A goal for most patients on mechanical ventilation is to be weaned from the ventilator. The weaning process is highly dependent on the patient's pathology, but the final common pathway to ventilator independence always includes at least one trial of spontaneous breathing. Trials of spontaneous breathing have been shown to accurately predict the success of spontaneous breathing.〔Yang K, Tobin MJ, A prospective study of indexes predicting the outcome of weaning from mechanical ventilation. N Engl J Med 1991;324:1445-1450〕 == Indications for trials of spontaneous breathing == * fraction of inspired oxygen (FIO2) less than 50% * Positive end expiratory pressure (PEEP) less than 8 cm water * "Minimal vent settings" * * e.g., ratio of arterial partial pressure of oxygen to FIO2 (P/F ratio) in the vicinity of 400 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spontaneous breathing trial」の詳細全文を読む スポンサード リンク
