Prevention of hazardous pollution in hospital operating theatres with the use of mechanical systems.

This article describes, with the aid of sketches, the mechanical systems which could economically be designed for hospital operating theatres in an endeavour to eliminate the effects of hazardous pollution which exists in the majority of operating theatres. This article describes two seperate systems to combat the two major sources of pollution in operating theatres - contaminated air which reaches the operative wound of the patient, and the hazardous anaesthetic gases which are released into the atmosphere of operating theatres and associated areas such as recovery rooms.
