Six ventilation strategies for intensive care unit patients without ALI or ARDS

	Strategy
A	Lower tidal volume and lower PEEP (lower VT + lower PEEP)
B	Higher tidal volume and lower PEEP (higher VT + lower PEEP)
C	Lower tidal volume and higher PEEP (lower VT + higher PEEP)
D	Lower tidal volume (lower VT + ZEEP)
E	Higher tidal volume (higher VT+ ZEEP)
F	Higher tidal volume and higher PEEP (higher VT + higher PEEP)

Lower positive end-expiratory pressure (PEEP) <10 mmHg; higher PEEP ≥10 mmHg; lower tidal volume (VT) ≤8 ml/kg; higher VT >8 ml/kg. ZEEP zero end-expiratory pressure
