Boss, you're awesome. " Seeing that Professor Rudolf Wagner had left, Su Yun came to Zheng Ren's side with a smile. He gave him a thumbs up and praised, "You're really good at goading me."
"I'm not goading you," Zheng Ren said calmly. "Tell me the truth. Don't make things difficult for Lil Fugui. I said it very simply before, so it's no wonder he has doubts. "
"Tsk, do you think he won't have any doubts after you say that?"
"I'll do my best. What else can I do? Do I have to barge in and perform surgery on Dr. Mehar? His heart can stop at any time during the surgery. If there's a chance, you have to be prepared for defibrillation, "Zheng Ren said.
"I'm one of the most professional experts in the study of myocardial electric currents. Don't worry, boss." Su Yun clenched his right fist and knocked on his left chest muscle.
Su Yun was quite confident in the field of cardiothoracic surgery.
"I know you're an expert, so I dare say that the success rate of the surgery is very high." Zheng Ren was a little tired. He slowly closed his eyes and said as if he was talking in his sleep, "I definitely don't trust them. If it were me, I wouldn't believe it either. That's why I can't cooperate with their circulating doctors. Once there's a cardiac arrest during the surgery, I'll have to rely on you. "
"Don't worry."
The conversation between the two of them ended there. Whatever they were talking about was nonsense and meaningless.
Zheng Ren closed his eyes to rest, but Su Yun was chatting on his phone in high spirits.
In the observation room, it was quiet. The doctor in charge was focused on monitoring his vital signs. The nurse occasionally entered the ward to change the intravenous nutrition for Dr. Mehar.
A few minutes later, a sharp and ear-piercing alarm suddenly rang out in the ward.
Without warning, almost all the machines roared at the top of their lungs. The doctor in the observation room outside jumped up immediately and rushed into the ward.
The screen in the observation room showed the values of all the instruments. Zheng Ren frowned and opened his eyes. He saw that the electrocardiogram had become a mess of waveforms.
The sinus rhythm no longer existed, and the electrocardiogram monitor showed rapid ventricular fibrillation.
Ventricular fibrillation was a rapid and weak contraction of the ventricular muscle or an uncoordinated rapid tremor.
The result was that the heart beat but no blood was pumped out, the heart sound and pulse disappeared, and the blood perfusion of the heart, brain, and other organs and surrounding tissues stopped. Argus syndrome broke out, and in the most severe cases, the patient would suddenly die within a few minutes, or even within a minute.
Simply put, Dr. Mehar's life had come to an end.
Su Yun jumped up as if he had pressed a spring. It was as if he was in the ICU of Sea City General Hospital. He wanted to rush in and participate in the rescue.
But in less than a second, he stopped in his tracks, and a mocking smile appeared on his handsome face.
"I forgot. I'm not at home." Su Yun said.
Zheng Ren did not say anything. He stared intently at the busy and orderly rescue operation behind the transparent glass.
A doctor was performing chest compressions while a nurse extracted the medication and injected it into the patient's vein as quickly as possible.
Another doctor quickly picked up the defibrillator and quickly and evenly applied the conductive paste on the defibrillator.
The upper edge of the STERNVM electrode plate was placed at the second intercostal space on the right side of the sternum, and the upper edge of the APEX electrode plate was placed at the fourth intercostal space on the left midline line.
All of his operations were extremely professional and fast.
External chest compressions were ineffective. Defibrillation was carried out immediately.
He could vaguely see Dr. Mehar's body tremble. The waveform displayed on the monitor was still that of ventricular fibrillation. There was no change.
Zheng Ren had forgotten that this was the ward of the Karolin Medical and Surgical Research Institute in Stockholm. He had also forgotten that the patient being rescued inside was Dr. Mehar.
In his opinion, he could only try to save a life through the ongoing rescue.
Compressions, medication, and defibrillation were all ineffective. All kinds of methods commonly used in the clinic had been used.
If he could not come over, the patient would die.
Zheng Ren quickly entered the System space and clicked on surgical training.
As usual, the simulation mannequin provided by the System was exactly the same as the recent patient's symptoms and physical condition.
The System was still very kind in this regard.
Zheng Ren quickly entered the System's operating theater and picked up the defibrillator according to the operating procedure.
At the standard position, Zheng Ren pressed the discharge button with both thumbs at the same time to defibrillate.
It was exactly as he had imagined. The defibrillation failed.
He injected beta blockers into the vein and changed the concentration of various drugs, but there was still no effect.
The heart rate of the simulation mannequin still showed ventricular fibrillation. A few minutes later, the electrocardiogram wave gradually turned into a straight line.
The simulation mannequin was dead.
Zheng Ren frowned as he stood in the System's operating theater and began to think.
Countless journals and documents appeared in his mind. All kinds of complicated cases provided Zheng Ren with a direction to think about.
In the case of the simulation mannequin, external chest compressions were definitely ineffective.
Zheng Ren had told the first-aid doctors in Sea City and Yuandian County about the rescue method for non-cardiogenic cardiac arrest.
As long as he had the strength, he could quickly solve the problem.
The standard preparation time before defibrillation was 20 seconds. He could not waste it.
However, the simulation mannequin's condition was that its vitality was drying up. The bioelectric current of the heart had weakened to a certain extent, which led to ventricular fibrillation.
This …
Perhaps it was really hopeless.
However, Zheng Ren was unwilling. Dr. Mehar could still perform the surgery. If he died just like that, he would not be able to live with it.
After thinking hard, an extremely bold idea suddenly appeared in Zheng Ren's mind.
Giving up on the drugs, Zheng Ren increased the direct current of the defibrillator from the standard 200J to 300J. The electrode plate was pressed on the simulation mannequin's body. Both thumbs pressed the discharge button at the same time to defibrillate.
There was a "bang" sound.
The simulation mannequin bounced up on the operating table and fell back down. The location of the electrode plates on both sides was a little charred, but the heart rate only recovered for a moment before ventricular fibrillation appeared again.
It was not enough, but the direction seemed to be right.
Zheng Ren frowned and increased the current of the defibrillator again.
400J！
However, this time, the simulation mannequin's heart stopped …
Zheng Ren cursed in his heart. The simulation mannequin was electrocuted by him!
Fortunately, this was the operating theater of the System. Fortunately, the object of his operation was the simulation mannequin and not the patient.
If he was wrong, he could start over. What a happy thing it was.
Zheng Ren seemed to have grasped a certain pattern. His mind began to calculate the relationship between the bioelectric current of the heart and the current intensity of the defibrillator.
A few similar articles also appeared.
After a quick calculation, Zheng Ren adjusted the power of the defibrillator to 330J and began the defibrillation.
With a bang, the simulation mannequin jumped on the operating table and then its body hit the operating table heavily.
Zheng Ren immediately turned around to look at the ECG monitor.
A brand new ECG wave appeared on the left side of the ECG monitor. The heart rate returned to sinus rhythm.
Although he was in the System space, Zheng Ren saw the waveform of the sinus rhythm. It was so beautiful.
It was done! That was it.
