The purposes of this paper are as follows (1) to describe the prevalence, etiology, and care settings for children dependent on longterm mechanical ventilation (MV); (2) to provide a brief introduction to MV and weaning; (3) to explore health care utilization and cost of care; and, primarily, (4) to discuss the rehabilitation needs of children dependent on long-term MV including activities of daily living, mobility, communication, psychosocial needs, and recreation and leisure. Children with ventilator dependence are a growing segment of the population of children with special health care needs and often require rehabilitation services. MV is a form of life-saving technology that substitutes for or assists a child's respiratory efforts. Goals for use of MV vary and there are many combinations of MV elements that can obtain desirable results. No standards of care exist for the rehabilitation examination or interventions utilized for children with long-term MV dependence and it remains unclear what effect MV has on the achievement of developmental milestones, daily activities, and participation in daily life.
