A new study says people cannot count on artificial intelligence voice assistants like Alexa and Siri for information on CPR during an emergency.

The study found that only 59% of voice assistant responses to questions about CPR provided information on cardiopulmonary resuscitation.

Only 33% gave instructions on how to perform the lifesaving technique.

Doctors say wrong information or delayed instruction can have a major impact on patients.

Brain damage can happen if CPR is not started within five minutes. Cardiac arrest can be fatal with CPR is not performed within eight minutes.

The American Heart Association urges everyone to take a CPR class.

They say if you are with someone who goes into cardiac arrest, the best thing to do is to call 911, put your phone on speaker and begin CPR chest compressions.
