Apollo v2 build instructions

• https://github.com/oxycon/ProjectApollo/blob/master/prototypes/Apollo%20v2/docs/Building%20instructions%20-%20prototype%20v2.pdf

Why

• Ventilators need oxygen! (typical FiO2 0.4 … 0.9)
• Oxygen generation is a big problem in developing countries.
  • No established infrastructure.
  • Oxygen bottles are expensive
• People are already looking at alternative (local) ways for producing oxygen

What

• Goal of the Apollo prototype = enabling people around the world to build the prototype as fast as possible
• Focus = Simplicity and speed of build
• Final goal = Enable people to iterate and publish their own designs in the community

How

• Follow the published build documentation
• Buy/source the materials (check out the BOM)
• Build the prototype
• Validate O2 concentration and flow. Use a good O2 and flow sensor.
• Think about risk analysis and assessment: template for Apollo-derived design
• Document and iterate your own design. Publish your findings to the community!

Target

• Output medical grade Oxygen ideally at 93%
• Flow rate of 1-20 liters per minute (5 l/m being standard for oxygen therapy)

Building instructions (prototype v2)

• Achieves O2 concentration out of the box: around 45% @ 5 liters/min (enough for less-critical ventilator use cases)
• Instructables-style (step-by-step) build instructions: https://github.com/oxycon/ProjectApollo/blob/master/prototypes/Apollo%20v2/docs/Building%20instructions%20-%20prototype%20v2.pdf
