Conventional Versus Automated Bag-based Mechanical Ventilator to Support ARDS Patients

This study evaluates the extubation success and compares the survival rate in patients with signs of Covid-19 intubated with Masi, a novel type of mechanical ventilator, or with other conventional ventilators admitted in the ICU of a reference hospital in Lima, Peru between January and August 2021. The Masi mechanical ventilator works by automating a resuscitation bag with promising preclinical results. The key features of Masi are its low manufacturing cost, low dependence on a supply of high volumes of oxygen, low oxygen consumption, flexibility between non-invasive and invasive ventilation, and extended range of working environmental altitudes compared to commercially available ventilators. A retrospective study of variables and outcomes was done. The main goal of this study is to compare the survival rate of respiratory failure patients supported either with Masi or conventional ventilators at Hospital Vitarte II in Lima between January and August 2021.
