A patient with chronic liver disease and metabolic acidosis was intubated and diagnosed with pneumonia and severe ARDS. The ventilator was set in the A/C-VCV (volume controlled) mode, with a Tidal Volume (VT) of 6ml/kg of predicted body weight and an inspiratory time of 1 second.

The curves on the ventilator screen as seen at the bedside can be watched in the video below.

What’s the most plausible explanation for these findings?

b) Superficial sedation
c) Increased respiratory drive
d) Inspiratory flow is set to low
e) Problems in the triggering function of the ventilator
