a. Muscle atrophy
b. Respiratory alkalosis
c. Ventilator dyssynchrony
d. Increase in mean airway pressure

High or low flow rate settings can cause the patient to be out of synchrony with the ventilator. The higher the flow rate the shorter the inspiratory time. Incorrect sensitivity settings can lead to auto-triggering or "locking out" the patient.
