Primary Outcome Measures:
  • Expectorated sputum (gram) [ Time Frame: 8 weeks ]

    Total amount of expectorated sputum (g) will be collected and weighed wet after each intervention for eight weeks, using a Mettler TOLEDO Weighing Balance (EL 202, accuracy: 0.01 g).

    N of 1 trial design. Each trial consist of eight pairs (8 weeks) of treatment periods with two interventions each week (one with Cough Technique and one with Forced Expiration technique), 16 treatments for each participant. Outcome measure after each treatment.

Secondary Outcome Measures:
  • Patient's experience, i.e. perceived utility value and preference of technique. [ Time Frame: 8 weeks ]

    Utility value: Measured by self-reported questionnaire after completion of each intervention in week 8.

    Preference: Measured by three self-reported questions after both interventions in week 8.

Other Outcome Measures:
  • Physiological measurements [ Time Frame: 8 weeks ]

    Oxygen saturation and heart rate measurements in the beginning and at the end of each intervention.

    Pulmonary function tests (week 2): measurements before and after each intervention with spirometry.

  • Health related quality of life (HRQOL) [ Time Frame: 8 weeks ]
    HRQOL measured by the Cystic Fibrosis Questionnaire Revised (CFQR-R), i.e. respiratory symptoms, in the beginning and at completion of the study.
