Surgical Masks

The Surgical Masks working group has identified design inputs and criteria based on FDA standards as well as clinical input from front line workers and other health care providers. This criteria and clinical input is also being applied to the design of an “ideal” surgical mask to improve upon the current design. Additionally, the working group developed a system for clinical evaluation and feedback of PPE designed by industry collaborators.
