Today many people confuse TENS with electrical muscle stimulation (EMS). EMS and TENS devices look similar, with both using long electric lead wires and electrodes. TENS is for blocking pain, where EMS is for stimulating muscles.
An AED will not allow an electrical shock to be delivered if the device does not detect the proper cardiac arrest condition. AEDâs can be used on anyone over one year old. The AHA recommends the use of pediatric attenuated pads for a child aged 1-8 years. If pediatric AED pads are not available for a child cardiac arrest patient, the AHA recommends use of the AED adult defibrillation pads.
