Percussionaire IPV-2C - TRUE-IPV Lung Recruitment Protocol

7
The chart (below) illustrates the typical TRUE-IPV® lung recruitment protocol.
This is a method of preventing recruited bronchial airways and alveoli from deating
to an obstructive end resting position during each expiratory lung deation. It is
accomplished as follows:

1. The positive pressure percussive sub tidal volume is generally delivered in
milliseconds with an i/e ratio (approximating 1:2.5) at an endobronchial
delivery rate of 100 to 300 cycles per minute. The lung is step inated to a
selected peak oscillatory positive pressure (oscillatory equilibrium) which
is cyclically maintained allowing the patient to spontaneously breathe
through the oscillatory program at any time. A Newtonian pumping action
is created to recruit and raise endobronchial secretions.
2. The Phasitron®5 (positioned at the patient’s proximal airway) serves as a
physical-physiological interface with a near instantaneous full expiratory
opening to full inspiratory closing (in milliseconds). The Phasitron®5 vents
the patient’s proximal airway to ambient during the cyclic expiratory phase.
Almost instantaneously, the patient’s proximal airway is vented to ambient
after delivery of repetitive sub tidal volumes, venting the patient’s
endobronchial tree.
