Saunders Respiratory Practice

Which statement about postural drainage during chest physiotherapy (CPT) is incorrect?

1. Breathe deeply and slowly for maximum effectiveness

2. Breathe in a fast-paced pattern

3. Maintain the position for 5-10 minutes for drainage

4. Clear secretions following postural drainage

The correct answer is: Breathe in a fast-paced pattern

The statement that involves breathing in a fast-paced pattern during postural drainage is incorrect because effective postural drainage relies on slow, deep breaths. This method maximizes the efficiency of airway clearance by encouraging optimal lung expansion and effective gas exchange. Fast-paced breathing does not provide the same benefits and can actually lead to incomplete clearance of secretions and may even promote respiratory fatigue. The other statements are accurate, emphasizing the importance of maintaining the drainage position for an adequate duration, which enhances the effect of gravity on secretions. Deep and slow breathing aids in the mobilization of secretions, and clearing secretions after postural drainage ensures that any mobilized mucus is expelled, maintaining airway patency and improving respiratory function.
