[The removal of anaesthetic vapours using t-piece circuits in paediatric anaesthesia (author's transl)]. 1976

J Wawersik

In order to remove exhaled vapours from T-piece circuits, a rebreathing bag with an additional outlet (double ended bag) may be used. The narrow end of the bag is connected to a circle closed circuit with a filter incorporated in the expiratory side. So T-piece technique remains convenient. A small increase of expiratory resistance of about 1.5-2.5 ml H2O does not change spontaneous ventilation, compared with commonly used semi-closed breathing circuits in pediatric anaesthesia. Assisted or controlled ventilation may be performed, adjusting the expiratory valve at the circle closed system.

D005740	Gases	The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure.
