WARNING and CAUTIONS
WARNING
If the VDR®-4 is connected to a Monitron® II Waveform Analyzer, a
hospital-grade AC power plug is provided. Grounding reliability
can only be guaranteed if connected to a tested, hospital-grade
outlet. Any alteration to proper connection may cause harm to
the patient or personnel associated with the device.
Perform suctioning as necessary. Only proximal airway is moni-
tored; in the event of an obstructed or restricted airway, alarming
may not occur. Proper suctioning procedures should be followed
to maintain a patent airway.
Deviation from manufacturer's suggested assembly could cause
the VDR®-4 to malfunction.
Audible alarming could indicate a potentially harmful situation
and should be attended to immediately. Failure to comply could
result in injury or death to the patient.
See“Pre-Use Checks.”
The Phasitron® breathing circuit is specically designed for use
with the VDR®-4. Any attempt to substitute another circuit or
conguration could result in injury to patients or operator and
damage to equipment.
The VDR®-4 device can be used on a patient with an articial
airway. These devices enhance secretion clearance. Patients must
be assessed pre- and post-treatment for a reduced vital capacity/
FRC or the need for assistance in clearing airway secretions.
Equipment maintenance procedures must be complied with.
Failure may result in injury to the patient or operator and could
result in damage to the equipment.
Proximal airway lter should be changed when large amounts of
water are downstream of lter. Failure to replace the lter when
necessary could result in patient injury and/or damage to the
equipment.
Always check the operational pressure settings on the VDR®-4
before placement of the ventilator on a new patient.
Administration of excessive oxygen to a patient may be harmful.
The prescribed oxygen concentration delivered by the blending
system should be veried with an oxygen analyzer.

It is the user’s responsibility to follow the instructions given in this manual. Keep the operating
instructions near the device to ensure correct operation. If the safety instructions are not
followed, the patient may be at risk.
A WARNING indicates the possibility of injury, death, or other serious adverse reactions associated
with the use or misuse of the device.

IV
Test the operation of the VDR®-4 patient disconnect alarm when
doing pre-use check and pre-setup procedure. An increase in
circuit resistance can prevent proper operations of some alarms.
Speaking valves, heat moisture exchangers (HMEs), and lters
create additional circuit resistance and may aect the performance
of alarms chosen for circuit disconnect protection.
Prior to placing a patient on the VDR®-4 ventilator, a clinical
assessment should be completed to determine the device alarm
settings, alternative ventilation equipment needed, and if an
alternative monitor is required.
Therapists should evaluate how their patients tolerate mechanical
ventilation with the VDR®-4. Auscultation and observation of
the chest and abdomen can be primary indicators of eective
mechanical ventilation.
The VDR®-4 is a restricted medical device designed for hospital
use by respiratory therapists or other trained clinicians under the
supervision of a physician.
The operator of the VDR®-4 is responsible for reading and
understanding the manual before use.
All persons using the VDR®-4 ventilation device must be trained in
its use.
Pre-use checks must be completed before any ventilation is
started on a new patient. If any abnormal function is noted,
do not start ventilation.
Failure to comply could cause injury or death to the patient.
Alarm functions must be tested prior to each use to verify the
capability of the device to detect conditions that could cause
injury to the patient.
Proper care needs to be taken during setup to ensure all
lines running to or from the patient circuit are not crimped or
perforated. Failure to conform could cause malfunction of alarms
and/or pressure limit controls.
Proper support and orientation of the patient circuit must be made
to avoid inadvertent disconnection.
Water traps (if used) should be drained at intervals to prevent the
possibility of injury to the patient.
All guidelines in this manual are only suggested; always follow
hospital or institutional protocols.

Chapter 1: Introduction
Volumetric Diusive Respirator (VDR®)
This chapter provides an overview of the VDR®-4 device and High-Frequency
Percussive Ventilation (HFPV).
Designed specically for hospital use, the Volumetric Diusive Respirator unit (VDR®-4) is
a ow-regulated and time-cycled ventilator which provides high-frequency percussive
ventilation (HFPV). The Phasitron® breathing circuit delivers HFPV and interfaces with
hospital humidication systems. This HFPV system supports both diusive and convective
ow by stacking breaths in cumulative subtidal volumes, allowing for ventilation, airway
clearance, and lung recruitment for most hospital patient populations, neonatal to adult.
The VDR®-4 can be used to treat respiratory conditions including hypoxemia, hypercapnia,
aspiration, smoke inhalation, and ARDS. This unit is paired with the Monitron® II Waveform
Analyzer, which provides accurate, real-time visual waveform, pressures, and alarms,
making the VDR®-4 a versatile tool for critical and intensive care respiratory ventilation.
Demand CPAP/PEEP
Reducing the work of breathing.
Inspiratory Time
Selects the time interval in which the
inspiratory amplitude (set with the
pulsatile owrate) is delivered.
Pulsatile Flow
Determines the amplitude delivered
to the patient during inspiratory
phase.
Frequency
Controls the rate of high-frequency
pulses delivered.
Manual Inspiration
Delivers a regulated source of gas
through the orice of the Phasitron®
venturi.
Operation 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 pressure
setting is 40 psi/2.75 Bar.
