Understanding wasted/ineffective efforts in mechanically ventilated COPD patients using the Campbell diagram

  • Theodoros Vassilakopoulos
Chapter

Abstract

Wasted or ineffective efforts are inspiratory efforts that fail to trigger the ventilator [1]. Nearly 25% of mechanically ventilated patients exhibit ineffective efforts which are even more frequent in COPD patients [2]. The pathophysiology of wasted efforts can be illustratively presented using the Campbell diagram.
