Over a month, researchers found 15,234 messages on Twitter that included specific information about resuscitation and cardiac arrest,
said the study published in the journal Resuscitation.

According to the researchers, they found people using Twitter to send and receive a wide variety of information on CPR and cardiac
arrest, including their personal experiences, questions and current events.

Some researchers and organizations already use Twitter for public health matters, including tracking the 2009 H1N1 "swine flu" pandemic and finding the source of the Haitian cholera outbreak, the researchers said.

For the study, the researchers created a Twitter search for key terms, such as CPR, AED (automatic external defibrillators), resuscitation
and sudden death.
