Our mission is to develop a Field Emergency Ventilator (FEV) system to be used in an emergency situation, where a large number of basic ventilator systems are required. We are working closely with a core design team of 30+ area experts, external organisations and other open source groups to develop a number of viable concepts for testing.

The overall goal is to develop & design a simplified, low-cost and open-source emergency-use ventilator, producible at scale to aid the treatment of COVID19 patients. 

This open source design project is consolidating findings from experts globally to accelerate the development of working prototypes. Working closely with OpenLung Canada, and their designers, a number of concepts are being finalised for prototyping and testing. The project fully embraces the Open Source ideal, with all files made available online as the project progresses. 

This low-resource Field Emergency Ventilator (FEV) is intended to be a simple, reliable, safe and easy to use device that consists mostly of 3D printed parts and uses a Bag Valve Mask (BVM). This is an emergency field solution that can be relatively easily mass produced with certified components and rapidly deployed by general care workers on the front-line fight against COVID-19. We have been working in close consultation with frontline healthcare workers and other related bodies to ensure the development of a viable solution


This project was jumpstarted by the COVID-19 global pandemic as a result of the community discussion on a Facebook group called Open Source COVID19 and OpenSourceVentilator, Trevor Smale created a GitLab project for a new open-source product called OpenLung.

More specifically, this project was created in a discussion surrounding low cost Bag Valve Mask (BVM or AmbuBag)-based emergency respirators wherein prior solutions had been developed. The first device discussed came from an MIT research group comprising of the following persons: Abdul Mohsen Al Husseini, Heon Ju Lee, Justin Negrete, Stephen Powelson, Amelia Servi, Alexander Slocum and Jussi Saukkonen.

The second device arose from a Rice University Mechanical Engineering student group comprising of the following persons: Madison Nasteff, Carolina De Santiago, Aravind Sundaramraj, Natalie Dickman, Tim Nonet and Karen Vasquez Ruiz.

This project seeks to combine and improve the efforts of these two projects into a more simple and reliable device that consists mostly of easy to source or 3D printed parts.

Benefits: Can be mass-produced, touch points use certified components, small and simple mechanical requirements, previous research and testing in this area, adaptable to both invasive tubing and masks.

Bag Valve Mask (BVM)

Manual resuscitators, such as the bag valve mask (BVM or Ambu-bag), are frequently used by medical professionals in emergency situations. The BVM is the core component in all OpenLung ventilator designs, as with many other design from other groups.

It is reliable, dependable, widely available, relatively cheap and well know to all medical professionals.

The BVM model from Openlung allows teams to develop novel ventilator designs and producing concept 3D models for validation.

OpenLung / Open Source Ventilator offers the Material as-is and as-available, and makes no representations or warranties of any kind whatever concerning the Material, whether express, implied, statutory, or other. This includes, without limitation, warranties of merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable.

Any ventilator system that has not been approved by a competent medical device regulatory authority may not deliver to the user the ability to properly monitor and control tidal volume, inspiratory pressure, inspiratory: expiratory ratio, heart rate, nor provide the user with the ability to monitor and control positive-end expiratory pressure (PEEP), peak inspiratory pressure (PIP) or to adapt to individual patient requirements. Inability to monitor and/or control any of these factors can cause death or serious permanent injury.
The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.
