Values are expressed as means ± standard deviations or numbers (percentages). The value of each group is described in comparison to the successful extubation group. APACHE: acute physiology and chronic health evaluation; SOFA: sequential organ failure assessment; P/F ratio: pressure of arterial oxygen to fractional inspired oxygen concentration ratio; RSBI: rapid shallow breathing index; PaCO2: partial pressure of arterial carbon dioxide.
