Abstract:
:A new anaesthetic gas scavenging system is described. The resistance of the system appears to be low. When input gas flow rate in the system was zero or 150 litre min-1, misuse of the system produced pressure changes at its collecting points of 26 Pa subatmospheric and 630 Pa above atmospheric pressure, respectively. Suggestions to develop the system and increase its safety are presented.
