Section snippets
METHODS AND MATERIALS
The study was approved by the Human Use Committee of Bronson Methodist Hospital. Informed consent was obtained from all participants and the parents/guardians of those patients under 18 years old.
Participants with CF diagnosed by clinical history, physical examination, and standard pilocarpine ionotophoresis16 were recruited from the Cystic Fibrosis Center at Michigan State University/Kalamazoo Center for Medical Studies. Patients with a history of pneumothorax, pulmonary surgery, or with
RESULTS
Characteristics of the nine participants, including their severity of CF, are indicated in Table 1. The participants in this pilot study represented a wide range of ages from 7.4 years to 40.1 years old, with moderate to excellent disease severity. Participants tolerated all respiratory treatment without adverse consequences. Subjectively, participants reported no discomfort with use of IPV compared with conventional P&PD therapy.
Pulmonary function data for the three treatment regimens are
DISCUSSION
This pilot study compared a novel mechanical device, the IPV-1, with standard chest physiotherapy in ambulatory patients with CF. The IPV-1 is a lightweight, self-contained instrument that simultaneously combines two effective methods of tracheal-bronchial secretion mobilization: chest percussion and the delivery of an aerosolized bronchodilator solution. Facilitating clearance of mucus may allow greater small airway patency and increased expiratory flow rate, with more effective removal of

2013, Paediatric Respiratory ReviewsCitation Excerpt :It is proposed that the percussive oscillatory vibrations enhance movement of retained secretions, high density aerosol delivery hydrates viscous mucous and the PEP feature recruits alveolar lung units, prevents airway closure and assists in expiratory flow acceleration.38 A number of studies have compared IPV to other chest physiotherapy techniques (conventional physiotherapy, flutter and HFCWO) in CF and have reported equal efficacy.38–40 Mucociliary clearance may be optimised by combining IPV with the inhalation of HTS and/or using it in conjunction with other ACTs such as AD and ACBT.
