Thus, mechanical ventilation with a tidal volume of 6 mL/kg predicted body weight is recommended, with adjustment of the tidal volume to as low as 4 mL/kg if needed to limit the inspiratory plateau pressure to 30 cm water or less. Increase the ventilator rate and administer bicarbonate as needed to maintain the pH at a near normal level (7.3).
