Looking this up led me to Open Pediatrics, a lovely idea:

A video going into more of the detail, on reflection the big idea seems to be the air pressure oscillations

Tangential, Openpediatrics seems like a great initiative, are there any other such resources for other medical fields?

There is the FOAM movement (Free and open acces meducation - https://lifeinthefastlane.com/foam/) but I bet there's many more out there.

It feels like there is some foundation for medicine to evolve like software evolved, where there is more and more open source knowledge to build upon, democratizing and lowering the cost of access to that knowledge.
