After Zheng Ren rushed in, he saw Chang Yue lying on the ground with one hand forward, as if he wanted to grab something.

She was wearing pajamas, her hands and wrists exposed outside were flushed, and she could see red maculopapular rashes. Because of her prone, the wheezing sound was low and rapid.

The system panel was so red that it was about to drip blood. A bright diagnosis on it made Zheng Ren's heart sink to the bottom - allergic shock!

Without systematic diagnosis, the three people present could tell that they had allergic shock when they caught their eyes. Su Yun turned Chang Yue's body over, Zheng Ren held the phone in his hand, and while calling 120 for first aid, he shouted: "Where is the blade you used for training?"

"Bedside table!" Su Yun's voice was hoarse, his neck veins were filled, and his forehead was blue veins were exposed. He tried his best to say the three words "Bedside table".

While he said, he opened Chang Yue's mouth and took a brief look to confirm that there were no foreign objects or a large amount of secretions.

Then he placed one hand on Chang Yue's forehead, pinched her nostril with his thumb and index finger, held the chin with the other hand and leaned back as much as possible, keeping the airway open, then took a deep breath and opened his mouth to close the surrounding Chang Yue's mouth.

As Chang Yue raised his chest, after 1.5″, Su Yun raised his head, took a deep breath of oxygen, and then took another artificial respiration.

After the second breath, he raised his head and relaxed his hand holding Chang Yue's nostrils, turned his face to the side, and put his ears between Chang Yue's mouth and nose.

A sharp whistle sound came.

Laryngeal edema, respiratory spasm, and impeded breathing.

Xie Yiren touched Chang Yue's pulse and immediately said quickly: "The pulse is thin and fast, and the blood pressure is estimated to be around 70."

Su Yun's black hair fluttered slightly, his eyes stared at Chang Yue tightly, and his bloodshots rose. However, he did not speak, and had already taken deep breaths again, and then he performed artificial respiration according to the previous steps.

As fresh oxygen enters, Chang Yue has begun to have a little cyanotic lips color relieved slightly.

After 6 artificial respirations, Zheng Ren ran in.

The sterile blade is in your hand and you are ready to perform tracheotomy at any time. Although there are no other equipment, you can only do this in an emergency. It can be maintained for one second for one second, as long as the ambulance arrives.

Fortunately, Su Yun usually trains surgery at home. Although the equipment has bacteria, it is better than none.

Zheng Ren knelt on the left side of Chang Yue's body, staring at her system panel.

"Yiren, look at the elevator, the emergency department comes up directly, don't waste time." Zheng Ren said calmly.

Xie Yiren did not nod or speak, but turned around and ran away. One of her slippers fell off, but she didn't notice it.

Her fair little feet stepped on the floor and then turned around and disappeared. She called the elevator as fast as possible.

Chang Yue's blood pressure continued to drop, and he developed symptoms of sweating profusely and rapid pulse over time.

When the system panel reaches its peak, it begins to turn white.

At the same time, Zheng Ren used his left hand to slide along the rib arch to the middle to the intersection of the rib arch, and found the substernum notch.

Then place the indicator and middle finger horizontally above the notch below the sternum, and the center of the sternum above the indicator is the compression area.

He placed the palm of the other hand close to the pointer in Chang Yue's sternum, and took off the positioning hand, overlapped the root of the palm on the back of the other hand, so that the fingers were raised and removed from the chest wall.

The elbow joints are straightened, Zheng Ren's shoulders are in the middle of Chang Yue's sternum, and the shoulders and hands are kept vertical and pressed downwards. The downward depth is 5 to 6 cm, and the pressing frequency is 100 to 120 times per minute.

Zheng Ren could feel the toughness of Chang Yue's sternum and constantly made subtle power adjustments to avoid causing side injuries such as sternum fractures. Zheng Ren, who has mastered the feel, no longer violently presses, and the rescue method is qualitatively different from before.

Time passes by bit by bit, and every second is as hard as a year has passed.

The color of Changyue system panel has not continued to fade. With the efforts of Zheng Ren and Su Yun, the most basic blood oxygen supply is barely maintained.

Zheng Ren listened while doing heart pressure outside the chest.

In addition to the wheezing between Chang Yue's mouth and nose, Su Yun's heavy and panicked breathing, he was listening to the sound of the 120 ambulance.

It's so fucking slow! Zheng Ren cursed viciously in his heart, it's time to run over!

At this time, it was only 1′12″ before he called.

Zheng Ren felt that the vision in front of him was a little pale, and he suddenly felt his arms were sore and heavy.

He knew that with his physical fitness, if he did external heart compression, this would not happen for half an hour to an hour. It was too nervous, which caused the body to secrete excessive adrenaline and glucocorticoids.

Just like a novice doctor on stage, his movements were stiff, I didn’t expect that my old driver would have the same time now.

While maintaining the external heart pressure speed of at least 100 times per minute, Zheng Ren took a deep breath of air to calm himself down.

He glanced at Su Yun, who looked pale, his lips trembled slightly, and he was barely suppressing his emotions and not losing control.

As the sound of the 120 ambulance in the distance sounded, Zheng Ren suddenly remembered something in his heart. The community hospital was downstairs. If he went directly to the side to get the rescue medicine, he should be 1 minute or 2 minutes earlier...

Before he could regret it, Xie Yiren had already run in. She held the first aid kit in her hand and said loudly, "Adrenaline?"

"Adrenaline 0.5mg is quietly pushed!" Zheng Ren felt relieved when he thought of his advance.

Xie Yiren opened the first aid box, sprayed the medicine bottle, took out the adrenaline, disinfected it locally, and hit the nail on the head, and the adrenaline was pushed into Chang Yue's vein.

"Dexamethasone 10mg, intravenous injection."

"Adrenaline 0.5 mg is given again intravenously."

"Indwelling the venous passage and the adrenaline is still." Zheng Ren said.

"Dopamine, static push."

As footsteps came from the door, Zheng Ren shouted loudly: "Did you bring salbutamol?"

"Boss Zheng, here!"

Tang Haitao trotted in, carrying an emergency rescue box in one hand and a bottle of salbutamol spray in the other.

“Promethazine, intramuscular injection.”

“Dexamethasone, 10 mg, intravenous.”

Zheng Ren observed Chang Yue's changes, mainly by deciding the next rescue measures through the color feedback on the system panel.

Adrenaline and glucocorticoids enter the blood circulation, and soon the sound of Chang Yue's airway spasm becomes much lighter.

The heart recovered from its autonomous heart rate, and Zheng Ren took his hand away from her sternum.

Install ECG monitoring, and the values ​​show that Chang Yue’s blood pressure is slightly lower, 80/40mmhg, blood oxygen saturation is 90%, and heart rate is 122 beats/min.

Electrocardiogram is sinus tachycardia.

Fortunately... I sprayed Chang Yue with aphrodisiac. Seeing that her breathing difficulties were further relieved, Zheng Ren breathed a long sigh.

"stretcher."
