Extracorporeal life support (ECLS), or extracorporeal membrane oxygenation (ECMO) as it is also known, has been used to support over 45,000 patients to date. Overall survival is 62%. After many years of no change in equipment and technology, there has been a recent flurry of new pumps, cannulas, and oxygenators available for ECLS use. ⋯ The reported success of ECLS in patients with H1N1 during the 2009-2010 epidemic and the improved survival of patients randomized to the ECMO arm of a recently completed adult study of respiratory failure have also brought ECLS into the spotlight much more than other years. Whether these developments will usher in a new era of ECLS expansion to a wider range of patients will require close consideration and observation. Other areas that need to be further refined include anticoagulation management, treatment of bleeding complications, learning to "nurse" patients in an awake state, such as is done in some European (and a few United States) centers, and neurodevelopmental outcome on a long-term basis.

As the basis for this paper, it must be acknowledged that children are not simply small adults. But this acknowledgment must go further: infants are not simply small adolescents. ⋯ Hopefully, with the collaboration of multicenter investigator networks, additional and definitive pediatric data may be on the horizon. In the meantime, sharing data between adult and pediatric populations seems to be an essential approach to the management of critically ill patients.

The mixture of oxygen and nitrogen is usually sufficient to achieve the therapeutic objective of supporting adequate gas exchange. Pediatric and neonatal patients have an assortment of physiologic conditions that may require adjunctive inhaled gases to treat the wide variety of diseases seen in this heterogeneous population. Inhaled nitric oxide, helium oxygen mixtures, inhaled anesthetics, hypercarbic mixtures, hypoxic mixtures, inhaled carbon monoxide, and hydrogen sulfide have been used to alter physiology in an attempt to improve patient outcomes. Balancing the therapeutic potential, possible adverse effects, and the complexity of the technical aspects of gas delivery, it is essential that clinicians thoroughly understand the application of medical gas therapy beyond the traditional nitrogen/oxygen mixture.

Asthma is a multifactorial, chronic inflammatory disease of the airways. The knowledge that asthma is an inflammatory disorder has become a core fundamental in the definition of asthma. Asthma's chief features include a variable degree of air-flow obstruction and bronchial hyper-responsiveness, in addition to the underlying chronic airways inflammation. ⋯ However, this underlying chronic airway inflammation has implications for the diagnosis, management, and potential prevention of the disease. This review for the respiratory therapy community summarizes these developments as well as providing an update on asthma epidemiology, natural history, cause, and pathogenesis. This paper also provides an overview on appropriate diagnostic and monitoring strategies for asthma, pharmacology, and newer therapies for the future as well as relevant management of acute and ambulatory asthma, and a brief review of educational approaches.

Natural and man-made disasters are inevitable and appear to be more common in the current age. Substantial time and effort have been invested and millions of dollars spent on disaster prevention and management. ⋯ Importantly, reunification with family and assurance of safety in this vulnerable group is a priority. This paper addresses issues related to pediatric needs, the medical system's shortcomings in caring for children, and recommendations for action.
