The American Heart Association and Northwestern Medicine are teaming with Metra Wednesday morning to give riders a lesson on the new hands-only CPR method.
Instructors will also show how to use an automated external defibrillator. Early use of CPR and AEDs can help prevent someone from dying of a cardiac arrest.
After 6 a.m., demonstrators will be at Metra Millennium Station at Randolph and Michigan; Ogilvie Transportation Center; Metra stations in Evanston, Glenview, Lake Forest and Joliet; and a few other Metra stops.
