How do ventilators work? | Alex Gendler

In the 16th century, physician Andreas Vesalius described how a suffocating animal could be kept alive by inserting a tube into its trachea and blowing air to inflate its lungs.

Alex Gendler explains the life-saving technology. [Directed by Artrake Studio, narrated by Addison Anderson].
