Abstract
Pollution control should be simple, cheap and effective. It should not introduce further hazards to the patient nor significantly complicate the practice of anaesthesia. These goals are attainable using a simple passive system. Convenience in use is enhanced by a concentric tubing system which allows effluent gases to be collected at the machine end and exhausted to the exterior. The additional expiratory resistance is minimal.
