Difficult Ventilation in a patient after Endotracheal Intubation: an Unusual Manufacturing Defect in E.T.T. Connecter

Abstract

Summary: Airway resistance depends upon the diameter of endotracheal tube (E.T.T) and other respiratory organs. Actually resistance to flow through a tube increases up to sixteen times if diameter is reduced to half of the original size. Disposable E.T.T which are currently used in anaesthesia practice are made up of P.V.C with a connecter which is fitted on proximal end of endotracheal tube and proximal end of connector I attached with breathing circuit. Usually the internal diameter of connector should be equal to internal diameter of endotracheal tube.
