Title: Efficacy Study of Physiotherapy for Airway Clearance in Cystic Fibrosis. Randomized Controlled Trials in Single Subjects (N of 1 RCT's).
Brief Summary: The purpose of this study is to investigate individual efficacy in Physiotherapy for Airway Clearance, and to investigate user experience, i.e.utility value and preference.


Options:
A: Inclusion Criteria:

1. Male or female patients with a documented diagnosis of CF aged ≥18 years.
2. Written informed consent.
3. At least day 10 - 14 of IV antibiotic therapy during a hospital admission for a pulmonary exacerbation.
4. Patients must be able to perform acceptable spirometric manoeuvres, according to the American Thoracic Society/ERS (ATS/ERS) standards (Miller, Hankinson et. al. 2005).
5. Patient with an FEV1% predicted of ≥ 40%predicted (Stanojevic, Wade et al. 2008).
6. Patients who are productive of sputum from screening visit to study visit 1 (≥10g over 24 hours).
7. Patients who have been prescribed HTS (Nebusal 7%) and have successfully completed a challenge test.
8. Any other chronic medication must have commenced therapy 4 weeks prior to screening and be willing to continue this therapy for the entire duration of the study.

Exclusion Criteria:

1. Day 1-9 of IV antibiotic therapy during a hospital admission.
2. Patients who are colonized with Burkholderia cepacia complex.
3. Patient who are HTS naive.
4. Patients who have an intolerance to HTS.
5. Patients who are currently participating in another study or have participated in another study with an investigational drug within one month of screening.
6. Clinically significant disease or medical condition other than CF or CF-related conditions that, in the opinion of the Investigator, would compromise the safety of the patient or the quality of the data.
