StandardsPollution Control
Pollution has become more important as recognition of its detrimental effects on the theatre environment is acknowledged. In the UK, COSH regulations are now mandatory and only systems that allow scavenging and effective pollution control are recommended.
The Humphrey ADE system provides effective solutions to pollution by:
- a reduction at source as low fresh gas flows are used in all modes of use. An average of only 3-4 litres/min is required for adults, 2-3 l/min for children and when recycling through soda lime flows of about 1 litre/min.
- placing the exhaust valve back at the anaesthetic machine which allows for simple scavenging of waste gases away from the operating theatre.
- enabling scavenging to also be used in paediatric operations by inclusion of the specially designed exhaust valve.
- closing the exhaust valve on the front of a dental mask and directing waste gases to the ADE expiratory tubing connected to the side of the mask. Gases are then scavenged at the ADE system valve.
