NCT01926275

Brief Summary

The aim of this study is to determine whether noninvasive positive pressure ventilation with inspiratory muscle training can improve quality of life and respiratory muscle strength than noninvasive positive pressure ventilation or inspiratory muscle training alone.

Eligibility Criteria

Age40 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 40-75 years, male or female.
  • Have spirometric evidence of COPD with an FEV1 of \< 50% predicted and FEV1/FVC \< 0.70, measured within the last 6 months (GOLD stage III and IV). Stable disease since 4 weeks or more prior to randomisation.
  • PCO2 of 7 kPa, combined with a pH of 7.35 or above. These gases must be measured after 30 minutes breathing room air in sitting position
  • No treatment with NPPV and respiratory muscle training in the last 8 weeks

You may not qualify if:

  • Smokers can be excluded;
  • Diseases of the lung or thorax besides COPD: OSA Advanced pulmonary fibrosis, advanced bronchiectases, active tuberculosis, post tuberculosis syndrome, pneumonia, severe kyphoscoliosis, tracheostoma, neuromuscular diseases, or any other disorder, which might result in elevated PCO2
  • Local derangement of the face, skin, tongue, upper airways, larynx and upper oesophagus.
  • Severe chronic diseases except COPD, hindering the patient to follow the schedule of this study
