Proning the patient and using inverse I:E ratio ventilation can both improve oxygenation beyond increasing the FiO2 or PEEP level. Proning allows for better distribution of ventilation and perfusion in the lungs, particularly in patients with acute respiratory distress syndrome (ARDS). Inverse I:E ratio ventilation, where the inspiration time is shorter than the expiration time, can increase mean airway pressure and improve oxygenation by recruiting collapsed alveoli. Using an expiratory pause can be helpful in assessing lung recruitment and assessing the effectiveness of different ventilator strategies, but it is not a technique for improving oxygenation.
