Asthma is a chronic inflammatory disorder that results in recurrent episodes of reversible airflow obstruction. Lung hyperinflation results from obstruction or dynamic airway collapse during exhalation. ⋯ Patients who present with asthma have increased inspiratory work of breathing due to lung hyperinflation and auto-positive end-expiratory pressure (auto-PEEP). The goal of acute care treatment is to reverse bronchoconstriction and inflammation, thus reducing dynamic hyperinflation, so that breathing is restored to baseline, unlabored, quiet breathing.

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.

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.

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.

Review Case ReportsSedation assessment: easier said than done!
Sedation assessment commonly is performed in critically ill patients to evaluate their need for, and response to, sedation therapy. Although many sedation assessment scales have been published, few have been tested properly to assure their appropriateness for use in critically ill patients. This article highlights the published sedation assessment scales that have the strongest scientific basis, identifies limitations of the current scales, and suggests characteristics for future sedation assessment scales that would overcome many of the current problems.
