   Zhang Huayao narrowed his eyes, not in a hurry. It\'s no use looking for an expert. This kind of patient is not a rare disease, but a relatively common fatal disease in clinical practice. If you are looking for an expert, the expert sees that this disease has habitual thinking. It is better to find a young person and ask if there is any whimsical new idea.

  It\'s too late to go home and rest. Dean Liang was going to get off work, so he picked up his jacket and said to him, "Director Zhang, let\'s go together."

   Zhang Huayao said, "I\'m going back to the emergency department."

   The people below work so actively? Dean Liang was surprised because he knew that Zhang Huayao was not such a person. Although Zhang Huayao was ridiculed by his mother, Teacher Lu, as a person who devoted himself to his career, he was not the kind of person who spent years in the hospital. People are geniuses, and the habit of geniuses is to paddle when they should, be lazy when they should be lazy, and let people do what they should do.

   To put it bluntly, Mr. Zhang has been a suave grandfather since he was a child. He wrote ten minutes of homework for one hour while others were working hard, and he ran out for a walk while others were studying hard, but the final result in the test was far less than that of others.

   Dean Liang, who wanted to understand this, was moved, and followed Zhang Huayao all the way to the emergency room to see what was the reason for this genius to go back and take a look.

   No need to go back to the emergency department to receive a text message from Eyeliner telling Xie to go to the interventional operating room, Zhang Huayao turned around and went to the interventional operating room on the spot.

The atmosphere in the    intervention room was slightly frozen.

   For patients with counterpulsation machines, some values ​​have never reached the doctor\'s expected target. Dr. Chen, who had debugged several times, was a little overwhelmed.

   Dr. Yang and Dr. Li Xiaofeng did not dare to come out. They only saw that the teacher was anxious. It seemed that the operation was not very good.

   Helpless, Dr. Chen had to ask the superior doctor for help: "Mr. Shen, you are watching, did you find any problems that we didn\'t notice?"

   Shin Woo-hwan, who was holding the walkie-talkie, said, "Have you debugged the machine yet?"

   "Adjusted." Dr. Chen was sure of this.

   First, let’s talk about what the doctor can see and perform on the counterpulsation machine. The sensor of the catheter and the electrodes attached to the patient\'s body surface are connected to the counterpulsation host to output signals. The monitor screen of the host displays waveforms of relevant data, and there are three in total.

   The top graph is green and is an electrocardiogram. Different from the ECG on the ordinary ECG monitor, after the patient is put on the balloon pressure, the heart activity will inevitably entrain the effect of the balloon. The electrocardiogram here is shown as segments of white, and these white beginnings represent the inflation and deflation time of the balloon.

   And so on, the second waveform is the red wave, which is the patient\'s arterial pressure, and the white part in the middle is also the inflation and deflation time period of the prominent balloon.

  The third graph is the pressure graph of the balloon directly, which is a blue waveform graph.

  The waveform diagram and the additional value displayed can let the doctor intuitively understand the effect of the balloon inflation and deflation on the patient\'s heart, which plays a monitoring role. Secondly, the machine is operated by people, and there are bound to be many operation buttons.

  Like many machines, more and more modern machines must have their own fool mode first, like the washing machine at home. The medical machine also has an automatic mode. The machine senses the patient\'s arterial blood pressure and adjusts the balloon pressure and inflation and deflation time by itself.
