This is a work in progress of <a href="https://www.pubinv.org">Public Invention</a>.
<p>
This is a tester tool for open-source ventilators.
It uses the <a href="https://github.com/PubInv/respiration-data-standard">PIRDS data format</a>.
<p>
The basic operation is receive data from web server specified in the URL above.
Probably for now that will be the VentMon Python web server that
listens on a serial port for the VentMon device or any other
device that streams PIRDS events.
