Eight systematic reviews have examined various interventions that affect respiratory function and management of people with SCI. Interventions examined include tracheostomy, respiratory muscle training (RMT), exercise training, abdominal FES, and treatment strategies for the respiratory management of acute tetraplegia. Another systematic review assessed the probability of weaning success, duration of MV, mortality, and their predictors in mechanically ventilated adult patients (Schreiber et al. 2021). These systematic reviews are outlined in Table 2 below; however, the conclusions and recommendations related to these findings are incorporated in the specific sections later in the chapter that summarizes the respective treatments.
