Location of defibrillation shock pad for cardiopulmonary resuscitation

When using a defibrillator, the electrode plate has two placement positions. One is called anteroposterior position, that is, an electrode piece is placed in the subscapular area of the back; The other piece was placed at the level of 3~4 intercostal space on the left edge of sternum. Some people think that this way has more current through the heart, so it needs less electricity and can reduce potential complications. This method is suitable for selective cardioversion. The other is to place an electrode between 2~3 ribs (the bottom of the heart) on the right edge of the sternum. The other piece is placed in the fifth intercostal space (apex) of the left axillary front line. This method is rapid and simple, and is suitable for emergency electric shock defibrillation. The distance between two electrode plates should not be less than l0cm. Usually, the traditional electrode plate (used for defibrillation) is placed at the top and bottom of the chest, which is the method mentioned later. If you use an AED to defibrillate, you just need to look directly at the tip of the electrode patch and then attach the electrode.
