Mechanical ventilators are safety-critical devices that help patients breathe, commonly found in hospital intensive care units (ICUs)-yet, the high costs and proprietary nature of commercial ventilators inhibit their use as an educational and research platform. We present a fully open ventilator device-The People's Ventilator: PVP1-with complete hardware and software documentation including detailed build instructions and a DIY cost of $1,700 USD. We validate PVP1 against both key performance criteria specified in the U.S. Food and Drug Administration's Emergency Use Authorization for Ventilators, and in a pediatric context against a state-of-the-art commercial ventilator. Notably, PVP1 performs well over a wide range of test conditions and performance stability is demonstrated for a minimum of 75,000 breath cycles over three days with an adult mechanical test lung. As an open project, PVP1 can enable future educational, academic, and clinical developments in the ventilator space.
机械呼吸机是帮助患者呼吸的安全关键设备,通常在医院重症监护病房(ICU)中使用——然而,商业呼吸机的高成本和专属性限制了它们作为教育和研究平台的使用。我们展示了一种完全开放的呼吸机设备——人民呼吸机(PVP1),它具有完整的硬件和软件文档,包括详细的构建说明和 DIY 成本为 1700 美元。我们根据美国食品和药物管理局(FDA)对呼吸机的紧急使用授权中规定的关键性能标准,以及在儿科环境下与最先进的商业呼吸机进行了验证。值得注意的是,PVP1 在广泛的测试条件下表现良好,并且在三天内使用成人机械测试肺进行了至少 75000 次呼吸循环的性能稳定性得到了证明。作为一个开放项目,PVP1 可以为呼吸机领域的未来教育、学术和临床发展提供支持。
