Zhou Yewu showed a melancholy expression.

There must be nothing good about Li Qifeng’s appearance with such an evil smile!

He murmured in his heart: "How many questions are there? Director Chen Riyuan didn't even have to ask a question even if he kept asking."

Li Qifeng continued to ask: "The last question is the cause of heart failure, please tell me in detail!"

The key to this question is that it is not the cause, but the two words in detail. These two words need to be circled and tested!

Zhou Yewu looked embarrassed.

The causes of heart failure are nothing more than infection and increased heart load caused by various reasons, but how should we talk about this specifically?

Zhou Yewu recalled the content of acute heart failure like a book in his mind.

At this time, Li Qifeng seemed to feel that the question was somewhat undirected, so he changed his words and said, "Guess the cause of heart failure in this patient."

But what is the difference between this question and the previous question?

Instead, it also increases the difficulty of one's own judgment.

Zhou Yewu cursed softly in his heart: "mlgb, I always make things difficult for me. I am just a small training teacher. Why don't I feel like I'm taking me to study and interrogating me?"

He looked at the heart-dead elderly person and took a deep breath.

For example, the causes of heart failure include diffuse myocardial damage, such as acute coronary syndrome, acute severe myocarditis, perinatal cardiomyopathy, etc., which can indeed lead to pump failure caused by acute left ventricular myocardial damage, reduced myocardial contraction force, reduced cardiac displacement, and acute pulmonary edema! However, this still requires test results related cardiac indicators such as troponin as clinical basis, and Zhou Yewu cannot see it for the time being!

If you consider heart failure caused by cardiogenic shock, this will lead to insufficient irrigation of tissues, which is manifested as hypotension. This is a bit like the scene when Zhou Yewu saw this old man at home!

There is also acute heart afterload excessively, such as sudden increase in arterial pressure or hypertension crisis, sudden excessive physical labor in patients with original valve stenosis or left ventricular outflow obstruction, acute arrhythmia and acute heart failure. These will cause sudden increase in ventricular diastolic pressure due to excessive heart afterload, causing acute pulmonary edema!

Zhou Yewu looked at the old lady and shook her head. The old lady didn't seem to know the old lady's past history very well, and even the history of hypertension was not very clear! It was a bit difficult to know the past history from her mouth.

Then there is an acute preload that is too heavy, that is, excessive capacity load, such as regurgitation of the heart valve and the non-closure of the left and right catheters, which cannot be seen with the naked eye! You still have to wait for the auxiliary results to make the diagnosis clear.

"I guess this is a nonsense cause. I don't have any basis. Isn't it just a random guess?" Zhou Yewu couldn't help but complain.

Finally, there are heart failure caused by some non-cardiogenic factors, such as hyperthyroidism crisis, anemia, infection with septic infection, rapid and large amount of fluid replenishment, etc., which leads to a sharp increase in capacity...

Anyway, there are a lot of causes of acute heart failure, but Zhou Yewu looked at the old man in the resuscitation room and shook his head helplessly!

He concluded: "At present, it is highly likely that heart failure caused by cardiogenic shock is suspected! But it is necessary to further improve relevant examinations and clarify the diagnosis!"

Li Qifeng suddenly laughed as he listened to Zhou Yewu's simple words: "Your answer is really clinical."

It is certainly nothing wrong to say it wrong.

However, this question is indeed a bit difficult.

Li Qifeng pointed to the old man and said, "Look at the blood pressure value on the electrocardiogram monitoring."

Zhou Yewu looked at the blood pressure of the ECG monitoring and read it: "132/80mmhg."

This blood pressure is quite normal...

"If the blood ejaculation function decreases, Zaoli says that it cannot maintain normal blood pressure, so it should drop slightly." Zhou Yewu became a little confused.

Li Qifeng smiled and said, "When I was rescued, I pushed adrenaline. Even if my blood pressure dropped, I couldn't tell it. Moreover, some of my basic blood pressure was high, so it was not easy to judge."

Zhou Yewu nodded: "So, Brother Feng, what do you think is appropriate to consider?"

Li Qifeng: "Let's wait for further auxiliary results to come out."

Zhou Yewu suddenly didn't know what to say.

The instructor secretary of this emergency department likes to fool the small rules and regulations.

What a dream, the explanation is so vague...

It can be said to be extremely round! There is no flaw at all! Zhou Yewu even racked his brains to answer his question, but he was unable to refute it when facing his few words of answers!

...

At this moment, an emergency nurse shouted: "The takeaway is here, Dr. Li."

When Zhou Yewu heard the takeaway arrived, he heard that Zhou Yewu's stomach rang again.

He looked at Li Qifeng and whispered: "Brother Feng, are you going to have a meal?"

Li Qifeng pointed to the nurse's direction and said, "You follow the nurse to the doctor's classroom first, fill in your stomach first. I see that you are so hungry that your face is white and your blood sugar is like low blood sugar. Don't let me wait and save you."

It would be a big mistake if you don’t have hunger!

I could have eaten sweet duck leg fried rice at home!

It’s not because of your emergency department that you are hungry like this dog!

Zhou Yewu muttered in his heart and walked towards the doctor's classroom.

Li Qifeng was still staying behind to do the follow-up medical advice for the elderly with heart failure! Doctors on the front-line emergency department often cannot be determined by themselves. If the patient is not stable, he will not be at ease even if he eats.

Zhou Yewu walked into the doctor's classroom. At this time, a bunch of nurses had gathered in it. It seemed that they were all emergency nurses who were in the emergency room.

As soon as he stepped forward, Zhou Yewu suddenly felt a little regretful again.

Without Li Qifeng bringing it in, it seems a bit embarrassing to come in to eat like this.

All the nurses stared at Li Qifeng...

It seems that no one knows him!

Yes, no one knows Zhou Yewu.

What a fucking thing, should I explain with a tough face?

At this time of dilemma, another nurse came from behind Zhou Yewu.

The nurse looked at Zhou Yewu and smiled and said, "Hello, is your little brother coming to our emergency room for dinner?"

Zhou Yewu looked at the nurse's pretty face, but she didn't think about who she was?

When did this cause peach blossoms?

At this time, the young nurse took the mask from her pocket, put it on again, and said, "I think about who I am now, Dr. Zhou from the respiratory department."

I heard the nurse call me Dr. Zhou.

Then when he saw the nurse's big watery eyes, Zhou Yewu immediately screamed: "Oh! It's you!"

The nurse also exclaimed in an imitation: "Well! It's me!"

It made everyone laugh.

Just when she was embarrassed, she pushed Zhou Yewu directly in, "Let's have dinner, I see you were just chatting with Dr. Li, he asked you to have dinner here."

Zhou Yewu looked at the boiled fish, crayfish and barbecue on the table...
