The reason why the old experts came over so enthusiastically to greet Comrade Li was not just because they didn't toss the students and the regular training doctors for a day, so they were uncomfortable. After asking about Comrade Li's medical history, many experts noticed one thing at the same time - although his pain was consistent with the symptoms of lumbar disc herniation, it was relatively rare to have a sudden attack while swimming. The reason why doctors recommend swimming for patients with lumbar intervertebral discs is not only because this exercise is harmless to the disease, but also because soaking in water can greatly relieve the stress on the lumbar spine, and swimming can actually play a role in relieving pain. Swimming not only did not relieve the symptoms, but hurt Comrade Li to choke on water, which is a point that can easily attract the attention of old experts.

After discussing with Sun Lien, Hu Jia trotted all the way to the duty office by the pool and borrowed a stethoscope and a blood pressure monitor. These basic diagnostic tools can do much more than the average person thinks. The experts were amazed by Hu Jia's ability to use the diagnostic tools and how well they operated them. And Sun Lien's attention began to extend to Li Fengmin's limbs and cheeks.

The limbs at the end of the body's circulation are the places where blood circulation disorders are more likely to manifest. These areas often exhibit very characteristic diagnostic hallmarks. For example, palmar erythema, spider angiomas, polycythemia vera, Raynaud's syndrome, clubbing, etc., are excellent features to help suggest a diagnosis. These traits are very suggestive, but sometimes it takes some patience and keen attention to spot.

As for the cheeks, Sun Lien is looking for evidence of the existence of autoimmune diseases. Although SLE (systemic lupus red packets) is more common in women of childbearing age, the possibility of developing it in older men remains. If the other party has a disease such as vasculitis due to an autoimmune disease such as SLE, it can also match the symptoms he is showing now.

"Heart rate 95, systolic blood pressure 115 mm Hg, diastolic blood pressure 80 mm Hg. Hu Jia completed the examination with his hands and feet, and then began to listen to Li Fengmin's heart and lungs. The water in the pool is undoubtedly freshwater, because the osmotic pressure of freshwater is lower than that of blood, and choking on a certain amount of fresh water can cause the blood to be diluted in the alveoli. Hemodilution causes an increase in blood volume, which leads to an increase in blood pressure. At the same time, a large amount of water rushes into the blood, which can also lead to severe hemolysis. Potassium in the blood rises, and nitrogen and sodium concentrations decrease rapidly. Eventually, cardiac arrest can lead to death.

The diaphragm in older people may not be as strong as in younger people, and it is possible that choking on water may not be able to expel all the water that invades the trachea. Although the blood pressure was not high just now, Hu Jia still didn't dare to be careless. After listening carefully for a long time, it was confirmed that the old man's lungs had no rales and his heart was beating steadily and strongly, and then the examination was stopped.

The experts who came to the "consultation" exchanged opinions and basically agreed that there was nothing wrong with the old man. It may be that the lumbar disc herniation is a little serious. And just as everyone was about to disperse, an old man recognized Sun Lien.

"Hey, isn't this Dr. Sun who scolded people on stage at noon!" A white and chubby old man waved his hand at Sun Lien with a smile, and said in a cordial tone, "Lao Li is fine, you can go and play." Don't worry, I'll just ask the waiter to send him back later. ”

Sun Lien remained silent a little rudely, he was still staring at Li Fengmin, his eyes looking everywhere on him. He didn't notice that an old man next to him was talking to him at all-Li Fengmin's body did not show any obvious physical signs, Sun Lien stared at the side for at least five minutes, and he looked at the mole on the back of the old man's waist several times. But melanoma doesn't cause this symptom, and paraneoplastic syndrome doesn't produce a "slow drop" in blood pressure.

No, no, Sun Lien felt that his head was about to boil, but he just didn't understand what was wrong with Li Fengmin in front of him. He checked the status bar above Li Fengmin's head over and over again, but he just couldn't figure out why he had this prompt.

Sun Lien suddenly felt that his arm was gently tugged, he looked back suddenly, and found that it was Hu Jiazheng looking at him worriedly. And there are a lot of curious experts who only wear a pair of swimming trunks.

"What do you think, young man?" asked the chubby old man who had spoken at the beginning, smiling. It is not necessarily a bad thing for a young doctor to be so distracted in front of his patients. Sometimes when you suddenly understand a joint, you may become a key node in the transformation of an ordinary doctor to an excellent doctor. Anyway, many experts present felt that Comrade Lao Li would not have any problems, and it would not hurt for Dr. Xiao Sun to be distracted. When the old man saw that Sun Lien was called back to his senses by Hu Jia, he felt a little regretful. He tried to worry that Sun Lien hadn't figured it out yet, and tried to make up for it, "If you have anything that you don't think is appropriate, it's better to go directly to Lao Li for a physical examination." After all, it's better to watch a thousand times than to do it once!"

Contemplating a problem for a long period of time can lead to results like "gestalt collapse" or "semantic saturation" when people are relaxed. It's like seeing a Chinese character repeat a lot in a short period of time, or simply staring at a character for a long time, you will find that the character starts to become unfamiliar, and you may even forget how the character is pronounced and what it represents.

Sun Lien's concentration was a little higher than this, and when he came back to his senses, he couldn't even remember what he was thinking about. After hearing the proposal of the older person next to him, Sun Lien subconsciously walked to Li Fengmin's side and began to examine in accordance with the logic of "training doctors and following the instructions of senior doctors".

Although they are usually in school or hospitals, this group of old experts may not all be so kind. But away from home, it's a professional situation that comes after a slightly boring meeting. They were all quite interested in watching Sun Lien's examination on the sidelines, while whispering about the young doctor's examination techniques.

It's not bad, but it's not too good, that's what the experts came to after the exchange. In the eyes of these old experts, although Sun Lien's inspection action is standard, it is only a standard action in the regulations after all. He doesn't seem to have learned the technique of purposeful and skillful laziness to speed up inspections – Sun Lien is suspected of being "dogmatic."

Sun Lien is not the kind of person who has a one-eyed character, which can be seen from his previous rash proposal to use APIs to treat firefighters with organophosphate poisoning - this guy really doesn't play according to the routine sometimes. But he did a very serious examination this time, and after Sun Lien came back to his senses, he fell back into the previous confusion, and he tried to find the main reason for Li Fengmin's blood pressure drop with closer contact and examination.

"How are you feeling right now, is there anything wrong?" Diagnosing the problem is at least a little better than a blind examination trying to find out what the problem is. Sun Lien asked casually while checking the muscle strength level of Li Fengmin's lower limbs.

"I'm fine. Li Fengmin replied with a smile, he did feel that the radiating pain from his lower limbs had been reduced a lot. "But I may have drunk two more sips of water just now, and now I feel a little full. ”

Sun Lien didn't take a stubble, asked Hu Jia to pass the blood pressure monitor, and checked Li Fengmin's heart rate and blood pressure again.

"Heart rate 95, systolic blood pressure 105 mm Hg, diastolic blood pressure 75 mm Hg. Sun Lien reported the reading, and sure enough, Li Fengmin's blood pressure was dropping.

"You just said that you feel a little full?" Sun Lien suddenly thought of something, "Is it the feeling of fullness, or does you feel that your stomach is a little swollen?"

Li Fengmin asked with some confusion, "Is this any different?"
