Abstract

An external defibrillator can include a bump sensor for generating motion information and a bump detector for determining whether the external defibrillator has been subjected to a local bump event. The external defibrillator can transmit wirelessly a data signal encoding resuscitation event data to a second external defibrillator over a wireless communication link between the two devices.
