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.

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.

Review Case ReportsCaring for the bariatric patient with obstructive sleep apnea.
Caring for the bariatric patient in the acute care environment poses many challenges to the team delivering care. The management of obstructive sleep apnea with noninvasive ventilation is one priority. Treatment options, including bi-level ventilation and continuous positive airway pressure, and delivery strategies are reviewed in conjunction with other aspects of care that ensure a holistic, comprehensive plan of care. The most effective plan of care for the bariatric patient is one that uses a multidisciplinary coordinated team effort.

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.

ReviewProne positioning in the patient who has acute respiratory distress syndrome: the art and science.
Acute respiratory distress syndrome (ARDS) remains a significant contributor to the morbidity and mortality of patients in the ICU. A variety of treatments are used to support the lung of the patient who has ARDS and improve gas exchange during the acute injury phase. It seems, however, that the simple, safe, and noninvasive act of prone positioning of the critically ill patient who has ARDS may improve gas exchange while preventing potential complications of high positive end-expiratory pressure, volutrauma, and oxygen toxicity. This article provides the critical care nurse with the physiologic rationale for use of the prone position, indications and contraindications for use, safe strategies for prone positioning, and care techniques and monitoring methods of the patient who is in the prone position.
