Scientific title
Study objectives	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(s)	The experimental protocol was approved by the institutional review board of the hospital
Health condition(s) or problem(s) studied	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
Intervention type	Other
Primary outcome measure(s)	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.
Key secondary outcome measure(s)	Not provided at time of registration
Completion date	31/12/2004

Participant type(s)	Patient
Age group	Not Specified
Sex	Not Specified
Target sample size at registration	33
Key inclusion criteria	COPD patients in acute excerbations and respiratory acidosis with pH between 7.35 and 7.38
Key exclusion criteria	1. The requirement for emergency intubation for cardiopulmonary resuscitation, respiratory arrest, or in the case of rapid deterioration in neurological status (Glasgow coma scale inferior or equal to 8) 2. Hemodynamic instability defined as a systolic blood pressure of less than 80 mmHg or evidence on electrocardiography of ischemia or clinically significant ventricular arrhythmias 3. Failure of more than two additional organs; or tracheotomy, pneumothorax, facial deformity, or a recent history of oral, oesophageal or gastric surgery
