Description
Introduction: Due to the COVID-19 crisis or any other mass casualty situation it might be necessary to give
artificial ventilation to many affected patients. Contrarily, the worldwide availability of emergency ventilators is
still a shortage, especially in developing countries.
Methods: Modes of artificial ventilation were compared and the most safe, easy to use, and lung protecting
principle was optimized to fit all requirements of both emergency ventilation and cost-effective mass production.
Results: The presented research results describe a simplified device for a pressure-controlled ventilation which
works without electricity according to a known principle. Just pressurized gas and a patient connection is
required. The device enables the control of basic ventilator parameters such as peak inspiratory pressure, positive
end-expiratory pressure and the ventilation frequency. Further, the device is semiadaptive to the patient’s lung
stiffness and automatically maintains minute volume through frequency adjustment. The machine can be
manufactured by turning, milling and drilling and needs purchased components with costs less than 100 USD. A
sterilization and thus a reuse is possible.
Discussion: The presented development does not describe a ready-to-purchase ventilator, it rather outlines a
refined working principle for emergency ventilation and its easiest methods of production with a minimum of
requirements. The presented research aims on providing an open-source guideline for production of an emergency
ventilator using worldwide available methods and thus should inspire local researchers to do a reverse
engineering and eventually to put it into operation following country-specific regulations. For long-term
ventilation exceeding emergency purposes, a monitoring of alarms for disconnection and violation of desired
ventilator parameters should be established. The ventilator is limited to a fixed ratio between PIP and PEEP.
Moreover, the ventilation frequency depends on two parameters, which needs some training. Nevertheless, the
ventilator provides basic features to enable an emergency ventilation with minimal prerequisites.
