The purpose of this investigation was to measure and compare the resistances to steady gas flows, and to the varying gas flows occurring during normal respiration, of some commonly used anaesthetic apparatus. A preliminary study of the pressure-flow characteristics of semiclosed anaesthetic breathing systems has also been made. The items of equipment investigated were: a Magill attachment consisting of a reservoir bag, a corrugated rubber tube with its end fitting and a Heidbrink expiratory valve; an endotracheal catheter mount; a No. 4 Cobb suction union; a No. 9 curved Magill endotracheal connector*; a No. 10 endotracheal tube and a Coxeter expira-tory valve. These items were considered individu-ally, connected together and assembled to f...
