Pulmonary Modulation Technology (PMT) represents a major advance in the field of respiratory care. PMT has made available a number of new treatment modalities that were not previously possible. PMT uses a unique adjustable Dual-Area-Valve mechanism (U.S. patented and other worldwide patent pending) to naturally sense and respond to a patient's pulmonary requirements and to provide reliable ventilatory support and treatment. The unique PMT technology and the contained mechanism have made it possible to develop single patient, disposable, automatic, portable ventilatory support and treatment products which provide maximum reliability, quality, and cost effectiveness. PMT is very responsive to the pulmonary needs of the patient. At high frequency the technology generates oscillations approaching the natural pulmonary frequency of the patient, providing maximum percussive penetration through the bronchial tubes. At low frequency PMT is fully responsive to the patient, ensuring maximum ventilatory synchronizations and comfort.

The VAR®(VORTRAN Automatic Resuscitator) is a unique single patient use, disposable resuscitator for use with patients weighing (10Kg & above). It provides consistent, reliable, hands free ventilatory support via a mask or endotracheal tube using a continuous gas flow source.

VORTRAN Airway Pressure Monitor (APM)
Monitors patient ventilation parameters
Works with all VAR models
Adult and pediatric models
Alarm display with flashing red LED and audible sound
Easy to set up and use

The VORTRAN®-APM (Airway Pressure Monitor) is a battery (9 VDC) operated, portable, self-contained device that is
connected to the patient via the connection kits (various configurations) to monitor cycling conditions of resuscitators,
such as the VORTRAN® Automatic Resuscitator.
AIRWAY MONITOR
MONITORS: The APM is designed to monitor the operation of the VAR® device when it is connected to a patient. The APM will
display airway pressure like a pressure manometer. The LCD shows Peak Inspiratory Pressure (PIP) and Positive End Expiratory
Pressure (PEEP) in cm-H2O. Other respiratory functions such as Respiratory Rate (RR) in breaths per minute, Inspiratory Time
(IT) and Expiratory Time (ET) in seconds, and I:E Ratio are also displayed on LCD using the same airway pressure signals.


White Paper Release:
A short testimonial below was written by a user in the pre-hospital market. Robert Kohler EMT-P has used the VAR® VORTRAN Automatic Resuscitator for several years, and has written an abstract on our device called, “The Control of End tidal CO2”, by Robert Kohler EMT-P, Stamford Emergency Medical Service. The VAR® is a short term use disposable ventilator perfect for use on patients 10kg and above, and is ideal for use during transports, MRI/CT procedures, disaster preparedness, and in place of a bagged valve mask system which gives the clinician a superior support during critical times of resuscitation. Recently, Robert experienced a new incident using the VAR® on a child who is inflicted with Epileptic seizures. Normally it is suggested that the VAR® be used with a cuffed endotracheal tube but due to the size of the patient an uncuffed tube was placed in the child. Robert explains the events that follows below;

I arrived on the scene at a doctor’s office to find a 6yo 25 kg girl in status epilepticus caricaturized by right arm / leg shaking and facial twitching during which the patient exhibited ataxic and ineffective respirations. The patient’s doctor elected to intubate the patient, with a 5.0 un-cuffed tube, who currently had an O2 saturation of 70%. Post intubation the patient began to seize again and it became apparent that the BVM was hampering what little respiratory effort that patient had left.

The BVM we all commonly use in the field has one major drawback when ventilating a patient with an intrinsic respiratory effort. The patient does not have the ability to exhale while you are pushing air in. Consequently there is an ensuing struggle of air movement. Instinctively the action of the practitioner is to push harder to force air in and at the same time the patient try’s harder to force air out. In the lab or operating room where they don’t often have an emergent setting the therapist can often concentrate and “sync”, so to speak, with the patients ventilatory effort. However, in the field it is very different story.

To circumvent the battle I opted to use the Vortran Automatic Resuscitator (VAR). My concern was that the tube used was un-cuffed and we may not be able to create a seal under pressure. Thankfully I was wrong! I applied the vent and set the PIP initially to 15cm of water pressure and the vent worked flawlessly. I can only surmise that the conical nature of the pediatric away met the ET tube and created a seal. I eventually increased the PIP to 20cm of water pressure and although the patient continued to have sporadic seizures despite the medications administered she was able to comfortably exchange air, though still having ataxic respiration, because she could still exhale against the 20cm of PIP and during inhalation was assisted with 100 FiO2, and in addition, during periods of apnea was automatically ventilated at a rate of 22 breaths per minute.
