Abstract
Although mechanical ventilation (MV) can be lifesaving, it is associated with numerous complications, and thus, it should be discontinued as soon as possible. However, determination of the optimal time to discontinue ventilator support can be very difficult. While an experienced physician can frequently judge the likely outcome of a weaning trial, it is desirable to have objective measurements that decrease the dependence on the wisdom and skill of a physician [1–3]. By identifying patients who are likely to fail a weaning trial, such indices can prevent a premature weaning attempt and the development of severe cardiorespiratory and/or psychological decompensation. On the other hand, by identifying the earliest time that a patient is able to resume and sustain spontaneous ventilation, indices help to avoid unnecessary prolongation of the period of ventilator support. Finally, since these indices assess many different physiological functions, they may provide insight into the reasons for ventilator dependency in an individual patient and suggest alterations in management.
