Each year, almost 300,000 people suffer out-of-hospital cardiac arrests in the United States. Survival rates from these events tend to be extremely low. However, research has shown that hands-only bystander CPR can triple survival from out-of-hospital cardiac arrest.  The problem is that bystanders that witness a cardiac arrest only attempt CPR about 26% of the time- and getting more people trained and comfortable is the key to saving lives.  Ben Bobrow, M.D. (our EMS Medical Director) was the lead author and Vatsal Chikani and Paula R. Brazil co-wrote a new study published this week in Circulation found that even an ultra-brief (60 second) training video people did much better.  This finding has enormous public health implications because now we know that even brief interventions like viewing a training video can be effective training tools for bystanders.
