He rushed in and saw Chang Yue lying on the ground with one hand stretched out as if trying to grab something.
She was wearing pajamas, and the exposed skin of her hands and wrists was flushed, with red rashes visible. Because it was lying on its stomach, its growl was deep and hurried.
The System panel was so red that it looked like it was about to drip blood. The clear diagnosis made his heart sink — anaphylactic shock!
Even without the System's diagnosis, the three of them could tell that it was anaphylactic shock. Su Yun flipped Chang Yue's body over. He held the phone in his hand and dialed 120 while shouting, "Where's the razor you used for training?"
"Bedside table!" Su Yun's voice was hoarse. The veins in his neck were full, and the veins on his forehead were bulging. He used all his strength to say the words "bedside table".
As he spoke, he opened Chang Yue's mouth and took a quick look to confirm that there were no foreign bodies or large amounts of secretions.
He then placed one hand on Chang Yue's forehead, pinched her nostrils with his thumb and forefinger, and held her chin with his other hand to tilt her head back as far as possible to keep her airway open. Then, he took a deep breath and opened his mouth to seal Chang Yue's mouth.
As Chang Yue's chest rose 1.5 inches, Su Yun raised his head, took a deep breath, and performed artificial respiration.
After the second breath, he raised his head and loosened his grip on Chang Yue's nostrils. He turned his face to the side and put his ear between Chang Yue's mouth and nose.
A sharp whistle sounded.
Edema in the throat, convulsions in the respiratory tract, and respiratory obstruction.
Xie Yiren felt Chang Yue's pulse and immediately said in a hurry, "The pulse is slow and the blood pressure is estimated to be around 70."
The black hair on Su Yun's forehead fluttered as he stared at Chang Yue with bloodshot eyes. However, he did not say anything. Instead, he took another deep breath and performed artificial respiration according to the previous steps.
With the introduction of fresh oxygen, Chang Yue's lips, which had already begun to turn purplish, became slightly better.
Zheng Ren ran in after six rounds of CPR.
With a sterile blade in hand, he was ready to perform a tracheotomy at any time. Although there was no other equipment, this was the only thing they could do in an emergency. One more second was one more second. As long as the ambulance arrived, everything would be fine.
Fortunately, Su Yun usually trained in surgery at home. Although the equipment had bacteria, it was better than nothing.
Zheng Ren knelt on the left side of Chang Yue and stared at her System panel.
"Yiren, watch the elevator. The people from the emergency department will come up directly. Don't waste time," Zheng Ren said calmly.
Xie Yiren did not nod or speak. She turned around and ran. One of her slippers fell off, but she didn't notice.
Her fair feet stepped on the floor and she turned around to call for the elevator as fast as she could.
Chang Yue's blood pressure continued to drop, and as time went by, she began to sweat profusely and had a rapid pulse.
When the System Panel's red color reached its peak, it began to turn white.
At the same time, he used the index and middle fingers of his left hand to slide along the middle of the rib arch to the intersection of the two rib arches, searching for the notch below the sternum.
Then, he placed his index finger and middle finger horizontally above the incision of the sternum. The middle of the sternum above the index finger was the compression area.
He placed the base of his other hand close to his index finger and placed it on the middle and lower one-third of Chang Yue's sternum. He then removed the Locating Hand and overlapped the base of his palm on the back of his other hand so that his index finger was lifted off the chest wall.
He straightened his elbows and positioned his shoulders above Chang Yue's sternum. His shoulders and hands remained perpendicular to the center of Chang Yue's sternum. He pressed down hard with a depth of 5 to 6 centimeters and a frequency of 100 to 120 compressions per minute.
Zheng Ren could feel the tenacity of Chang Yue's sternum. It was constantly adjusting its strength to avoid any side injuries such as fractures. Zheng Ren, who had mastered the technique, no longer used brute force. His rescue technique was fundamentally different from before.
Time passed by bit by bit, and every second felt like a year had passed.
The color of Chang Yue's System panel did not continue to fade. With Zheng Ren and Su Yun's efforts, the basic blood oxygen supply was barely maintained.
Zheng Ren listened attentively as he performed chest compressions.
Other than Chang Yue's roars and Su Yun's heavy, panicked breathing, he was also listening to the sound of the first-aid ambulance.
'So f * cking slow!' Zheng Ren cursed in his heart. 'They should be here by now!'
At that moment, it was only 1 ′ 12 ″ since he made the call.
Zheng Ren's vision was a little pale. He suddenly felt his arms go numb and heavy.
He knew that with his physical fitness, this would not happen even after half an hour to an hour of chest compressions. He was too nervous, causing his body to secrete too much adrenaline and glucocorticoids.
It was like a novice doctor with stiff movements. He did not expect an experienced doctor like him to have this kind of moment.
Zheng Ren maintained a speed of at least 100 compressions per minute while taking a deep breath to calm himself down.
He glanced at Su Yun. Su Yun's face was pale and the corners of his lips were slightly trembling. He was also trying his best to suppress his emotions and not lose control.
As the first-aid ambulance sounded in the distance, Zheng Ren suddenly remembered something. The community hospital was just downstairs. If he went there directly to get the medicine, he could probably save one or two minutes …
Before he could regret his decision, Xie Yiren ran in. She was holding a first-aid kit and said loudly, "Adrenaline?"
"Epinephrine 0.5mg intravenously!" Zheng Ren was relieved when he saw that Xie Yiren was thinking ahead of him.
Xie Yiren opened the first-aid kit, injected a bottle of medicine, extracted the epinephrine, and disinfected it locally. The epinephrine was intravenously injected into Chang Yue's veins.
"Dexamethasone 10mg intravenously.
"Epinephrine 0.5mg intravenously again.
"Set up an intravenous channel and inject epinephrine," Zheng Ren said.
"Dopamine intravenous injection."
As footsteps came from the door, Zheng Ren yelled, "Did you bring salbutamol?"
"Boss Zheng, here!"
Tang Haitao ran in with the first-aid kit in one hand and the bottle of salbutamol spray in the other.
"Promethazine intravenous injection.
"Dexamethasone 10mg intravenous."
Zheng Ren observed the changes in Chang Yue's body, mainly using the color feedback on the System panel to decide the next rescue step.
The epinephrine and glucocorticoids entered her bloodstream and soon, the sound of Chang Yue's airway spasms subsided.
Her heart rate returned to normal and Zheng Ren removed his hand from her sternum.
He installed an ECG monitor. The readings showed that Chang Yue's blood pressure was slightly low at 80/40MHg, oxygen saturation 90%, and heart rate 122 beats per minute.
The ECG showed sinus tachycardia.
Fortunately … Zheng Ren breathed a sigh of relief when he saw that Chang Yue's breathing difficulties had further improved after the salbutamol spray.
"Stretcher."
