A valve substitute with no moving parts, for artificial ventilation in newborn and small infants

Abstract

Summary: An anaesthetic system incorporating the principle of kinetic energy of gas flow has been developed for use during intermittent positive pressure respiration in paediatric anaesthesia. The advantages of the system are that it has no moving parts, is of small bulk and has minimum deadspace and resistance to respiration. The major disadvantage of the system is the large gas flows required particularly in the presence of a low compliance or a small endotracheal tube. The system has been used during anaesthesia and in three cases who required prolonged mechanical ventilation. © 1968 John Sherratt and Son Ltd.
