Delivered tidal volume in the ED
Of the 251 patients mechanically ventilated in the ED, 68 (27.1%) received lung-protective ventilation (<8 mL/kg IBW). Twenty-five patients (10.0%) had tidal volume adjusted while in the ED (n=15, increase in tidal volume; n=10, decrease in tidal volume). Vt = tidal volume; IBW = ideal body weight
