(A) Reverse triggering was defined as an electrical activity of the diaphragm waveform starting after pressurization onset of mandatory breaths. Blue lines indicate onset of mechanical breath. Yellow dashed lines indicate the electrical activity of the diaphragm onset. (B) Double-cycling was defined as reverse triggering causing a patient-triggered breath with breath stacking. Yellow dashed lines indicate the electrical activity of the diaphragm onset. Paw, airway pressure.
