Brief Summary
The purpose of this study is to compare the effect of three airway secretion clearance techniques (chest physical therapy, flutter device and high frequency chest wall oscillation) on decline in pulmonary function over a three year period in patients with cystic fibrosis.

Therapy prescribed twce daily for twenty minute sessions. High frequency chest wall oscillation (HFCWO) applies sharp compression pulses via an air-pulse generator and inflatable vest. HFCWO generates transient increases in airflow at low lung volumes, cough-like shear forces, and alterations in the consistency of secretions.
Therapy was prescribed twice daily for 20 minute sessions and included airway vibration, oscillating PEP, and forced expiratory technique (FET) with coughing.
Each of the six positions are to be clapped or vibrated for 4 minutes. After each position the patient is to do three forced expiratory techniques (FET) and cough, continue with FET and coughing until all mobilized mucus has been cleared.
Eligibility Criteria
You may qualify if:
- A proven diagnosis of CF as evidenced by a positive sweat test (as documented by a sweat chloride \>60 mEq/L by quantitative pilocarpine iontophoresis), or by the presence of two known CF mutations.
- Aged 7 or older.
- FEV1 \>45% (Knudson).
- Able to perform reproducible maneuvers for spirometry at screening as defined by the American Thoracic Society (ATS) and European Respiratory Society (ERS) guidelines.
- Willing to participate in and comply with the study procedures, and willingness of a parent or legally authorized representative to provide written informed consent.
You may not qualify if:
- Hospitalization for complications of CF, or a respiratory exacerbation resulting in - treatment with IV antibiotics within 60 days prior to screening.
- Use of any investigational drug or device within 60 days prior to screening.
- An episode of gross hemoptysis (\>249 ml) within 60 days prior to screening, or during the course of the study.
- A pneumothorax in the six months preceding the study or during the course of the study.
- Patients who are pregnant or become pregnant.
- Patients colonized with Burkholderia cepacia.
