CRISIS Ventilator

Case ID:
Web Published:


Ventilator shortages are occurring worldwide in the face of the COVID-19 pandemic, and there is an urgent need for rapidly deployable alternatives. Researchers at OHSU have designed a novel ventilator system that 1) can be produced quickly, 2) has minimal operational requirements allowing for use even in austere temporary facilities, and 3) has the capacity to provide both standard and severe respiratory distress ventilation support.


The worldwide pandemic of COVIDÔÇÉ19, a respiratory disease caused by the novel coronavirus, is a monumental public health threat and it is estimated that 50% of the ICU admitted patients would require ventilatory support, often for prolonged durations. Ventilators are critical for COVID-19 treatment as they provide a controlled delivery of gases to support a patient in respiratory failure until the patient’s own immune system can mount a defense to the virus.

The OHSU device from Dr. Albert Chi and colleagues has the following features:

•       Requires no electricity, has no electronics;

•       Uses either O2 tanks or standard hospital 50psi O2 wall supply;

•       Small in size and weighing less than one pound;

•       Can be produced rapidly and immediately deployed in crisis areas;

•       Can be replicated anywhere in the world;

•       Sterilizable by autoclave or chemical immersion for multiple uses;

•       Capable of numerous ventilator settings to treat varying degrees of respiratory failure and size (normal lung, poor functioning lung, pediatric lung);

•       Durable;

•       Has the capacity to treat patients with progressive acute respiratory distress syndrome (ARDS) observed with COVID-19 as well as standard ventilatory support. This is achieved by a flow-driven device with an adjustable valve, preliminary testing with this device demonstrated its ability to achieve high positive end expiratory pressure (PEEP) and respiratory frequency needed for ARDS treatment.
