A composite semiclosed anaesthetic system suitable for controlled or spontaneous respiration.
FOR patients who are breathing spontaneously the Magill attachment or system A (Mapleson, 1954) is the most widely used semiclosed anaesthetic system. A theoretical analysis predicted that if the freshgas inflow were made at least equal to the patient's minute-volume ventilation, then rebreathing would be eliminated (Mapleson, 1954). A similar conclusion has been reached experimentally by vario...
متن کاملControlled ventilation or spontaneous respiration in anesthesia for tracheobronchial foreign body removal: a meta-analysis.
BACKGROUND Either controlled ventilation or spontaneous respiration is commonly used in general anesthesia for inhaled foreign body removal via rigid bronchoscopy. Controversy in the literature exists concerning which form of ventilation is optimally suited for bronchoscopy. We performed a meta-analysis to compare controlled ventilation and spontaneous respiration with respect to complications,...
متن کاملSpontaneous ventilation with the Bain anaesthetic system.
Measurements of ventilation and of inspired gas composition were made while volunteers breathed a non-anaesthetic gas through a Bain anaesthetic system. It was found that rebreathing occurred when the fresh gas flow was between two-and-a-half and three times the minute volume. Fresh gas flows at least three times the minute volume appear to be necessary to prevent rebreathing when using this sy...
متن کاملA microprocessor-controlled anaesthetic vaporizer.
A microprocessor-controlled anaesthetic vaporizer is described. Fresh gas is mixed in the correct proportions using two pulsed solenoid valves and a proportion of this passes through a third pulsed solenoid valve and is bubbled through liquid halothane. The temperature of the liquid agent is measured and the pulse frequency is modified to give the correct vapour concentration for the set flow r...
متن کاملPositive pressure ventilation using a semiclosed system: a reassessment.
The use of a semidosed system (the Magill attachment) for positive pressure breathing was investigated. Various patterns of ventilation were used and their effects assessed by serial measurement of the arterial carbon dioxide. It was found that this could be kept within limits comparable to those found during normal sleep using a flow of fresh gases as low as 5 l./min. This result was most easi...
