In this article, we introduce a portable and low-cost ventilator that could be rapidly manufactured, to meet the increasing demand of ventilators worldwide produced by COVID-19 pandemic. These ventilators should be rapidly deployable and with functional capabilities to manage COVID-19 patients with severe acute respiratory distress syndrome (ARDS). Our implementation offers robustness, safety and functionality absent in existing solutions to the ventilator shortage (i.e., telemonitoring, easy-to-disinfect, modularity) by maintaining simplicity. The design makes use of a manual resuscitator as the core respiration component activated by a compression mechanism which consist of two electronically controlled paddles. The quality measurements obtained after testing on a calibrated artificial lung demonstrate repeatability and accuracy exceeding human capabilities of manual ventilation. The complete design files are provided in the supplementary materials to facilitate ventilator production even in resource-limited settings. The implementation of this mechanical ventilator could eliminate device rationing or splitting to serve multiple patients on ICUs. (C) 2021 Pontificia Universidad Catolica del Peru.

Descripción
This work has been funded by the 055-2020-FONDECYT GRANT from the Peruvian government and the donations of the enterprises mentioned in our webpage: https://www.proyectomasi.pe/.In addition,the authors would like to thank to all the members of the Masi team, especially to all of the collaborators working at the five institutions involved in this project (BREIN, DIACSA, EAT, PUCP and Zolid). Without all of their effort, professionalism and sacrifice while working steadily during the pandemic; this device would have not existed.
