Children with spinal muscular atrophy demonstrate a wide range of respiratory compromise3
Respiratory compromise in children with infantile-onset (consistent with Type I) spinal muscular atrophy may be differentiated into 3 categories3:
- Infants ≤5 months of age who require both continuous ventilatory support and non-oral nutritional support
- Infants with ineffective cough who develop acute respiratory compromise during upper respiratory tract infections and require non-oral nutritional support before 24 months of age
- Infants who do not develop respiratory compromise or who do not require non-oral nutritional support until after 24 months of age (approximately 10% of all children with infantile-onset spinal muscular atrophy)
Ventilatory support provided in the home can range from noninvasive ventilation (e.g., nasal mask) to invasive ventilation (e.g., permanent airway, such as a tracheostomy tube)4
