Project Omnis - A Free and Open Source Medical Ventilator

Frequently Asked Questions:

Why was the Omnis Ventilator Developed?

We all want to do our part to help battle COVID-19. At Outer Reef Technologies we felt the best way we could help was to develop an effective ventilator which can be constructed simply and affordably in order to save lives around the world. The situation very much resembled Apollo 13 as the NASA engineers only had a single box full of supplies to save the Astronauts lives. The only difference is that there are many more lives at risk here. Our team named the ventilator Omnis from the Latin word for ‘everyone’, aligned with our goal to design and build an affordable and effective ventilator that can be made available to all, worldwide. Our design goal for Omnis was to use as few parts as possible, include only readily available and mass-produced components, and to ensure assembly required only standard tools so that anyone can manufacture them. By developing a mobile app we were able to decrease the overall complexity and cost by over 50%. As Omins is designed with sophisticated sensors, the system can be operated and monitored very similar to standard ventilators being utilized in the field today. The majority cost and complexity has been in the firmware and app development which means manufacturing these system has a total part cost of around $500.

Why is the Omnis Ventilator different than other open source medical ventilators?

As the Omnis ventilator incorporates a microprocessor, mobile app, and closed loop sensor feedback we are able to incorporate the same modes and accuracy as current ventilators being used today.

Ventilator Modes:

-Assist Control Volume Ventilation
-Assist Control Pressure Ventilation
-Positive Airway Pressure (CPAP)


-Tidal Volume
-Support Pressure
-Respiratory Rate
-Inspiratory/Expiratory Ratio
-Positive End Expiratory Pressure (PEEP)

No matter your motor controller needs, we have the solution. Our team can develop hardware and firmware for your sensored or sensorless BLDC motor.

Surgical Navigation/Motion Capture

We develop high accuracy and precision navigation systems for the medical and gaming industries. Our systems incorporate IMU, optics, and/or mechanical tracking options.

Surgical Suites

After working decades with the top surgeons, we have brought many Class III medical devices and suites to the industry from concept through clinical trials and 510k submission.

Imaging and Optics

Our team has extensive knowlege and experience developing and manufactiring optical devices ranging from LED fiber optics to rigid and flexible scopes.

High Precision Encoders

As nearly all of our products require the highest level of accuracy and precision, in a small form factor, we typically design our own encoder solution to meet the clients requirements.

Virtual and Augmented Reality

We have partnered with some of the top companies in the world to develop world class virtual and augmented reality devices. Our specialty is in sensor calibration, system integartion and verifcation.

Industrial Product and Packaging Design

Our design team utilizes SolidWorks to design and develop all of the products mechanical components. We utilize FEA and 3D printing to ensure our designs meet all requirements, prior to manufacturing.

Software and Application Development

These day there are apps integrated into nearly every product. We can support desktop, mobile and standalone apps, including apps which are required to integrate with the cloud and/or remote devices.
