Abstract

This article details the design of an open source emergency gentle ventilator (gentle-vent) framework that can be used in periods of scarcity. Although it is not a medical device, the system utilizes a wide range of commonly-available components that are combined using basic electronics skills to achieve the desired performance. The main function of the gentle-vent is to generate a calibrated pressure wave at the pump to provide support to the patient's breathing. Each gentle-vent permutation was tested using a DIY manometer as it would be utilized in the field in low-resource settings and validated with an open source VentMon. The most rudimentary implementation costs less than $40.

摘要

本文详细介绍了一种可在资源稀缺时期使用的开源简易呼吸机（gentle-vent）框架的设计。虽然它不是医疗设备，但该系统利用了多种常见组件，通过基本的电子技能将这些组件组合起来，以实现所需的性能。gentle-vent的主要功能是在泵处产生校准压力波，为患者的呼吸提供支持。每个gentle-vent变体都使用了一个自制压力计进行测试，因为它将在资源匮乏的现场环境中使用，并通过开源的VentMon进行验证。最基本的实施方案成本不到40美元。
