For a female patient with predicted body weight 60 kg on a 6 mL/kg tidal volume, the VT is approximately:

Tidal volume is set using predicted body weight and a per-kilogram target to minimize volutrauma. With a predicted body weight of 60 kg and a standard target of 6 mL/kg, VT = 60 × 6 = 360 mL. So the approximate tidal volume is 360 mL. The other values would reflect per-kg targets that differ from 6 mL/kg (about 5.7 mL/kg for 340 mL, 5.3 mL/kg for 320 mL, or 6.3 mL/kg for 380 mL), which aren’t the typical initial target.
