The humidification of anaesthetic gases: its importance and control.
THiS REV,EW studies the humidi ty output of anaesthet ic sys tems in common use and the steps taken to improve them. The amount of water vapour which an a tmosphere can hold varies with temperature . The warmer the ambient gas mixture, the more water vapour it can contain. There is a max imum amount of water vapour which the a tmosphere can maintain at each tempera ture when it becomes saturate...
متن کاملMembrane humidification--a new method for humidification of respiratory gases in ventilator treatment of neonates.
A humidifier system for neonatology that functions according to the 'membrane humidification' principle was subjected to a performance test in our laboratory. Humidification and heating of the respiratory gases took place in a module consisting of a net of hollow fibres placed inside the incubator. In 18 measurement combinations flow, respiratory gas temperature, and incubator temperature were ...
متن کاملInhaled gases humidification and heating during artificial ventilation with low flow and minimal fresh gases flow.
BACKGROUND AND OBJECTIVES Inhaled gas humidification and heating are necessary in patients under tracheal intubation or tracheostomy to prevent damage to respiratory system resulting from the contact of cold and dry gas with the airways. This study aimed at evaluating the effect of respiratory circle systems with carbon dioxide absorbers from Dräger's Cicero anesthesia machine (Germany) as to i...
متن کاملEffects of trace anaesthetic gases on behavioural performance of volunteers.
Nitrous oxide and halothane, in concentrations as low as 50 p.p.m. and 1.0 p.p.m. respectively, caused measurable decrements in performance in psychological tests in healthy male volunteers. Nitrous oxide alone caused similar effects. The functions apparently most sensitive to these low concentrations of anaesthetic agents were visual perception, immediate memory, and a combination of perceptio...
متن کاملScavenging of anaesthetic gases using the double T-piece system.
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 ...
