Table 1 Ten Ventilator Settings Collected Automatically Using the Medical Information Bus (MIB)

Ventilator Settings	Units
Fraction of inspired oxygen (Fio2) ∗	%†
Positive end-expiratory pressure (PEEP) ∗	cm H2O
Respiratory rate ∗	breaths/min
Tidal volume (VT) ∗	mL
Pressure support ∗	cm H2O
Peak inspiratory flow rate	L/min
Low minute ventilation alarm limit	L/min
High pressure alarm limit	cm H2O
High respiratory rate alarm limit	breaths/min
Low tidal volume alarm limit	mL

^∗ Denotes ventilator settings that were used in the logic of computerized ventilator management protocols that were used in the study intensive care units.

^† In the computer system, the term Fio₂ was associated with a percentage (e.g., 40% or 100%) rather than a decimal fraction (e.g., 0.40 or 1.0).
