in 2007. The result? Perfect play by both sides leads to a draw. Checkers is the largest popular game that has been solved to date.
متن کاملSevoflurane Output in the Isoflurane/Halothane Diamedica Draw-over Vaporiser.
INTRODUCTION Draw-over anaesthesia remains an attractive option for conduct of anaesthesia in austere conditions. The Diamedica Draw-over Vaporiser (DDV) is a modern draw-over vaporiser and has separate models for isoflurane/halothane and sevoflurane. MATERIALS AND METHODS A laboratory study was done to measure sevoflurane output in an isoflurane/ halothane DDV. We did 3 series of experiments...
متن کاملVentilatory effects of isoflurane: a comparison with halothane in a draw-over system.
Halothane and isoflurane were studied using a draw-over anaesthetic system in two groups each of 25 patients to compare the ventilatory effects of the two agents in field anaesthesia. Respiratory variables were measured and it was confirmed that isoflurane is a more potent respiratory depressant than halothane, but satisfactory anaesthesia for short procedures was possible.
