Respiratory Function Surveillance
Regular monitoring of respiratory function is critical as respiratory insufficiency is common in this type. May include sleep studies and pulmonary function testing to detect early changes.
Chest Physiotherapy
Techniques including positioning, percussion, and breathing exercises to help maintain lung clearance and prevent respiratory complications. Can be combined with assistive devices for secretion management.
Additional treatment options
Respiratory Support Planning
Assessment and planning for potential respiratory support needs, including non-invasive ventilation options. Decisions about respiratory interventions are made collaboratively with families considering quality of life.
procedureSymptomatic Medication Management
Treatment of specific symptoms such as seizures, spasticity, or constipation with appropriate medications. Requires regular review and adjustment based on symptom control and side effects.
medicationEnteral Nutrition Planning
When oral intake is insufficient, planning for gastrostomy tube feeding ensures adequate nutrition and medication administration. Nasogastric tubes may be used short-term while longer-term solutions are arranged.
