Whether conscious, whether there are blood, sediment, phlegm and other foreign bodies in the mouth and nose.

2. Whether there is hemothorax and pneumothorax.

3. There is no fracture in the front and back chest.

4. Is it difficult to breathe with broken ribs?

Second, judgment.

1. Simple fracture: only rib fracture, no wound in chest, local pain, shortness of breath and hematoma in skin.

2. Multiple fractures: multiple rib fractures, chest subsidence when begging. Multiple chest wounds, severe pain, and difficulty breathing. This kind of fracture is often complicated with hemothorax and pneumothorax. If it is not rescued in time, it will soon die.

Third, first aid.

1. When a simple fracture occurs, the local area shall be covered with multiple layers of clean cloth, wool or sterile gauze, and pressure shall be applied to bind it.

2. Multiple fractures can be fixed around the radius of chest cavity with wide cloth or wide glue. Prevent further injuries and seek medical treatment immediately.

3. Oxygen inhalation when conditions permit.

4. If there is pneumothorax, send it immediately after first aid.
