    He Xiangyu looked back and saw that while the junior sister was rescuing people, someone actually tried to pull the sleeve of the junior junior sister, warning loudly: "Doctors are saving people, don't get in the way, stand aside!"

    Several people immediately obeyed the order and retreated obediently.

    Liu Jingyun couldn't hold down the young man's bleeding area with a towel, and the blood continued to flow out. Knowing that she couldn't handle it with her own strength, she made a judgment and said to the second junior sister: "Go and perform heart compressions on Yingying and ask her to come over.  !¡±

    Turning around and running, He Xiangyu rolled up her sleeves and came to the side of the junior sister. She pushed the junior sister away and rushed forward to apply pressure. She called to the junior sister: "You go to the senior sister, I'll do it here!"

    "Second senior sister, you have to keep pressing on her, she has a cardiac arrest, there is a chance -" Xie Wanying said to the senior sister.

    "I know, I won't stop until you tell me to stop!" He Xiangyu gathered her strength and planned to press 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, came to the senior sister and asked, "What's going on?"

    "The bleeding can't be stopped!" Liu Jingyun pressed the patient's bleeding area hard until her hands trembled and her voice trembled.

    "Move away a little and let me see where the bleeding is." Xie Wanying said.

    Liu Jingyun was not very confident. When she slowly removed her hand and towel, she saw that the wound was bloody and bloody, and she couldn't help but cover it with a towel.

    People around me covered their faces and eyes, not daring to look at it: It was too scary!

    Only the surgeon would dare to look at it at this time.

    ???????????????????????????????????????????.  Violent injuries to the head caused by impact force may be called traumatic brain injury or craniocerebral trauma or craniocerebral injury.  Craniocerebral injury is divided into scalp injury, skull injury or brain injury within the skull. Now, whether this patient has one of these injuries or a combination of the three injuries requires preliminary identification.

    The patient¡¯s pupillary reflex is present and no abnormalities are found. It can be initially determined that there is no intracranial brain damage.  The human skull is hard and the destructive force is not very terrible, so it is impossible to cause skull damage.  So, it's probably just scalp damage.

    Don¡¯t underestimate scalp injuries, because the human scalp is rich in blood vessels, and the amount of bleeding will suddenly become large and cause the patient to go into shock.

    The patient¡¯s blood pressure dropped, and his complexion and lips turned a little white.  You need to stop the bleeding immediately.  It's just that hemostasis on the scalp is different from hemostasis on the skin in other parts of the body.

    The scalp is divided into five layers. Scalp injury and bleeding are caused by damage to the subcutaneous tissue layer rather than the skin layer.  The rich blood vessels in the human scalp refer to the numerous blood vessels separated by fibers in the subcutaneous tissue layer.  When the scalp is damaged, the blood vessels under the skin cannot contract on their own, resulting in profuse bleeding.  If compression cannot stop the bleeding, in addition to suturing, injection of drugs is required to shrink the blood vessels in the scalp to stop the bleeding.

    ¡°Here we go, there¡¯s a piece of yarn!¡± The store manager found the first aid box and brought it over. After opening it, there was finally a piece of yarn.

    Xie Wanying asked the senior sister to cover the wound with a piece of gauze. After determining the scope of the wound with her eyes, she pressed her fingers on the scalp around the wound to stop the bleeding, so as to block the blood supply.

    A group of people around him watched with bated breath, and finally it seemed that the blood had stopped pouring out.

    "Gauze pieces and bandages." Xie Wanying gave the instruction.

    The person next to her hurriedly handed her the tools.  Use the gauze piece to continue to press the area where her fingers are pressing, and then use a bandage for compression and fixation.  (Remember the website address: www.hlnovel.com
