Study information
Scientific title

Study hypothesis
We hypothesised that the use of intrapulmonary percussive ventilation (IPV), a technique designed to improve mucus clearance, could prove effective in avoiding further deterioration in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) with mild respiratory acidosis.
Ethics approval
The experimental protocol was approved by the institutional review board of the hospital

Condition
Acute exacerbations of chronic obstructive pulmonary disease (COPD) patients with mild respiratory acidosis
Intervention
Comparison of two groups of COPD:
1. A standard goup: COPD patients with standard treatment alone
2. An IPV group: COPD patients with standard treatment plus IPV

Drug names
Primary outcome measures
Therapy was considered to be successful when it enabled the avoidance of both a worsening of the exacerbation and a decrease in pH to under 7.35 (which would have required NIV), and allowed the patient to be discharged from the ICU.
