Description
Summary:<italic>Goal:</italic> To develop and validatea novel neonatal non-invasive respiratory support device prototype designed to operate in low-resource settings. <italic>Methods:</italic> The device integrates a blower-based ventilator and a portable oxygen concentrator. A novel control algorithm was designed to achieve the desired fraction of inspired oxygen (FiO<sub>2</sub>) while minimizing power consumption. The accuracy of the delivered FiO<sub>2</sub> and the device power consumption were evaluated in vitro, and a formative usability test was conducted in a rural hospital in Uganda. <italic>Results:</italic> The agreement between the set and delivered FiO2 was high (limit of agreement:&#x2212;5.6 &#x00F7; 3.8&#x0025;). For FiO2 below 60&#x0025;, the control algorithm reduced the power drain by 50&#x0025;. The device was also appreciated by intended users. <italic>Conclusion:</italic> The prototype proved effective in delivering oxygen-enriched continuous positive airway pressure in the absence of compressed air and oxygen, holding promise for a sustainable and effective implementation of neonatal respiratory support in low-resource settings.
