DIY ventilator makers may request that their product be added to the Emergency Use Authorization (EUA) that FDA issued on March 24, 2020, to legally market the product in the U.S. Instructions on how to do so, and the criteria for ventilator safety, performance and labeling, may be found in the Letter of Authorization and Appendix A for the EUA related to ventilators, anesthesia gas machines modified for use as ventilators, positive pressure breathing devices modified for use as ventilators, ventilator tubing connectors, and ventilator accessories.
