Medtronic is a major manufacturer. Release appears to be detailed and complete. Open license is time-limited but good for the pandemic. May be hard to build outside of major manufacturing. Costs of bill of materials and supply chain currently unknown. Thanks to Medtronic for doing this!

Pressure RegulationNew
Bread boarding phase, look for documents (README minimal), some presure/volume testing. Not sure how the alarms work, but they have pressure sensor control. Exceptionally easy to use physical controls. Requires pressure sources. Valved solution produces some jitter in pressure wave; I don't know if that is clinically a problem or not.
