carbon dioxide equivalents (CO2 eq)
normalized by hour for cases receiving
halogenated agents and/or nitrous oxide
is less than CO2 eq of 2% sevoflurane at 2L
FGF = 2.83 kg CO2/hr during the
maintenance period of anesthesia.
Threshold: 90%
Measure Time Period: Intubation to
Extubation time
Success: Mean efficiency less than or
equal to carbon dioxide equivalents of 2%
sevoflurane at 2L FGF = 2.83 kg CO
2
/hr or
total CO2eq for the case is less than or
equal to 2.83 kg CO2.
SUS-03: Global Warming Footprint,
Induction
Description: Total carbon dioxide
equivalents per induction for cases where
halogenated agents and/or nitrous oxide
was administered during the induction
period of anesthesia.
Threshold: N/A
Measure Time Period: Induction Start to
Induction End
Success: N/A (informational measure)
SUS-04: Fresh Gas Flow less than/equal to 2
Liters per minute
Description: Percentage of cases with mean
fresh gas flow (FGF) equal to, or less than
2L/min, during administration of
halogenated hydrocarbons and/or nitrous
oxide.
Threshold: 90%
Time Period: Intubation to Extubation Time
Success: Mean FGF ≤ 2 l/min when inspired
halogenated hydrocarbons is >0.2%, or
nitrous oxide FGF >0.2 l/min, during the
maintenance period of anesthesia.
SUS-01: Fresh Gas Flow, less than or equal to
3 l/min
Description: Percentage of cases with mean
fresh gas flow (FGF) equal to, or less than 3
l/min, during administration of halogenated
hydrocarbons and/or nitrous oxide.
Threshold: 90%
Time Period: Intubation to Extubation time
Success: Mean FGF ≤ 3 l/min when inspired
halogenated hydrocarbons is > 0.2%, or
nitrous oxide FGF > 0.2 l/min, during the
maintenance period of anesthesia.
SUS-06-Peds : Low Fresh Gas Flow, Pediatric
Induction
Description: Percentage of pediatric cases
with a max fresh gas flow (FGF) equal to or
less than a weight-based threshold during
the induction phase of anesthesia
Threshold: 90%
Time Period: Induction Start to Intubation
(or Induction End)
Success: Mean FGF ≤ weight-based max FGF
during the induction period of anesthesia
SUS-05-Peds: Nitrous Avoided, Induction
Description: Percentage of pediatric cases
where nitrous oxide gas was avoided
during induction of anesthesia.
Threshold: 90%
Measure Time Period: Induction Start to
Intubation. If not available, to Induction
End
Success: Nitrous oxide was not
administered during the induction period
of anesthesia.
SUS-07: Nitrous Avoided
Description: Percentage of adult cases
where nitrous oxide is avoided during
anesthesia.
Threshold: 90%
Measure Time Period: Anesthesia Start to
Anesthesia End
Success: Nitrous oxide was not
administered during procedure from
Anesthesia Start to Anesthesia End
