Respiratory failure is a common complication of acute cardiorespiratory disease and exacerbations of chronic respiratory disease. Respiratory failure is a common problem, particularly in patients with pre-existing respiratory disease but also in previously well patients in the perioperative setting. Respiratory failure is a condition that results when the lungs are no longer able to oxygenate the blood sufficiently or remove CO2 from it. PHYSIOLOGY RESPIRATORY FAILURE inability.

This is a summary of the presentation on the pathophysiology of respiratory impair-ment in pediatric neuromuscular disorders presented as part of the program on pulmonary management of pediatric patients with neuromuscular disease at the 30th annual Carrell-Krusen Neuromuscular Symposium on February 20, 2008. Respiratory failure is a common clinical condition, with a reported incidence of 78–149 per 100,000 people over 15 years of age per year. The pulmonary system is no longer able to meet the metabolic demands of the body with respect to oxygenation of the blood and/or CO2 elimination.
