^∗ Average number of setting changes recorded in the computer charting application (HELP) per 24 hours.

^† Average number of setting changes recorded by the MIB per 24 hours.

MIB = Medical Information Bus; Fio ₂ = fraction of inspired oxygen; PEEP = positive end-expiratory pressure; V_T = tidal volume; V_E = minute ventilation.
