The ventilator mode that the nurse expects will be set for a client with a tracheostomy who is beginning to take spontaneous breaths at his own rate and tidal volume between set ventilator breaths is: Pressure-supported ventilation mode.
Pressure-supported ventilation mode is used to reduce breathing labor and limit barotrauma. It varies from synchronized intermittent obligatory ventilation and aids control in that the degree of support pressure is designed to help the patient's every spontaneous attempt. Pressure support ventilation has the advantage of improving oxygenation while decreasing labor of breathing.
It is to be noted that the downside or disadvantage of this mode is that volume cannot be guaranteed, especially when the mechanics of the lung change. This kind of breathing is frequently utilized to treat people with neuromuscular problems but normal lungs. It is also used to help people transition off of mechanical ventilation.
