First responders say there is a device that increases the chances that a patient in cardiac arrest will survive.

First responders say the Lucas Device keeps compressions going during CPR, freeing them up for advanced life support. The device continues to perform CPR even while first responders are moving the patient.

Credit for cardiac saves is shared, first responders say. Lucas increases chance of survival, but so do bystanders who get chest compressions started before first responders get there. First responders say it is important to start chest compressions immediately.
