In the clean room, the cries of three cardiopulmonary monitors sounded a little messy. Sun Lien and Director Huang were in the room and felt a little uncomfortable for a moment - it was too quiet here.

In the room, several hospital infection staff wearing P4 protective clothing were continuing to install the breathing line, while other medical staff were waiting outside the clean room, preparing to wait until Sun Lien or Director Huang was unwell and could not continue to persist.

Yuan Ping'an and Dr. Cao Yanhua each brought two nurses to wait, while Dr. Bruen and Dr. Pascal also decided to prepare for waiting together.

"You wait for two hours inside and then come out to change shifts." Yuan Ping'an said politely to his team leader, "Wear a mask for an hour. If the patient needs chest compressions, then you should retreat quickly and let's go in and do the press-Nicole must not take off the mask inside, this is the plague!"

"I know, I know." Sun Lien agreed guiltily. Yuan Ping'an met him at the Fourth Court for the first time when he met President Song in the Fourth Court. He was probably told that he had heard a lot of his "heroic feats" in the past month, so he was so nervous.

"The last time I took off my mask in the clean room to rescue the patient?" Director Huang was really shocked. Unexpectedly, Dr. Xiao Sun was still a cruel person.

Sun Lien coughed awkwardly, and just as he was about to say something, he suddenly heard a sharp alarm sound.

The monitor beside Tang Xingde cried out, Sun Lien was already familiar with the movement - the ventricular fibrillation waveform!

"Push the defibrillator and prepare two lidocaine intravenous injections, hurry up!" Sun Lien hurriedly rushed to Tang Xingde and started chest compressions. With an n95 mask, chest compressions were very laborious, but he had only put them on for a short time, and his physical strength was still enough to hold on.

Sun Lien suddenly glanced at the status bar on Tang Xingde's head. Sure enough, a new status was added - ventricular fibrillation (8/8 times before the successful defibrillation was released).

Eight defibrillations were used to calm down, but this at least means that the person could be saved. Sun Lien felt a little relaxed. While doing chest compressions with all his might, he quickly wondered why Tang Xingde suddenly had ventricular fibrillation.

In addition to defibrillation, correcting the causes of ventricular fibrillation is also one of the important means to relieve ventricular fibrillation.

There are five known status columns: "The level of white blood cell is greatly increased", "high fever", "severe pneumonia", "sinus rhythm ejaculation" and "reduced fibrinogen concentration". The significantly increased white blood cell level means that the patient is in a serious bacterial infection. Bacterial infection may lead to bacterial emboli in the blood and block the coronary artery, thereby producing ventricular fibrillation.

High fever? This is one of the evidence that the body is resisting bacteria. In order to control the collateral physical damage caused by high fever, doctors from the Fourth Hospital have used ice blankets for three people to cool down. None of them inhaled depolarized muscle relaxants. This high fever is naturally not caused by malignant high fever. Then, conversely, excessive core temperature may indeed lead to large-scale death of cells, thereby releasing too much potassium. After these potassium enters the blood, it will cause excessive blood potassium, which will quickly cause ventricular fibrillation to cause death.

Needless to say, severe pneumonia can be combined with sinus rhythm. Pneumonia can lead to insufficient oxygen content in the human body. The heart rate of these three people is so scary. The heart does not get enough oxygen under high intensity load, which results in continuous lactic acid accumulation, which leads to ventricular fibrillation.

If the fibrinogen concentration decreases, the possibility of dIc is directly spent. If the patient breaks into dIc, then the coronary artery may be blocked by thrombosis and cause ventricular fibrillation.

There are five states and four completely different causes of ventricular fibrillation. Each item has a high possibility, and the treatment method for each item is different. Sun Lien must immediately find out the real cause of the patient's ventricular fibrillation and treat it. Otherwise, even if Tang Xingde restores sinus rhythm after eight defibrillations, he might have to tremble again in a few minutes.

The first ventricular fibrillation requires eight electric defibrillation times. According to general experience, the number of defibrillation will increase and the difficulty of defibrillation will become greater and greater. Sun Lien even felt that if Tang Xingde trembles again after this defibrillation is successful, he may not be able to save him.

Think about it quickly, think about it quickly! Sun Lien pressed Tang Xingde's chest hard, and shouted to Yuan Ping'an who was rushing into the clean room, "Come here to help!"

The moment the monitor called the police, Yuan Ping'an rushed in with nurses Xiao Guo and Zhong Yu. Yuan Ping'an was waiting to take over the chest compression at any time. Xiao Guo rushed to the rescue vehicle five meters away with three steps, pulled the defibrillator and rushed back to start charging. Zhong Yu pulled out the drawer under the rescue vehicle, took out lidocaine from it and started intravenous injection.

Sun Lien dodged the space, but Yuan Ping'an took over the chest compressions, and he almost took two steps back. After confirming that there was no other status bar on Tang Xingde's head, he began to think about countermeasures soon.

The possibility of Yersinia plague is extremely low to cause bacterial embolism. When bacteria invade tissues in the human body, the part of the necrotic tissue and bacteria mixed with the bacteria falls off and floats in the blood to form bacterial embolism. However, the Tang Xingde family's time to infect the plague is too short, so it should not be enough to produce bacterial embolism.

Hyperkalemia? This is possible, but the three patients are in extremely high temperature state for a short time. Although there are indicators of acute renal injury, the human organs have the ability to compensate. Based on Tang Xingde's current renal function indicators and body edema, his kidneys are far from exhausted. The possibility of hyperkalemia is not too high.

dIc? This is easy to eliminate. Sun Lien glanced at the intravenous infusion needle on Tang Xingde's arm, and there was no trace of blood leakage. This can also be eliminated.

"The possibility of acidosis is the most likely. Nurse Zhong, ten milliliters of 5% sodium bicarbonate, intravenous injection!" Sun Lien locked in the most suspicious cause, not that hyperkalemia is completely impossible. In comparison, 5% sodium bicarbonate infusion is the fastest, and even if the judgment is wrong, it will not cause direct danger to the patient - not to mention that sodium bicarbonate itself also has a therapeutic effect on patients with hyperkalemia.

"The fourth defibrillation, 22oJ, dodge!" Xiao Guo completed the third defibrillation, but the effect was still not ideal. Yuan Ping'an was still doing chest compressions, but there was already a layer of fine sweat on his head, and it seemed that he would not last long.

"I'll take over, you're going to let Dr. Cao in." Sun Lien stood beside Yuan Ping'an, "Change hands with me after the fifth defibrillation!"

High-quality chest compressions are an important factor in improving the success rate of defibrillation. The so-called high-quality means that the doctor's chest compressions must have sufficient strength and frequency. This is amazing for physical strength, so it is very necessary to replace people in time in the middle of chest compressions.

"I'll do it." Bruen walked in with a mask and protective supplies. His big bearded man looked a little ridiculous under the n95 mask. "You young doctors are not strong enough, and don't eat meat on their own?"

For the first time in Yuan Ping'an's life, he felt that the American Red Neck Motorcycle Knight was so cool.
