Technology Overview
OHSU # 2889 — CRISIS ventilator
Summary
Researchers at OHSU have designed a novel ventilator system that 1) can be produced quickly, 2) has minimal operational requirements allowing for use in disaster settings and field facilities, and 3) has the capacity to provide both standard and severe respiratory distress ventilation support.
Technology Overview
The COVID-19 pandemic revealed flaws in the stockpiling and distribution of ventilators, demonstrating a need for more rapidly available and inexpensive alternatives. In addition, less expensive ventilators that can be utilized with limited resources can be critical tools for disaster response situations and field settings.
The emergency CRISIS ventilator developed at OHSU device by Dr. Albert Chi and colleagues has the following features:
- Gas-powered with no requirements for electricity.
- Compatible with either O2 tanks or standard hospital 50psi O2 wall supply.
- Small in size and less than one pound in weight, allowing for quick portability.
- Rapidly producible for immediate deployment in crisis areas.
- 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.
- Validated ability to ventilate and oxygenate in a porcine 24-h proof-of-concept study.
