Is this a) delayed triggering, b) a flow asynchrony, c) an ineffective effort, or d) delayed cycling?

(1) Upward conavity preceding the end of the mechanical breath

Answer: Flow asynchrony

Flow asynchronies occur when the level of assistance provided by the ventilator does not match the actual need of the patient. In this example, the patient’s demand is higher than the flow delivered by the volume-controlled mode.

Common possible causes:

  • Inappropriate selection of ventilation mode or low flow settings (only in volume-controlled modes)
  • High inspiratory effort
  • In volume-controlled modes: Inappropriate flow settings
  • In pressure-controlled modes: Inappropriate pressure ramp (P-ramp) settings
