It’s a good thing that they changed the CPR to chest compressions only, (To the tune of “Stayin’ Alive” just by coincidence) – With this virus going around, and the general paranoia about all things hygiene that will linger for years after for sure, CPR is scary.
CPR contraptions such as this antique device would not be helpful. This one looks downright ineffective from the get-go. It looks like a vacuum cleaner attachment.
