The method of extrathoracic cardiac compression

summary

I believe that many people don't understand the method of extrathoracic heart compression, so I went to understand a lot of this knowledge, briefly describe the method of extrathoracic heart compression, many people want to understand it, now I will share with you the method of extrathoracic heart compression

The method of extrathoracic cardiac compression

The first step is to lay the patient on his back, untie his collar, and open the airway by raising his chin. The rescuer is on the left side of the patient. The pressing position was at the junction of 1 / 3 of middle sternum and 1 / 3 of lower sternum. 　　

In the second step, the left palm root is close to the pressing area, and the right palm root is overlapped on the back of the left hand, so that all fingers are separated from the chest wall. The rescuer's arms should be straight, his shoulders should be right above the patient's chest, and he should press down with force vertically. The pressing should be stable, regular, uninterrupted, without impact and violent pressure. The time of pressing and relaxing should be roughly equal. 　

The third step, adults 60-100 times per minute. Compression depth: adult sternal depression 3-5cm. Mouth to mouth artificial respiration should be carried out at the same time of chest compression. Do not press the heart too hard to prevent rib fracture or other visceral injury. If it is found that the patient's face turns ruddy, his breathing and heartbeat recover, his pulse can be felt, and his pupil retraction is normal, the rescue is successful

matters needing attention

I see. To briefly describe the method of heart compression outside the chest, we should pay attention to: before pressing, keep the respiratory tract unobstructed, keep the pillow removed, lie flat, chin up. Second, we should pay attention to the 1 / 3 junction of the lower edge of sternum when pressing. Press with both arms straight and vertically.
