The simple answer is, 'No,' according to research done at the Medical College of Wisconsin in Milwaukee. According to the study, recently reported by Reuters, in a random sample of YouTube videos dealing with CPR instruction, a little over half were posted by individuals with no health credentials. The other half were posted by private groups, businesses, and individuals with some kind of health credential. But while most of these videos gave accurate information, the information, according to the Wisconsin researchers was not thorough.
Most videos on YouTube dealing with CPR either incorrectly described the rate of CPR chest compressions or did not cover that detail at all. And over half didn't show viewers how deep the chest compressions should be.
The researchers found the best source for CPR information on YouTube was at the Red Cross' official channel.
In an emergency situation, having knowledge about how to perform CPR is important. The first four minutes in an emergency cardiac arrest situation are the critical moments when brain and permanent tissue damage can be avoided. Life and death hang in the balance, and often emergency medical personnel have not yet arrived.
No emergency medical supplies have been invented to resurrect the dead. The importance of CPR in assisting first responders in emergency situations can't be stressed enough. Using YouTube is a good way to gain familiarity with the process, but there is no substitute for CPR certification and training.
