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.
