Cyth Systems Creates Innovative Ventilator

October 2020

San Diego, California – Cyth Systems, an embedded design and systems integration company,announced today that it has developed a low-cost, innovative ventilator.  According to a spokesperson for the company, the design is feature-packed and is not just for the current pandemic.

“We wanted to make sure our ventilator design was useful, that it worked as expected, and that it had applications beyond just COVID”says Joe Spinozzi, CEO and Chief Architect of Cyth Systems.  “We did a lot of research and testing before jumping out with a knee-jerk announcement that we’re making a ventilator.”

During the early days of the COVID-19 pandemic the world recognized the potential for a dramatic shortage of medical ventilators to treat sick patients. Ventilator manufacturers ramped up production while research institutions, hobbyists, and businesses responded with a wide range of creative ventilator designs.

“The problem with many of these solutions is that they cause more harm than good.”says Dr. Steve Tunnell, Founder & Chief Science Officer of Lungtreater, experts in respiratory cardio services.Dr. Tunnell further explains “The danger lies with the alveoli, which are delicate and can become permanently damaged or destroyed when exposed to forced ventilation.  Unfortunately, these solutions are primarily based on manual resuscitation bags which can easily and permanently damage a patient’s lungs.”

“Before getting Steve’s advice, I remember thinking ‘either I am crazy, or everyone else is!’”, recalls Spinozzi.  “Reading the news, I thought these ventilatorsseemed unsafe after just a little bit of research, but many of them already had FDA and UK government approval.  Yet I kept thinking that our simulated lung could easily meet all the necessary design and safety requirements, and Richard agreed!”

Dr. Richard Tallman, CEO and founder of Biomed Simulation, worked with Cyth in the past on a device that can accurately reproduce the complex behavior of human lungswitha pistonthat is pulled or pushed by a very fast electric motor.  Tallman explains, “Bags and balloons are too simple, but the Califia lung simulator design I developed gives us the ability to simulate a healthy lung,or one with any specific conditions.”  Dr. Tallman elaborates, “When Cyth approached me to ask if we could apply the same technology to develop a ventilator, I told them I had been thinking the same thing!”

After developing a simulated heart together in previous years, Cyth worked with Biomed Simulation starting in 2018 to develop a simulated lung, which was completed in early 2020 just before the Coronavirus pandemic appeared.  With the help of Tallman and Tunell, it was a manageable challenge to modify the simulated lung into a low-cost, high-performance ventilator.  The resulting device supports autonomous and assisted breathing modes, has numerous safety and alarm conditions, precise oxygen control, and battery backup, all of which are requirements for use in hospitals. In fact, assisted breathing mode – the ability to detect a patient trying to take a breath and gently assist– is one of the most important minimum safety features of a mechanical ventilator.

With today’s announcement Cyth is prepared to help address the needs for mechanical ventilation driven by COVID-19 and other acute respiratory issues, during the pandemic and beyond.The ventilator is in the validation stages and if there is an emergency need for ventilators in fall of 2020, the device could be ready for FDA approval in a matter of weeks.

Furthermore, the unit makes agreat tool for hospitals that need extra ventilators for emergency use, andis an affordable choice for smaller hospitals and foreign countries.

Anyone wishing to evaluate the ventilator or make contact is urged to contact Cyth Systems, or visit Cyth’s website (
