Thirty spontaneous breathing trials were taken with pressure support (PS) of 7, positive end-expiratory pressure (PEEP) of 5 cmH2O and inspired oxygen fraction = 0.4 for 30 minutes in 17 men and 13 women, with an average age of 51.4 (±24.2), who have been intubated for more than 24 hours in mechanical ventilation and are able to go through the mechanical ventilation weaning process. Upon failure of the SBT, the reason for the lack of success should be classified through functional diagnosis, divided into increase of resistance, characterized by decrease in respiratory rate (FR35), decrease of chest expansibility, pulmonary auscultation with minor vesicular groan diminished or ceased, noises from crackling or small bubbling and usage of accessory inspiratory muscle formation or still alteration of functional reserve.
