Describe automatic tube compensation.
What will be an ideal response?
Automatic tube compensation (ATC) is a mode in the Evita 4 ventilator (Dräger Medical) that reduces the airflow resistance imposed by the artificial airway (endotracheal or tracheostomy tube). It allows the patient to have a breathing pattern as if breathing spontaneously without an artificial airway. This type of compensation may facilitate breathing efficacy and reduce the work of breathing throughout the weaning process.

A patient, who is nasally intubated, due to facial surgery, has been successful on her spontaneous breathing trial
She currently has moderate hypoxemia, despite a fractional inspired oxygen (FIO2) of 40% and positive end-expiratory pressure (PEEP) of 5 cm H2O while on volume-controlled continuous mandatory ventilation (VC-CMV).
