WHO and Unicef have worked together to develop an oxygen system planning tool to help countries map out oxygen equipment needs at health facilities for Covid-19 response planning. It includes a WHO Biomedical Equipment Inventory Tool (survey) to collect facility data on the availability of biomedical equipment (oxygen, accessories and consumables) and ventilators at the country level. This data can serve to inform planning and readiness, at facilities and in-country, as well as to inform WHO’s global COVID-19 Supply Chain System of existing capacity so that appropriate equipment gets sent to where it can be absorbed, and in an equitable manner.

Article: Design and Implementation of a Medical Oxygen Concentrator for Resource Limited Settings
- “The aim of this project, The Oxygen Concentrator Project...is the rapid design, prototyping and certification through the Kenya Bureau of Standards of low-cost oxygen concentrator, for use in low resource settings. This will be carried out by a multi-disciplinary team from Cambridge University, The University of Nairobi and Gearbox.” More updates to come from the University.
Article: Project Spotlight: Apollo Oxygen Concentrator
- For an open source design, Helpful Engineering has developed a device inspired by how the Apollo-13 crew overcame potential catastrophic failure of an oxygen tank. Responding to the challenge of Covid-19, anyone can build this oxygen concentrator design at home as a life-saving device with commonly available materials. Read more on an overview of the project and see the design on their GitHub page.
Article: RepRap Oxygen Concentrator Open Source Design
- This is the RepRap Ltd repository for all the information, designs, and data for their open-source Oxygen Concentrator. These are fairly simple devices that work by pressure swing adsorbtion and testing is ongoing.
Resource: Unicef Supply Catalogue
- If you need help supplying oxygen to patients, a list of Oxygen Concentrator devices can be found online on the Unicef Supply Catalogue. This includes a full range of products required to provide oxygen, so decision makers worldwide can purchase the equipment if devices are not available on local markets.
