Mechanical ventilatory suggestions for volume-controlled ventilation

Predicted body weight (PBW)	Men: PBW (kg) = .9 [height (cm)] – 87
	Women: PBW (kg) = .9 [height (cm)] – 92
Tidal volume (VT)	6–9 mL/kg PBW
Positive end-expiratory pressure (PEEP)	6–12 cm H₂O and titrated to oxygenation.
Recruitment maneuver (RM)	30–40 cm H₂O for 10–40 s if SpO₂ < 90% or reduced by ≥3% from baseline.
	May need to limit if hypovolemic or if blood pressure falls during RM.
Plateau pressure (Pplat)	26–30 cm H₂O
	Larger values may be needed with pneumoperitoneum. Consider esophageal balloon.
Respiratory rate (RR)	Titrated to an ETCO₂ of 30–40 mmHg in the absence of other clinical issues. Permissive hypercapnia may be required.
Inspiratory-to-expiratory ratio (I:E)	According to patient’s physiology. Monitor for zero flow at end-exhalation.
Fraction of inspired oxygen (FiO₂)	40%–80%, titrated to normoxia.
