Abstract

An anesthesia system includes a volume reflector, a breathing circuit, a processing unit, and a display operatively connected to the processing unit. The processing unit is configured to provide a status indicator on the display for gas in the volume reflector, the status indicator including a graphical representation of an extent of a driving gas of the volume reflector and/or a patient gas in the volume reflector, and/or a flow of gas and a direction of the flow in the volume reflector, and/or a waste gas flow out of the volume reflector relative a fresh gas flow in the system, and/or a re-breathing fraction (RBF), and/or a balance between the fresh gas flow and patient uptake and/or leakage of gas from the breathing circuit.
