Physical Rehabilitation Prolonged bed rest and physical inactivity during mechanical ventilation often leads to deconditioning and generalized muscle weakness, and this is considered a contributing factor in ventilator-dependent patients who have difficulty in the transition to unassisted breathing Supporting this contention are studies showing that early physical rehabilitation, including ambulation, is associated with a shorter duration of mechanical ventilation (7) Therefore, early and regular physical rehabilitation (including ambulation in patients who are awake and hemodynamically stable) is encouraged in selected patients to facilitate the transition to spontaneous breathing Sedation Practices Several studies have shown that both deep sedation (where the patient is not arousable) and sustained use of benzodiazepines (midazolam and lorazepam) for sedation are associated with delays in discontinuing mechanical ventilation (8) As a result of these studies, the most recent guidelines on sedation in ventilator-dependent patients (8) include the following recommendations: Maintain a light level of sedation, where patients are easily aroused Avoid or minimize the use of benzodiazepines for sedation Non-benzodiazepine sedatives include propofol and dexmedetomidine, which are described in Chapter 51 Table 30.1 Checklist for Identifying Candidates for a Trial of Spontaneous Breathing Readiness Criteria The management of ventilator-dependent patients requires constant vigilance for signs that ventilatory support may no longer be necessary These signs are listed in Table 30.1 Candidates for possible removal of mechanical ventilation should have adequate gas exchange in the lungs (i.e., PaO 2/FIO2 >150–200 mm Hg and a normal or baseline arterial PCO2) while breathing non-toxic concentrations of oxygen (FIO2
