Overview
COPD management and airway clearance techniques represent the cornerstone of pulmonary rehabilitation in clinical practice. Understanding these protocols is vital for exams as they bridge the gap between respiratory physiology and hands-on therapeutic interventions for patients with chronic airflow obstruction.
Goals of Physiotherapy in COPD
The primary objective of physiotherapy in COPD is to optimize functional capacity, reduce dyspnea, and manage secretions. It focuses on breaking the cycle of inactivity and improving the mechanical efficiency of breathing.
- Improve exercise tolerance and endurance
- Decrease frequency of exacerbations
- Enhance quality of life and ADL performance
- Retrain respiratory muscles
- Education on energy conservation techniques
Airway Clearance Techniques (ACTs)
ACTs are manual and mechanical procedures used to clear excess bronchial secretions that impair ventilation. Mastery of these techniques is essential for preventing secondary respiratory infections.
- Postural drainage with percussion and vibration
- Active Cycle of Breathing Technique (ACBT)
- Autogenic Drainage (AD)
- Positive Expiratory Pressure (PEP) therapy
- Forced Expiratory Technique (FET) or 'huffing'
Breathing Retraining Strategies
These strategies aim to reduce the work of breathing and decrease air trapping, which is common in COPD patients. Clinicians teach these to control respiratory rate and improve alveolar ventilation.
- Pursed-lip breathing to prevent airway collapse
- Diaphragmatic breathing to recruit primary muscles
- Pacing of breathing during physical activity
- Upper chest mobilization exercises
Exam Tip
Always prioritize the sequence of ACTs—start with breathing control, progress to thoracic expansion exercises, and end with the Forced Expiratory Technique (FET) to minimize airway collapse.
Common Mistakes
- Confusing the indications for percussion versus vibration in patients with fragile rib cages
- Failing to mention the 'huff' technique, erroneously prioritizing vigorous coughing
- Ignoring contraindications for postural drainage such as unstable cardiovascular status or recent hemoptysis
