<h4>Chapter 623: If He Was Wrong, He Could Start Over</h4>


    “Boss, you’re awesome.” Su Yun looked at Professor Rudolf Wagner leave and came to Zheng Ren’s side with a smile. He gave him a thumbs up and praised him, “You’re really good at provoking people.”


    “I wasn’t trying to do such a thing,” Zheng Ren said indifferently. “I just told the truth since I didn’t want to make things difficult for Lil Fugui. What I said before was very simple. No wonder he has doubts.”


    “Tsk. Do you think that by saying that, he won’t have any doubts?”


    “I’ll do my best. What else can I do? Do I have to barge in and directly perform surgery on Dr. Mehar? When the surgery is der, the heart can stop at any time. If there’s a chance that might happen, you have to be prepared for defibrition,” Zheng Ren said.


    “I’m one of the most professional experts in the field of cardiac surgery. Don’t worry, boss.” Su Yun clenched his right hand into a fist and knocked on his left pectoral, making loud banging sounds.


    Su Yun was quite confident in his specialty in cardiac surgery.


    “I know you’re an expert, so I dare say that the sess rate of the surgery is very high.” Zheng Ren was a little tired. He slowly closed his eyes as if he was talking in his sleep, saying, “I definitely don’t trust the people here. If it were me, I wouldn’t believe it either. That’s why I can’t cooperate with the doctors around. Once there’s a sudden cardiac arrest during the surgery, I’ll have to rely on you.”


    “Don’t worry.”


    The conversation between the two ended there. Whatever they were saying was nonsense and meaningless.


    Zheng Ren closed his eyes to rest, while Su Yun was chatting on his cellphone in high spirits.


    It was quiet in the clinical decision unit. The doctors who were looking after him were focused on monitoring his vital signs. The nurses asionally went into the ward to change the intravenous nutrition medication for Dr. Mehar.


    A few minutester, a sharp and ear-piercing rm suddenly sounded in the ward.


    Without any warning, almost all the machines were screaming at the top of their lungs. The doctor in the clinical decision unit jumped up immediately and rushed into the ward.


    The screen in the clinical decision unit had all the values being ryed by the machines. Zheng Ren frowned and opened his eyes. He saw that the electrocardiogram had be a mess of waves.


    Sinus rhythm no longer existed. The electrocardiogram monitor showed rapid ventricr fibrition.


    Ventricr fibrition was a rapid and weak contraction of the ventricr muscle or an uncoordinated rapid and chaotic tremor.


    The result was that the heart would beat but no longer pumped blood out. The heart sound and pulse disappeared. As a result, blood perfusion stopped for the heart, brain, and other organs, as well as the surrounding tissue. It was the onset of A-S syndrome. The most serious patient would just suddenly die within a few minutes or even a minute itself.


    Simply put, Dr. Mehar’s life hade to an end.


    Su Yun jumped up as if he had pressed a spring. It was as if he was back in Sea City General Hospital’s emergency department, trying to rush in to participate in the rescue.


    However, in less than a second, he stopped as a smile appeared on his handsome face.


    “I forgot, I’m not at home,” Su Yun said.


    Zheng Ren did not say anything, staring at the busy and orderly rescue behind the transparent ss.


    A doctor was performing chestpressions. The nurse took the medicine and injected it into the patient’s vein as fast as she could.


    Another doctor quickly picked up the defibritor and quickly and evenly applied the conductive paste on the defibritor.


    The upper edge of the STERNVM electrode te was ced between the second ribs on the right side of the sternum; the upper edge of the APEX electrode te was ced between the fourth ribs on the left midaxiry line.


    Everything was done very professionally and quickly.


    The external chest cardiacpression was ineffective, and the side was immediately defibrited.


    Dr. Mehar’s body was trembling slightly. The waveform disyed on the monitor was still the same as the ventricr fibrition waveform. There were no changes in the situation.


    Zheng Ren forgot that this was a ward at the Karolin Medical and Surgical Research Institute in Stockholm. He also forgot that the patient who was being treated inside was Dr. Mehar.


    In his opinion, the only thing he could do was to try his best to save a life.


    Compressions, drugs, and defibrition were all ineffective. All kinds of methods and methodsmonly used in the clinic were being used.


    If he could not get through, the patient would die.


    Zheng Ren quickly entered the System’s space and selected the surgical training.


    As usual, the simtion mannequin provided by the system was exactly the same as the patient’s recent symptoms and physical condition.


    The System was very kind in that regard.


    Zheng Ren quickly entered the System’s operating theater and picked up the defibritor ording to the operating procedure.


    At the standard position, Zheng Ren pressed the discharge button with both his thumbs to defibrite the patient.


    As expected, the defibritor failed.


    He injected beta-blockers intravenously and changed the concentration of various drugs but there was still no effect.


    The simtion mannequin’s heart rate was still showing ventricr fibrition and after a few minutes, the electrocardiogram gradually became straight.


    The simtion mannequin died.


    Zheng Ren stood in the operating theater with a frown and began to think.


    Countless journals and documents appeared in his mind, with all kinds ofplicated cases providing Zheng Ren with what direction he should go for.


    The simtion mannequin’s heartpression outside the chest was definitely ineffective.


    Zheng Ren recalled that the first-aid doctors at Sea City and Yuandian County had said that there was a method of resuscitation for non-cardiogenic cardiac arrest.


    As long as one was given enough strength, the problem could be solved quickly.


    The standard time of 20 seconds before defibrition was not wasted.


    However, the condition of the simtion mannequin showed that his vitality was drying up. The biological electric current in the heart had weakened to a certain extent, which led to the urrence of ventricr fibrition.


    This...


    Perhaps there really was no hope.


    However, Zheng Ren was unwilling to let that be the case. Dr. Mehar could still perform the surgery. He could not die just like that.


    After thinking hard, an extremely bold idea suddenly appeared in Zheng Ren’s mind.


    Giving up medicine, Zheng Ren increased the DC current of the defibritor from the standard 200J to 300J. The electrodes were pressed on the body of the simtion mannequin. Both his thumbs pressed the discharge button at the same time to shock the defibritor.


    Bang!


    The simtion mannequin bounced up on the operating table and fell down again. Both sides of the electrodes were a little charred, but the heart rate only recovered for a moment before ventricr fibrition appeared again.


    It was not enough, but his findings seemed to be heading in the right direction.


    Zheng Ren frowned and increased the current of the defibritor again.


    400J!


    However, the subject’s heart stopped then...


    Zheng Ren cursed in his heart. The subject had electrocuted himself!


    It was a good thing that he was in the System’s operating theatre and operating on a dummy rather than the actual patient.


    If things went wrong, he could start all over again. That was the only thing he could be happy about.


    Zheng Ren seemed to have found a certain pattern. His mind began to calcte the rtionship between the biological current of the heart and the current intensity of the defibritor.


    A few simr articles appeared.


    After a quick calction, Zheng Ren adjusted the defibritor’s power to 330J. Then, he began to defibrite.


    There was another bang!


    The simtion mannequin jumped off the operating table. After that, his body crashed heavily back onto the operating table.


    Zheng Ren immediately turned back to look at the ECG monitor.


    A brand new ECG oscilloscope appeared on the left side of the ECG monitor, and the heart rate returned to sinus rhythm.


    Although he was in the System’s space, Zheng Ren saw the waveform of sinus rhythm. It was so beautiful.


    It was done! That was what he had to do.
