March 2020

The world is facing the largest global pandemic in 100 years

COVID 19 has exploded across Wuhan province and in parts of Europe with cases closing in on 1M worldwide

According to the New York Times, there are less than 2000 working ventilators to serve hundreds of millions of people in public hospitals across 41 countries in Africa

10 of these countries don’t have access to a single ventilator, including Somalia with over 15,000,000 people

The shortage of serviceable ventilation systems is a reality that many countries face globally well into the COVID 19 pandemic and certainly well beyond

Code Life Ventilator Challenge

The objective of the Code Life Ventilator Challenge is to catalyze the development of a low-cost, easy to use and easy to build ventilator to address the needs of COVID-19 and other respiratory illness in low-or middle-income countries.

  • Needs to be accessible
  • Needs to work
  • Needs to keep working

You can help

We are building a global network of production facilities to manufacture and reproduce the Rideau MkII. Our goal is for the Rideau Mk II to exist as a long-standing white label mechanical ventilation system.

The design can be built, deployed, and maintained locally, so that hospitals will not need to rely on hard-to-source components in order to service their Rideau MkII.

If you are a responsible design firm or manufacturer that can demonstrate the ability to aid in the ethical reproduction of our system, please connect with us via rideau@haply.co.
