When he arrived at the hotel, Wu Mian sat in the main seat and was talking with the director of Pengcheng People's Hospital.

It was possible to feel that Wu Mian was very happy, and even some emotions called pleasure spread across him.

"Teacher Wu." The group came in and greeted Wu Mian first.

"Sit down." Wu Mian said with a smile, "The surgery is done very well."

In a word, Ren Haitao finally felt relieved. After all, it was the first time to perform a new technique of mitral valve clamping on the human body. Teacher Wu was not here, so he was inevitably worried.

"Teacher Wu, you will learn how to run smoothly." Gao Baixiang asked.

"It's okay." Wu Mian nodded, "It's initially decided to cooperate with Lanke and Huaxia Minimally Invasive. Director Gao, you may be busy recently."

"Oh? Do patients with mitral valve regurgitation need to concentrate on their surgery?"

"No." Wu Mian said, "Lanke is preparing charitable assistance to 5,000 sets of interventional surgical consumables for infants and young children with congenital heart disease."

5000 sets...

Although I don’t know the cost, it is at least several hundred million yuan in terms of sales price.

Gao Baixiang looked at Wu Mian in surprise, he didn't know that there was such a thing.

"Director Zhao, I'll ask you in the future." Wu Mian said with a smile, "There are suitable patients who can't afford the surgery or can barely do it, but if they are going to get hurt at home, go to my side."

"No problem, Teacher Wu, you are a kind act. You will have to pay a cup to you later." Dean Zhao said.

"It should be done." Wu Mian shook his head and said, "Nothing else, Dean Zhao will help identify patients more. After all, there are so many free consumables, and those with money will be treated normally, leaving opportunities for children who have no money."

Wu Mian spoke very seriously. Dean Zhao knew the priorities and nodded, "Teacher Wu, don't worry, although it is troublesome to identify the patient's family conditions, I will do my best to do it."

There are too many things involved in this, and Wu Mian doesn't want to set the conditions too harshly. When the water is clear, there will be no fish, and when the people are careful, there will be no disciples. Wu Mian understands the most basic truth.

"Let's just implement it quickly. Your economy is well developed, and there may not be many people in need. Anyway, you can help contact us first." Wu Mian said politely.

"Look at what you said, isn't this what we should do?" said Dean Zhao.

While speaking, the waiter handed over the dishes, and Ren Haitao finally found an opportunity.

"Teacher Wu, the blood gas analysis of the oxygen partial pressure of the patient just now was really low." Ren Haitao said the result directly.

"Oh, have you regained your lungs for ventilation? What medicine have you given?" Wu Mian asked.

"Yes." Ren Haitao nodded and briefly mentioned the rescue medication he used at that time. "The patient was in good condition after rescue, and I saw that the operation was over."

"I don't worry if you are here." Wu Mian looked at Ren Haitao and said with a smile.

"Teacher Wu, I just felt something was wrong at that time, but I couldn't tell what was wrong." Ren Haitao said, "I have no choice but to call you."

"Oh, I haven't encountered it before?" Wu Mian asked.

Ren Haitao shook his head, and the two directors of the People's Hospital looked at Wu Mian without blinking, listening to Teacher Wu's explanation.

If Ren Haitao is not as alert as intuition, and even calls Teacher Wu, it is very likely to cause serious consequences. As for why this situation occurs, they think it is a supernatural event.

Similar things are definitely not the norm. If so, the monitoring content of blood oxygen saturation is meaningless.

"The serious imbalance in the blood flow ratio of ventilation during single lung ventilation is the most likely cause of this condition. When single lung ventilation is ventilated, the blood flowing through the lungs without oxygenation returns to the left atrium, causing venous blood doping and causing PaO2 to drop."

Wu Mian began to tell the story, although he didn't see the patient with his own eyes, he could guess just by guessing.

"Under normal circumstances, the blood flow in the right lung is about 10% more than the left lung, so the incidence of hypoxemia increases compared to the collapse of the left lung. This patient has blood flow due to the lying position on the left side and the right lung is not ventilated, resulting in pseudo-shunts of arteriovenous blood flow, and the ratio of ventilated blood flow in the right lung decreases, which ultimately leads to a decrease in PaO2."

"This is the most basic principle of single-pulmonary ventilation. Although there is very little chance of problems, so that no one can remember this, Lao Ren still has the most basic alert."

Wu Mian looked at Ren Haitao with praise.

So that's how it is. Ren Haitao recalled some memory fragments at this time. When he saw the patient lying on his left side, he felt a little uneasy, and there was a reason for this.

"There is a lot of sputum in the left bronchus before the operation, which is easy to block the bronchus. Moreover, when the abdominal cavity is lying on the side, the contents of the abdominal cavity push upwards, and the residual function of the function decreases, causing atelectasis on the left lung, resulting in a decrease in ventilation function of the left lung, further aggravating the imbalance of the blood flow ratio of ventilation."

Wu Mian's words are easy to understand. Everyone here is the chief-level anesthesiologists, and they immediately understand what Teacher Wu is saying. However... Teacher Wu's explanation still cannot perfectly explain the patient's condition.

Seeing that several people looked puzzled but did not dare to ask, Wu Mian smiled slightly and said, "Many years ago, about 30 years ago, domestic anesthesiologists began to perform single-pulmonary ventilation. Several directors should have often heard a saying--Your double-lumen tube is not in a good position."

Indeed, this sentence almost touches the hearts of the directors here.

Poor position of the double lumen canal lead to a decrease in blood oxygen is the most important problem facing the cannulation, and it is also one of the landmark operations to evaluate the level of intubation of an anesthesiologist.

"Although hypoxic pulmonary vasoconstriction or thoracic opening affects pulmonary blood flow, it is an important and theoretical influencing factor, if pulse oxygen drops and airway pressure changes, then the monistic diagnostic thinking tells you to first consider the location of the double lumen."

"Teacher Wu, but the patient's condition is that the blood oxygen display is different from the actual display." Ren Haitao had already figured out what Wu Mian was saying. His mind was full of the previous situation, and he didn't consider anything else, so he asked directly.

"Are you a little bit of explanation?" Wu Mian was not angry, but said with a smile.

"Yeah, yeah, what do you think, Teacher Wu?" Ren Haitao continued to ask before he realized that his words were too straightforward.

Several other people also looked at Wu Mian curiously, wanting to hear his explanation.

It will definitely not be a supernatural event, but a rare situation.

"Who have you studied the working principle of the blood oxygen saturation clip?" Wu Mian asked.

Several directors shook their heads one after another.
