Percussionaire Corporation Intrapulmonary Percussive Ventilator

Intrapulmonary percussive ventilation (IPV) is a therapeutic modality designed to clear and maintain pulmonary airways. IPV is used to mobilize and clear retained secretions, assist in the resolution of atelectasis, and to deliver aerosolized medications. Oscillatory pulsations are delivery by the "Percussionator" which generates high frequency bursts of gas at rates of 100 to 300 cycles per minute (2 – 5 Hz). The mini bursts of air are delivered to the patient's airways at pressures of 10 – 20 cm H20, however this range may be adjusted to match the compliance and resistance of the lung and chest wall.

Three forms of therapy are provided during IPV; percussive oscillatory vibrations which loosen retained secretions, high density aerosol delivery to hydrate viscous mucous plugs, and positive expiratory pressure (PEP) to recruit alveolar lung units and assist in expiratory flow acceleration during a cough maneuver.

IPV can be used as an alternative to conventional airway clearance techniques, i.e. chest percussions and postural drainage, and many cases will provide superior secretion mobilization and removal. Therapy can be provided in the acute care setting as well as the home environment. Additionally, IPV can be used in combination with positive pressure ventilation through a simple interface with the ventilator circuit.
Clinical outcomes associated with IPV include:

  1. Increased sputum production
  2. Improvement in breath sounds
  3. Improved lung and chest wall mechanics (compliance and resistance
  4. Resolution of lung infiltratres and atelectasis as shown on chest x-ray
