A simple T-piece.
THE value of the T-piece principle in reducing the resistance an anaesthetic apparatus offers to respiration is well established. Unfortunately the commonly used Ayre's (1937) T-piece cannot be connected directly to the endotracheal tube. The angled connectors and pieces of rubber tubing which must be interposed markedly increase the resistance of the apparatus to respiration. To overcome this ...

Ayre's T-piece. The Ayre's T-piece (Ayre, 1937) has a very low resistance, is simple, and almost trouble-free. Intermittent positive pressure respiration (IPPR) can be induced by occluding the exhalation reservoir tube intermittently with one finger. However, the pressure, volume, and riming of lung inflation depends on the flow of gases from the anaesthetic machine and the duration of finger o...

Background & Aims : Because for the known complications of prolonged mechanical ventilation, weaning from mechanical ventilation (MV) is very important. We aimed to determine the outcome of two conventional weaning types and comparison of those in patients receiving MV. Materials & Methods : During an 8 month period we enrolled all patients admitted to intensive care departments who receive...

fully expected but it is inappropriate, for the following reasons: Considerably less halothane is given when a caudal block is performed than during a general anaesthetic alone. After the blocking procedure, just sufficient general anaesthetic was given to prevent the child from disturbing the surgeon. For this purpose nitrous oxide in oxygen was sufficient in the majority of patients. It does ...
متن کاملRebreathing in a T-piece: volunteer and theoretical studies of the Jackson-Rees modification of Ayre's T-piece during spontaneous respiration.
The Jackson-Rees modification of Ayre's T-piece was examined experimentally and theoretically to see what effects the theoretical restrictions of Onchi, Hayashi and Ueyama (1957) (1:1 I:E ratio, zero deadspace volume) and the square-wave approximation of Mapleson (1958) may have had on the calculated critical fresh-gas flow rate necessary to prevent rebreathing of exhaled alveolar gases. In the...
