Chapter 1757： Tilt test

"The patient has no coronary heart disease!" Su Yun said habitually.

But he moved slightly, but sat down steadily. Did not follow the car, but looked at the back of Zheng Ren, thoughtful.

"Cloud brother, Zheng boss, what is this?" Yan Yingjie has been chaotic, and asked anxiously.

"Buy medicine, go to the pharmacy to buy food? You really don't say, there is a hospital to buy glutinous rice, maybe the pharmacy also sells food." Su Yun's answer is not serious.

"..." Yan Yingjie did not know how to answer it.

"Cloud brother, you said that I don't send my dad to a mental hospital. Will his illness be heavier? Do you want to live in a quadrangle? I am afraid that he can't think of it anyway, jump from the upstairs." Said with distress.

"Hey, old man, I haven’t earned less in these years, and there are quadrangles." Su Yun saw Zheng Ren walk into the pharmacy and started to fight with Ying Yingjie.

"The old house of your own home, isn't this waiting for the demolition? But I said that I want to protect the cultural relics. You said that there is good protection for an old house." Ying Yingjie said, "I have to sort out the garbage after a while, I ......"

"How come you pick up the garbage classification." Su Yundao: "Nothing, I think the boss's expression should be nothing big, you can rest assured."

"Yun Geer, Pengcheng's face, said that Zheng boss has cured a sect of a landlord. Is this really true?" Although Ying Yingjie was in a hurry, but he could not go, but he and Su The clouds are smashing.

"What kind of division is a bath in a bathhouse." Su Yun said with a smile: "If you are a feudal superstition, don't talk."

"Oh..." Yan Yingjie stunned, thinking that the cloud brother was young and daring, and the geologist became a bath in his mouth.

Soon, Zheng Ren came out of the car and returned to the car.

"Glycerin has risen in price." After Zheng Ren got on the bus, the first sentence said this was actually this.

Su Yun is different.

Doctor, who is okay to go to the pharmacy to buy medicine? Now hospitals have zero drug additions, drugs are cheaper than pharmacies, and there are no other shortcomings besides queuing and registration.

The price of nitroglycerin has risen, which has nothing to do with the boss.

“How much has it increased?”

“10 times? 20 times?” Zheng Rendao.

"..." Su Yun didn't know anything about this, and suddenly he was shocked.

"The former nitroglycerin was a big bottle. I don't know how many grains there are. Sometimes I let the patients go to the pharmacy to buy them." Zheng Rendao, "Now the big bottles are cheap, only the fine packaging is left. Packaging accounts for 95% of the retail price, you talk about..."

"Don't talk nonsense, say something right." Su Yundao, "What do you buy nitroglycerin?"

"Do a tilt test." Zheng Rendao.

“Tilt test? Is it to see if my dad’s brain is easy to use? Or is it flexible and inflexible?” Qi Yingjie asked, “Zheng Bo, the spiritual class you just said...”

"It's an autonomic nerve, not a spirit." Zheng Ren corrected. "Now consider not a mental illness, don't talk about it."

How does Zheng’s attitude of talking to him be the same as that of his son?

Yan Yingjie is a bit strange.

"The erectile response of the patient is similar to the clinically occurring syncope, so it is used to aid in the diagnosis of vasovagal syncope. Is this?" Su Yun asked.

"Ok."

"What are we doing with you?" Su Yun did not understand.

"Look at it, and in order to increase the effect of the tilt test, the effect is more obvious with nitroglycerin." Zheng Rendao, "I am worried that the father will have a temporary discomfort, and the family can't handle it."

"You have nothing." Su Yundao.

"Do you have 120 first aid?" Zheng Rendao, "Let Zhou Litao come directly to the first aid kit. If there is anything, I can handle it immediately."

"Do you think this is a private use of the public?" Su Yun sprayed.

"Patients, as long as the resources are used on the patients, it is not." Zheng Rendao, "If I drive 120 ambulances out, it is a public use."

"Don't tell me, I listened to the teacher. In the first 20 years, he went to the flying knife. The local hospital was driving 120 ambulances to go out to play." Su Yun laughed.

"Now there is no, 120 first aid can not run." Zheng Rendao.

Yan Yingjie listened to the two people chatting here, and they were a little anxious. They took the time to interrupt the conversation between the two and asked: "Zheng boss, what is the tilt test?"

"Oh..." Zheng Ren thought about it, and it was very troublesome to explain, but the family members of the patient asked, they could not say nothing.

Let's say that the nitroglycerin should be used for the tilt test. It is still slightly irritating, and the patient's family should cooperate.

"Let's talk about it, oh boss." Zheng Rendao: "When the human body is erect, 300~800ml of blood accumulates in the lower limbs due to gravity, causing central venous pressure, stroke volume and arterial blood pressure drop, and reflex causing sympathetic tone. Elevated, manifested as increased heart rate, mild systolic blood pressure, and mild diastolic blood pressure."

Su Yun met Yan Yingjie with a slap in the face and interrupted Zheng Ren’s words. “A friend of high blood pressure, do you have it?”

"Yes."

"The first thing to get up every morning is to measure your blood pressure. Lying in bed, lying down, because the blood pressure is not stable when standing. www.novelhall.com~ The boss just said, it means this."

Hey, explain it in person, and Ying Yingjie will understand it right away.

Su Yun is also more helpless, the boss should be very anxious to do the test immediately, the explanation is too professional.

"Well, basically this is the case. I think your father has autonomic function problems." Zheng Ren continued: "The blood vessels in patients with vasovagal syncope are more severe than normal in the lower limbs, the central venous pressure is significantly reduced, and the blood volume is returned. Reduced, sympathetic tone continues to increase."

Yan Yingjie did not understand half of it.

"Then it causes a significant increase in ventricular contractility, over-stimulation of the baroreceptors of the posterior inferior wall of the left ventricle, resulting in a reflexive decrease in sympathetic tone, vasodilation, decreased blood pressure, sudden ischemic brain damage, syncope, and sometimes increased vagal tone. , bradycardia."

"Boss, do you have research on the unmyelinated C nerve fiber?" Su Yun suddenly asked.

“Have you studied? Use a mouse in the lab?”

"Well, it can be interesting." Su Yun smiled proudly: "I cut off..."

Next, Yan Yingjie is like listening to the Bible, listening to Su Yun telling the story of cutting off the unmyelinated C nerve fibers of the mouse in the laboratory.

After 20 minutes, the car drove home, Zheng Ren got off the phone and called.

He first called Zhou Litao and asked if he was too busy. He then said about his situation.

Zhou Litao was so interested. He felt that Zheng’s boss was really guilty, and the patient who fainted when he met, did not forget to ask himself to run out and take a look.
