Strategies to reduce auto-PEEP in mechanically ventilated patients with obstructive lung disease include which of the following?
1) Use high inspiratory flows (60 to 100 L/min) .
2) Apply extrinsic PEEP.
3) Use low V_T values (8 to 10 ml/kg) .
4) Use high respiratory rates (>25/min) .

Strategies to reduce auto-PEEP in mechanically ventilated patients with obstructive lung disease include using high inspiratory flows to decrease inspiratory time and increase expiratory time, applying extrinsic PEEP to counterbalance intrinsic PEEP and improve alveolar ventilation, and using lower tidal volumes to reduce the risk of lung overdistension and further air trapping. High respiratory rates would decrease expiratory time, potentially worsening auto-PEEP.
