But is it correct to say in the following way?
Judging by the Google results below, I think not. With the context given, and taking into account TimLA's and Hermione's advice, I'd suggest:
[Name of certificate holder]. CPR certification from [name of certifying institution].
A version which is slightly closer to yours (post #4) but probably further from actual practice would be:
[Name of certificate holder] with CPR certification from [name of certifying institution].
