Fast tracking extubation in cardiac surgery is an accepted technique due to improvement in resource utilization.(1) Early extubation of patients after open-heart surgery is supposed to have beneficial clinical effects besides economic advantages. Among these effects are comfort of patients, reduced respira¬tory complications, savings in costs, earlier return of patients to normal life, and easier engagement in activities (which in itself will prevent complications resulting from low mobility). It will be possible to decrease effectively the negative effects of posi¬tive pressure ventilation by reducing the period patients require for mechanical ventilation. (2)(3)
