When someone experiences sudden cardiac arrest (SCA) in a public place, the most critical actions a bystander can take are to call 9-1-1, and deliver cardio-pulmonary resuscitation (CPR) to provide blood flow to the heart and brain.
If that proves ineffective in starting the victim breathing before emergency medical help arrives, and there is a AED (automatic external defibrillator) such as a MIKEY available, a trained target responder can use this machine to deliver a potentially life-saving shock.
MIKEYs are remarkably easy and efficient to use. It’s a matter of opening the case and following the instructions delivered through voice prompts. The operator removes the patient’s clothing in the chest area, attaches the adhesive pads or electrodes to the chest, and stands back while the MIKEY records and analyzes the heart rhythms. The MIKEY will tell the rescuer when and if to push the button to deliver a shock, and provides audio prompts for the proper steps.
Sometimes, CPR is required for a few minutes after defibrillation to help the patient’s heart resume an a more normal rhythm.
When a MIKEY is placed in a public place, training is provided to key personnel in the correct use of the AED.
