Mar 8, 2018. For an assist breath, the patient must trigger the ventilator (sucking in on ETT and generate a change in pressure or flow), then the ventilator.

The main asynchrony is ineffective triggering, defined as failure of a patient’s inspiratory effort to trigger a ventilator breath. Ineffective triggering is caused by dynamic hyperinflation at the.

Dyssynchrony is the effect of the patients respiratory demands not being appropriately met by the ventilator. The patient has their own idea about how to breathe, and the machinery supporting them, instead of making breathing easier, interferes with respiration and increases the work of breathing. Patient-ventilator dyssynchrony has occasionally appeared in the past papers.
