Weaning patients from long-term mechanical ventilation continues to be a goal of clinicians and scientists and the hospitals charged with their care. This article describes the science of the "wean" and the "how" of weaning. A goal of scientists has been to develop predictors that determine accurately the optimal time to initiate weaning. ⋯ Quite simply, predictors do not predict. In contrast, methods that decrease variation in care practices have demonstrated positive outcomes. The methods include protocols for weaning trials and sedation and other system initiatives inclusive of a multidisciplinary plan of care or clinical pathway.

Many studies have been published on weaning patients from mechanical ventilation, but few have addressed the unique needs of patients with neurologic impairment. Typically, neuroscience patients remain intubated because of concerns over airway protection or neuromuscular weakness. This article discusses special weaning considerations for this patient population. Neurologic-specific weaning trends from a comprehensive ventilator weaning program are also presented.

ReviewPreventing ventilator-associated pneumonia: evidence-based care.
Ventilator-associated pneumonia is a common complication of mechanical ventilation with significant morbidity and mortality. This article summarizes the data related to specific risk factors associated with ventilator associated pneumonia (patient position, oral health, airway management, and gastrointestinal factors) and provides recommendations for practice based on the present evidence.

ReviewSedation and comfort issues in the ventilated infant and child.
Intubated infants and children require optimal sedation and comfort measures. Key elements that ensure the provision of quality care for these patients include the use of pain, comfort, and sedation assessment tools; pharmacologic and nonpharmacologic strategies; and the inclusion of the patient and parents as part of the team. This article describes approaches for using sedation and ensuring comfort in these patients. Application of research and the education of team members and the patient and family are crucial aspects of care and are also discussed.

ReviewAirway pressure release ventilation and pediatrics: theory and practice.
Airway pressure release ventilation (APRV) facilitates oxygenation and ventilation by maintaining an elevated baseline airway pressure similar to continuous positive airway pressure (CPAP). APRV differs from CPAP only by the addition of regular, brief release of airway pressure to facilitate carbon dioxide removal. The baseline pressure maintains a near continuous airway pressure to facilitate recruitment, improving ventilation and oxygenation. Pediatric patients who have recruitable lung disease may be well suited to the application of APRV.
