Intrapulmonary Percussive Ventilation (IPV®)
Operational Pressure Control
Controls the peak operating
pressure of the entire unit. This
control at maximum output will
only provide pressure slightly
less than that of the institution.
The optimal inlet wall pressure
is 50 psi (3.4 bar, 345 kPa).
Percussion
Adjusts frequency of pulses,
at a xed i:e ratio
Manual Inspiration
Delivers a regulated source of
gas through the orice of the
Phasitron®5 venturi. The longer
the button is pressed, the
greater the potential for tidal
volume delivery.

Chapter 1: Introduction
Designed specically for non-continuous institutional/hospital use, the IPV®-1C is a
pressure-limited, ow-interrupted and time-cycled ventilator which provides IPV® therapy,
a modality of mechanical ventilation, “Intrapulmonary Percussive Ventilation”.
The IPV®-1C provides high frequency percussive pulses between 100-300 cycles per
minute. These high frequency percussive pulses ramify throughout the airways and
alveolar ducts augmenting diusive ventilation in the gas exchange regions of the lungs,
allowing improved FRC, CO
2
removal, airway clearance, and lung recruitment.
During operation, the IPV®-1C system supplies a continuous dense aerosol mist which is
delivered into the lungs during therapeutic percussion, serving to reduce the adhesive
and cohesive forces of retained airway secretions.
The IPV®-1C, using a Phasitron® 5, provides
intrapulmonary percussive ventilation either
invasively, through an articial airway, or
non-invasively, by mouthpiece, mask, or cannula.
The patient may breathe spontaneously, but
this is not required.
The IPV®-1C can also be used in-line with
conventional mandatory ventilators, delivering
TRUE-IPV® therapy and preventing the need to
switch between devices.
This chapter provides an overview of the IPV®-1C device and TRUE-IPV® therapy.
