This document outlines chest physiotherapy procedures for children and neonates. Chest physiotherapy aims to clear the lungs of secretions, promote respiratory health, and instruct caregivers. It involves techniques like percussion, vibration, positioning, and suctioning. For children, the procedure includes having them cough after percussion and vibration. For neonates, the focus is on gentle techniques and monitoring their oxygen levels. Proper documentation of each session is also emphasized.
