Clinical Decision Support for Mechanical Ventilation of Patients With ARDS

Defined as: % of time each patient is on a compliant tidal volume for the duration of mechanical ventilation.

Measured as: VC, PRVC, or VC+ with volume set to 6.5 ml/kg or less for each patient (proportion of mechanically ventilated hours, excluding hours on appropriate CPAP/PS)

Defined as: % of time each patient is on a compliant FI02 and PEEP combination.

Measured as: using recommended (per most recently run oxygenation protocol) PEEP-FIO2 combinations, (proportion of ventilated hours, excluding the first four hours of mechanical ventilation and excluding hours on appropriate CPAP/PS)

Defined as: % of time each patient is managed with the computerized ventilation protocol.

Measured as: Running the computerized ventilation protocol whenever a ventilator check is performed and an arterial blood gas was done within the previous hour, excluding hours on appropriate CPAP/PS

Defined as: % of time each patient is managed with the computerized oxygenation protocol.

Measured as: Running the computerized oxygenation protocol at least every four hours when a ventilator check was performed, excluding hours on appropriate CPAP/PS

Defined as: meeting, or not meeting, the target LTVV compliance of >90% for each patient.

Measured as: VC, PRVC, or VC+ with volume set to 6.5 ml/kg or less for 90% or more of mechanically ventilated hours, excluding hours on appropriate CPAP/PS

Defined as: meeting, or not meeting, the target PEEP FI02 compliance of >70% for each patient.

Measured as: Using recommended (per most recently run oxygenation protocol) PEEP-FIO2 combinations for at least 70% of mechanically ventilated hours (excluding the first four hours of mechanical ventilation and excluding hours on appropriate CPAP/PS)
