Regulatory Responses to N95 Respirator Shortages
From the article:
Our recent posts have highlighted shortages in three COVID-19-related knowledge goods: testing, drugs (such as those needed to put patients on ventilators), and clinical trial information about effective treatments. This week we focus on the role of legal regulators in another critical shortage: N95 respirators, one of the key forms of personal protective equipment (PPE) for healthcare workers. We explain how N95 regulation, like COVID-19 testing, presented an interagency coordination problem. The FDA has successfully removed key regulatory hurdles—though the problem should have been anticipated earlier, and much more needs to be done to ensure an adequate supply.
What are N95 respirators?
N95 respirators are a specialized subset of face masks (here’s a handy NY Times explainer with photos). A normal surgical mask (what you see, for example, in a typical medical TV show) fits fairly loosely around the face; it blocks splashes and relatively large droplets, but not tiny particles. An N95 respirator, on the other hand, is relatively rigid rather than being flexible, and is designed to fit closely to the face and create a tight seal—tightly enough that the masks don’t work with certain beards (or for children). The “95” in N95 refers to the requirement that the mask block at least 95% of 0.3 micron particles (about a thousandth the width of a human hair). Both types of masks are meant to be single-use.
