Cardio Pulmonary Resuscitation
This is hands down a quick and effective lesson in the basics of the how the heart works. What they explain in this little 3 minute video is most likely going to impact every person in some type of way, when we know so little about the human heart.
I always say , what better time to learn about the heart then while attending a CPR class, please take 3 minutes out of your day to get a little bit of knowledge that will last your entire lifetime.
