Already tested and validated, this solution allows the addaptation of non-invasive ventilators into Invasive Mechanical Ventilation.

Using equipment already available on the market and hospitals, on crisis scenarios such as Covid-19 pandemic context, this solution increment immediately the invasive mechanical ventilation capacity available at hospitals worldwide, at a very low cost.

  • Results were submitted on European Journal of Anaesthesiology, peer-reviewed and accepted for publication.
  • Formal Request Submitted to Infarmed (Portuguese National Authority of Medicines and Health Products, I.P.), formally subscripted by 180 doctors (in Portuguese).

Our priorities:

  1. Get paper published.
  2. Spread this information to hospitals and countries where there is a shortage of invasive ventilators.
  3. Get Infarmed Request approved.

Thank you for the update on the validation, Duarte! Do you have any news on the homologation?

Hello Nina,

This solution do not request any further formal homolgation and can be used as of today, regarding that all the used equipments are already homolgated and availabe on Hospitals.

Regarding Infarmed Request (Portugal scope), we still do not have any feedback. Yet, in Portugal the situation is relatively calm and no ventilation shortages are likely to occur.

Therefore, the main focus currently is to make this information available, as soon as possible, to the countries, regions and hospitals where this shortage exists or is likely to exist.
