Question

Quizplus · Accepted Answer

After intubation, the child is mechanically ventilated with 6 to 8 mL/kg IBW with low to moderate positive end-expiratory pressure (PEEP) to assist with distal airway collapse and degree of auto-PEEP present. Larger tidal volumes may be required if prolonged expiratory times and low rates are used. The mode of ventilation and set respiratory rate is determined according to the patient's degree of sedation, peak inspiratory pressures generated, oxygenation, and acceptable levels of PaCO₂. Initially, the FiO₂ is 1.0, with the goal to decrease the level to 0.5 or less when able. Ventilation with permissive hypercapnia is allowed with an inspiratory-to-expiratory ratio allowing for adequate exhalation.
