Community and MDR

The FDA enforces science and data driven standards to promote and protect public health and safety. One of the ways they perform their job is by providing oversight of all products available to the public. One way they acheive "oversight" is through "post market surveillance," in other words monitoring how devices perform, with a special focus on potential or actual harms or injuries. In other words, FDA is deeply committed to the idea that "vendors" who create a device should know and report performance, safety and effectiveness data even when a vendor ceases to make or sell a device.

Get one day data out of Nightscout

Here's how to get one day of data out of Nightscout. The trick is in realizing that the field used to define the date is different between different data types, and that different data types are stored in different places. In addition, the API itself has interesting behaviors, for example to switch between tsv, csv, and json outputs, to perform regex based searches, and in some cases bugs to work around.

Mechanics of the search syntax. The API endpoints support a query string syntax used to compose queries.
