The Process of Weaning from Mechanical Ventilation

Abstract

Mechanical ventilation is a common process in intensive care units. The weaning period has to be initiated as soon as possible because a delay in recognition that weaning can begin may prolong the duration of mechanical ventilation unnecessarily. The inappropriate management of weaning could influence outcomes; therefore, patients on weaning require continuous attention and intervention. The main objective of this review is to provide a description of the entire scenario and update on outcomes and common recommendations for the correct management of this complex process. The role of modern ventilator modes and non-invasive mechanical ventilation are discussed. Finally, the description and outcomes of a group of patients who have poor outcomes (prolonged weaning group), the importance of their identification, and suggestions for their general management are also presented.

The Process of Weaning from Mechanical Ventilation

“…A number of studies [57][58][59][60][61][62] have evaluated this classification. In these studies, the incidence of the simple weaning group was 30-67% of all patients in whom an SBT was attempted (Fig.…”

“…A summary of these studies [57][58][59][60][61][62] indicates that simple and difficult weaning groups are similar in terms of mortality, re-intubation, tracheostomy, and ICU stay ( Table 2). The prolonged weaning group, however, has been associated with worse outcomes and higher mortality (Table 2).…”
