Weaning protocol applied to this study.
SBT, spontaneous breath trial; PEEP, positive end expiratory pressure; RR, respiratory rate; NIP, negative inspiratory pressure; VT, tidal volume; VE, minute ventilation; CPAP, continuous positive airway pressure; RSBI, rapid shallow breathing index. * Negative inspiratory pressure (NIP) is the lowest pressure generated during a forceful inspiratory effort against an occluded airway, which is determined by occluding the ventilator’s inspiratory port at the end of expiration for 20 seconds and reading the maximum negative pressure registered on the ventilator’s pressure manometer.
