case_images: Ventilator graphics from a patient with severe acute respiratory syndrome coronavirus 2
  (SARS-CoV-2) pneumonia receiving volume control ventilation. Airway pressures (yellow
  tracing) falling below PEEP during the inspiratory cycle. The electrical activity of the
  diaphragm (EAdi; white tracing) shown in the bottom graphic and is superimposed over the
  airway pressure tracing.

case_images: Despite the use of square waveform gas delivery with flow support, Figure 1 shows marked asynchrony with inspiratory pressure falling below PEEP during VT delivery and pressure spikes at the termination of the inspiratory phase. In Figure 1 the EAdi waveform is superimposed over the pressure waveform as a preview of what the pressure waveform might be when changed to the NAVA mode.

  ventilatory assist (NAVA) mode.
