Interesting, I've been helping with this project to crowdsource ventilator manuals (
https://www.ifixit.com/News/36354/help-us-crowdsource-repair...) and as of last night Medtronic was saying they that they're "not providing [service] manuals to third parties but will provide manuals directly to the end users on request during this time to assist them in supporting their Medtronic ventilators." Good for them for changing their minds.
