How should bronchodilators be administered in relation to chest physiotherapy for a child with cystic fibrosis?

Administering bronchodilators before chest physiotherapy is considered optimal for children with cystic fibrosis because this approach helps to open the airways and improve airflow. By doing so, the secretion clearance during chest physiotherapy is enhanced, making the therapy more effective. Chest physiotherapy aims to mobilize secretions, and if the airways are dilated from the bronchodilators, the child can better expel mucus. This coordinated approach maximizes the benefits of both treatments, facilitating better lung function and reducing the risk of respiratory complications associated with cystic fibrosis.
