ABSTRACT:
In a method and device for reducing the carbon dioxide content in a dead volume intended for connection to the respiratory system of a patient, and an anesthesia apparatus embodying such a device, a flow of gas is generated from an outlet associated with the dead volume and the gas is conducted through a carbon dioxide absorber, and the gas after passing through the carbon dioxide absorber is returned to an inlet associated with the dead volume.
