Inadequate Assessment of Patient–Ventilator Interaction Due to Suboptimal Diaphragm Electrical Activity Signal Filtering

Jonkman et al. (2020) conducted a letter in Mechanically ventilated patients (n=17). EAdi signal filtering by ventilator software vs. Esophageal pressure (Pes) measurement was evaluated on Proportion of expiratory EAdi peaks >0.1 µV representing true ineffective efforts. Cardiac activity-related artifacts are frequently present in EAdi signals filtered by ventilator software, with only 8.8% of expiratory EAdi peaks representing true ineffective efforts.
