How frequently should postural drainage be performed for a child with cystic fibrosis?

Postural drainage is an essential treatment for children with cystic fibrosis, as it helps to clear mucus from the lungs and improve respiratory function. Performing postural drainage twice a day is generally considered optimal for managing the airway clearance that is necessary in cystic fibrosis. This frequency allows for adequate mucus mobilization and clearance throughout the day, which is critical for preventing infections and maintaining lung health.

Performing postural drainage once a day may not provide sufficient airway clearance to effectively manage the thick secretions associated with cystic fibrosis. Similarly, three times a day could be excessive for some children, potentially leading to fatigue or decreased adherence to the regimen. Conducting postural drainage after every meal is also not recommended as it may be impractical and could interfere with the child's appetite and digestion, making it challenging to maintain a consistent routine. Thus, the recommendation for twice daily sessions balances effective treatment with practical implementation in daily life.
