StandardsLow-Flow Pollution-Free Dental Anaesthesia
High fresh gas flows and theatre pollution around the mouth can be much reduced by use of the Humphrey ADE system.
The lightweight ADE tubing can be connected directly to the dental mask as shown in the diagram.
Low FGFs of only 3-4 l/min are required. Expired gases are scavenged at the exhaust valve and are not allowed to escape at the valve on the mask which is closed.
