surplus

fresh-gas flow
The bar graph indicates the qualitative utilization of
the fresh-gas flow. If the fresh-gas delivery is more
than 1 L/min above the gas consumption, the eco-
nometer will indicate surplus. Below this level, uti-
lization of the fresh gas is considered efficient. If
less fresh gas is delivered than is needed by the pa-
tient, a fresh-gas deficit is indicated by the red area
in the bar graph and a fresh gas alarm is generated.
Gas consumption depends on:
– the patient's uptake,
– leakage, and
– the CO volume absorbed.
