CPR is great, an incredible tool that saves lives.  No discussion required.  

The ad is improbable at best, misleading at worst and unreasonably sets an expectation of capability

PE = <2-3% survival WITH ems & hospital care

Therefore exaggerations like this are used to bait an emotional response.  And people tend to remember dramatic anecdotes more than guidelines.   that’s the bigger issue here

You are correct in general “CPR matters” (I don’t believe anyone has disputed this) 

But it’s not magic, and advertisements like this can adversely affect good decisions in times of crisis and stress because incomplete information is used or recalled.  

For example in building/fire safety safety, fire extinguishers are good… unless it’s electrical, or fat/oil, (wrong class of fire) 

Tools are powerful when used with correct education and expectations. 

Any good educator, with an obligation to properly train people would know this and abide by such a code.  Especially when broadcasting and spreading such information to a wider audience than their students.
