The Covid-19 outbreak challenged health systems around the world to design and implement cost-effective devices produced locally to meet the increased demand of mechanical ventilators worldwide. This study evaluates the physiological responses of healthy swine maintained under volume- or pressure-controlled mechanical ventilation by a mechanical ventilator implemented to bring life-support by automating a resuscitation bag and closely controlling ventilatory parameters. Physiological parameters were monitored in eight sedated animals (t0) prior to inducing deep anaesthesia, and during the next six hours of mechanical ventilation (t1-7).

- The article presents a low-cost, portable ventilator designed for rapid production to address the global demand due to the COVID-19 pandemic, specifically for patients with severe ARDS.
- This ventilator features robust safety mechanisms, easy disinfection, and modularity, using a manual resuscitator activated by electronically controlled paddles for efficient respiratory support.
- Testing shows the device outperforms human manual ventilation, and complete design files are available to aid production in resource-limited settings, potentially alleviating ventilator shortages in ICUs.
