cord-350166-loxe11d6	Garmendia, Onintza	Low-cost, easy-to-build non-invasive pressure support ventilator for under-resourced regions: open source hardware description, performance and feasibility testing	2020-04-20		.txt	text/plain	4274	180	38	Our aim was to design and test an affordable and easy-to-build non-invasive bilevel pressure ventilator to allow reducing the serious shortage of ventilators in LMICs. METHODS: The ventilator was built using off-the-shelf materials available via e-commerce and was based on a high-pressure blower, two pressure transducers and an Arduino Nano controller with a digital display (total retail cost <75 US$), with construction details open source provided for free replication. CONCLUSION: The low-cost, easy-to-build non-invasive ventilator performs similarly as a high-quality commercial device, with its open-source hardware description, will allow for free replication and use in LMICs, facilitating application of this life-saving therapy to patients who otherwise could not be treated. To assess the performance of the novel bilevel pressure ventilator under wellcontrolled conditions, the prototype was evaluated in a bench test using an active patient simulator modelling the respiratory mechanics of patients with different levels of obstructive/restrictive diseases ( Figure 2 ).	./cache/cord-350166-loxe11d6.txt	./txt/cord-350166-loxe11d6.txt
