March 29th


Very busy week helping ventilator initiatives around the globe and securing funding for this initiative when we get to the scale production phase.

We were very lucky this week to obtain 9,000 million pesos (2 Million US) funding from Postobon and 1,000 Million (about 200K USD) from Brinsa. These two are consumer products companies from Colombia who believe in how we can help through innovation to solve this crisis. We had also had an $ 80,000 USD grant from Bancolombia, one of Colombia's largest banks. This is more fuel for this project to move forward quickly.

We have learned many interesting things over the past few days. so we have learned several things:

1.) it is incredibly hard to guarantee PEEP pressures with the valves in disposable Ambu bags. The compliance in the system is too high and, at least the ones we have tested have a variation of around 5cmH2O.

2.) Disposable PVC Ambu bags will last around 3 days in continuous ventilation, after this, they will stop returning to their original shape. so anyone using these ventilators in ARDS has to know and track this durability as patients tend to be ventilated for longer time frames. We are currently working on the ideation of more alternatives to replace the Ambu bag with something else that can be more durable.

Also as the developments advance we are starting to be ready for testing of the ventilator concepts in live animal models. As the designs get more finalized we can share more information. This video by Mauricio Hernandez from the UdeA team made this awesome video, one of several explaining the whole principle of the pneumatically actuated ventilator concept. Sorry, the video is in Spanish but I think this will be of great help for people around the world who want to replicate this model.

I hope to be releasing some more good news soon!!!

I want to send a thank you message to all the teams that are working tirelessly to make this thing viable and we'll continue to focus on making as many ventilators as possible as fast as possible.

  1. some information from MIT about emergency ventilator:

    Gracias por su esfuerzo.

  3. Thank you very much. It is great. Muricio I sent a message by Link is code for arduino an Eng from india create.

  4. first, i must commend your efforts and goodwill. you are of greats. keep on doing the good job

  5. Estimado, desde Keepex sur de Chile también trabajando en prototipos, el diseño es open source? dónde se pueden conseguir los documentos respecto a sensores, monitoreos? gracias!

  6. buenas me gustaria saber si tiene la programacion en arduino y los componentes electronico , gracias

  7. muchas gracias, Dios los bendiga

  8. Tesla ventilator progress:

  9. Vivo en orlando.orgullosa de uds mis paisanos.Dios los bendiga y Los ilumine.

  10. Hi
    Do you have an English version available for this.

  11. Porque se utilizan 4 flujometros y no solo 2, he leido la informacion del blog no he encontrado depronto el insight de ese punto. Gracias

  12. Keep it up. Thank you for the info. Let's beat covid. We can make it.

  13. El 29 de marzo informaron anunciaron que estaban listos para el inicio de pruebas con animales. No hay nueva información sobre qué pasó con esas prueba y con las pruebas preclínicas?
