The potential transmission of disease by anaesthetic and ventilator breathing circuits has resulted in the widespread use of filters. Convincing scientific evidence of their complete efficacy is lacking particularly in regard to viruses. In the past, practical difficulties precluded the use of new or autoclavable equipment for successive patients, particularly if ventilators were required. These have been overcome by the development of disposable and autoclavable carbon dioxide absorbers and breathing circuits. Disposable equipment is more expensive than filters but autoclavable circuits and absorbers are of comparable cost or cheaper.

Seven per cent of deaths resulting from motor car accidents are due to asphyxia without any other major injury. This highlights the importance of maintaining an unobstructed airway in patients following motor vehicle accidents. These cases of asphyxia are due to laryngeal spasm, aspirated foreign material, or pharyngeal obstruction by the tongue in a semi-conscious or unconscious patient. It is reasonable to assume that many of these lives could be saved by simple techniques, such as removing foreign material from the pharynx, pulling the chin and head back firmly, and turning the patient into the lateral position.
