Algorithm for liberation from mechanical ventilation. BP, blood pressure; CPAP, continuous positive airway pressure; F_iO₂, fraction of inspired oxygen; HR, heart rate; P_aO₂, partial pressure of arterial oxygen; PEEP, positive end expiratory pressure; PSV, pressure support ventilation; RR, respiration rate; RSBI, rapid shallow breathing index; S_pO₂, oxygen saturation.
