Using high inspiratory flows in patients with chronic airflow obstruction receiving flow-limited mechanical ventilation can have several beneficial effects. Firstly, it can decrease the work of breathing as it helps to overcome the increased resistance in the airways. Secondly, it can improve gas exchange by promoting better ventilation-perfusion matching and increasing the tidal volume. Lastly, it can decrease auto-PEEP (positive end-expiratory pressure) by allowing for more complete exhalation and preventing air trapping. Therefore, all three options (1, 2, and 3) are correct.
