I need to know what is ventilator asynchrony?

Patient-ventilator: I am sure the one you are talking about is when the patient is taking breaths and the ventilator is pushing pressure or air. It results in increased pressures in the lungs and can cause barotrauma. (there is also that one that we use separate ventilation for each lung.) we want the patient breath and the ventilator breath to recycle and synchronize with each other. Space too short to fully explain.
