In recent times, airway clearance has become an increasingly important part of the treatment of patients with excessive bronchial secretions, especially those with cystic fibrosis. The number of airway clearance techniques available has also grown considerably, becoming increasingly more specific. This has allowed patients a greater choice of treatment techniques and has led to a subsequent rise in independence. This paper gives a brief overview of the methods of airway clearance currently being used by physiotherapists in New Zealand. To date, no one method has been shown to be more effective than another. It is imperative therefore, that those involved in respiratory care have a clear understanding of the airway clearance techniques available. This will allow us to provide out patients with the best possible treatment option.
