Obese patients are at risk for respiratory failure leading to mechanical ventilation. The mechanical ventilation strategy for the obese patient includes pressure or volume ventilation, with tidal volumes based on predicted body weight (PBW) ranging from 8 to 12 ml/kg. The head of the bed should be elevated to 30 degrees or higher to improve respiratory mechanics. NIV may be considered post-extubation for 24-48 hours as it can help to prevent re-intubation in obese patients with moderate to severe respiratory distress. Therefore, options 1, 3, and 4 are all appropriate choices for mechanical ventilation of the obese patient, making option D the correct answer.
