He Xiangyu looked back and saw that the junior sister was saving someone. Someone wanted to pull the junior sister's sleeve, and shouted: "Doctor to save people, don't interfere, stand aside!"

Several people immediately obeyed the order and retreated obediently.

Liu Jingyun couldn't hold the young man's bleeding area with a towel, and the blood continued to flow out. He knew that his strength could not be handled, so he made a judgment and said to the second junior sister: "You go and do a heart pressure on Yingying and let her come over.

!”

Turning around and running, He Xiangyu rolled up his sleeves and came to the younger sister next to him and pushed him away, rushing up and pressing him, calling the younger sister: "You go to the elder sister's place, I'll come here!"

"Second Senior Sister, you have to keep pressing her. She has a cardiac arrest and has a chance-" Xie Wanying said to her senior sister.

"I know, I won't stop if you don't call me!" He Xiangyu tried hard and planned to press it desperately, pressing it on the old man's chest hundreds of times a minute.

The patient was handed over to the second senior sister first. Xie Wanying ran back and went to the senior sister to ask, "What's the situation?"

"The bleeding cannot be stopped!" Liu Jingyun pressed the patient's bleeding area hard, and his hands were about to tremble, and his voice shivered.

"You move a little bit and I'll see where the bleeding is." Xie Wanying said.

Liu Jingyun was not very confident. The moment she slowly moved her hands and towel away, the wound was exposed, and the bloody and bloody wound was bleeding, making her unable to help but take the towel up.

People around him covered their faces and eyes, but they didn't dare to look at them: It was so scary!

Only surgeons dare to see this time.

Let the senior sister move her hand away, Xie Wanying carefully and in detail, and must first distinguish what the wound is. The head is subject to violent damage, which can be called brain trauma, trauma or trauma.

.Crain and brain injury are divided into scalp injuries, skull injuries or brain injuries in the skull. Now this patient is one of them or both of them needs to be identified.

The patient has pupil reflexes and no abnormalities are found. It can be preliminarily determined that there is no brain injury in the skull. The person's skull is hard, not a very terrible destructive force, and it is impossible to cause skull damage. Therefore, it is likely that it is just a scalp damage.

Don’t underestimate scalp damage, because the scalp has abundant blood vessels and the bleeding will suddenly be very large, which will cause the patient to fall into shock.

The patient's blood pressure has decreased, showing symptoms of a slight white lips. It is true that he should stop bleeding immediately. It is just that stopping the scalp bleeding is different from other parts of the skin.

The scalp is divided into five layers. Scalp damage and bleeding is damaged in the subcutaneous tissue layer rather than the skin layer. The rich blood vessels of the human scalp refer to the many blood vessels that are separated by fibers in the subcutaneous tissue layer. The subcutaneous blood vessels that are damaged in the scalp cannot contract by themselves.

So there is a lot of bleeding. If compression cannot stop bleeding, in addition to suture, medication is required to shrink the scalp blood vessels to stop bleeding.

"Here, there are yarn blocks!" The manager found the first aid box and brought it over. After opening it, there were finally yarn blocks.

Xie Wanying asked her senior sister to take a piece of gauze to cover the wound. After her fingers determined the wound range on her eyes, she pressed her scalp around the wound to stop bleeding, so that she could block blood circulation.

A group of people around him held their breath and looked at it, and finally it seemed that blood was not constantly coming out.

"Garland blocks and bandages." Xie Wanying gave an instruction.
