Spontaneous Breathing Trial with T-Tube
Discontinuation of mechanical ventilation involves not only the ability to sustain spontaneous breathing but also the ability to protect the airway after extubation. The definition of successful weaning is fairly straightforward: most clinicians agree that a patient has been successfully weaned when he remains extubated within 24 to 72 hours after discontinuation of ventilatory support [1-3]. However, weaning failure may be provoked by two different causes: either the necessity of reintubation or the inability to tolerate a spontaneous breathing trial.
