Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)

Primary Outcome Measures:
  • The primary endpoint will be time to readiness for discharge. [ Time Frame: Hospital days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Secondary endpoint total length of hospital stay. [ Time Frame: Days ] [ Designated as safety issue: No ]
  • Duration and number of doses of bronchodilator therapy [ Time Frame: Day ] [ Designated as safety issue: No ]

Enrollment: 2

Study Completion Date: July 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Patients will receive HFCWO therapy via the VEST(TM). Each Vest treatment will be accompanied by a simultaneous nebulized bronchodilator treatment.
Device: High Frequency Chest Wall Oscillation via Vest (Hill-Rom Vest(tm))
Simultaneous to bronchodilator treatment via nebulizer (regular treatment), patients will receive 15 minutes of HFCWO via the Vest.
Other Name: Hill-Rom Vest(tm)
Sham Comparator: 2
Regular nebulized bronchodilator treatment. Sham Vest treatment as investigator is blinded to whether patient actually received Vest treatment.
Device: Regular nebulized bronchodilator treatment.
Sham Vest treatment.
