The Dumping Valve and its Clinical Application
An open reservoir for the collection and evacuation of anaesthetic gases permits leakage to room air. The use of a closed reservoir for the removal of overspill gas from anaesthetic circuits is described. Calibrated gas evacuation is carried out through an ejector flowmeter from the anaesthetic circuit or from a closed reservoir, where the gas is collected via a relief valve. In order to eliminate the risk of high or low pressure in the reservoir employed, a relief valve and a dumping valve is included in the system.
Søren Jørgensen On the Occasion of his 60th Birthday
Ssren <Jsrgensen was born on the 17th November, 1920 in Aarhus (parents: organist Robert Jsrgensen and Mariane E. K.

He was a member of the Ministry of Health’s Anaesthesiology Committee for the Evaluation of Qualifications in 197078 and a member of the Society of Anaesthesiologists’ Education Committee in 1970-76. He was also a board member of the Scandinavian Society of Anaesthesiologists in 1962-75, vicepresident in 1975-77, and president in 1977-79.

He was made a Knight of the Order of the Dannebrog in 1978, and chairman of the stipendiary committee of the Medical Faculty, Odense University in 1980.
Risk of Contamination from the Anesthesia Circle Absorber: An Evaluation
URING the past several years there has D been sporadic concern about the possible contamination hazards from anesthesia machines and equipment. Bacterial infection of the patient from anesthesia equipment in our hospital was first seriously considered when our open-heart patients developed pulmonary infections postoperatively. No direct correlation was established. However, repeated culture studies of our anesthesia circle absorbers and rubber parts revealed many badefia types, some of which were pathogens. Attempts to clean the circle-absorber system presented many problems, including unreliable and messy cleansing agents, difficulty in removing mechanical parts, heat-labile materials, and toxic effects of sterilizing agents.
