AimCurrent pricing of commercial mechanical ventilators in low-/middle-income countries (LMICs) markedly restricts their availability, and consequently a considerable number of patients with acute/chronic respiratory failure cannot be adequately treated. Our aim was to design and test an affordable and easy-to-build noninvasive bilevel pressure ventilator to allow a reduction in the serious shortage of ventilators in LMICs.
方法呼吸机是使用现成的材料建造的via电子商务基于高压鼓风机,两个压力传感器和一个带有数字显示的Arduino纳米控制器(总零售成本<75 USD),提供了免费复制的施工详细信息。对呼吸机进行了评估,并将其与市售设备(Lumis 150呼吸机; Resmed; Resmed,美国加利福尼亚州,美国加利福尼亚州)进行了比较:1)使用主动呼吸的患者模拟器模仿一系列阻塞性/限制性疾病;b)在12名健康志愿者中,穿着高气道阻力和胸腔/腹部带,以模仿阻塞性/限制性患者。
结果设计的呼吸机提供了高达20/10 cmh的灵感/呼气压力2O, respectively, with no faulty triggering or cycling; both in the bench test and in volunteers. The breathing difficulty score rated (1–10 scale) by the loaded breathing subjects was significantly (p<0.005) decreased from 5.45±1.68 without support to 2.83±1.66 when using the prototype ventilator, which showed no difference with the commercial device (2.80±1.48; p=1.000).
结论的low-cost, easy-to-build noninvasive ventilator performs similarly to a high-quality commercial device, with its open-source hardware description, which will allow for free replication and use in LMICs, facilitating application of this life-saving therapy to patients who otherwise could not be treated.
