Chapter 1570 【1570】The Big Problem

Since many domestic advanced medical instruments are imported, the keys on the machines are all in English, and doctors can recognize them by virtue of their familiarity with the English letter "AUTO" beginning with "automation".

Treating patients with a machine is much more difficult than washing clothes with a washing machine at home. Sometimes we cannot use a fully automatic washing machine, and we need to adjust the parameters to wash some special clothes. Like a medical machine, at this time the doctor will turn on the "OPENATOR" working mode and operate the machine by himself. Just like the machine automatically adjusts the parameters, the doctor needs to use the human brain to distinguish the waveform value to select the trigger mode to adjust the inflation and deflation time of the balloon and other operations.

The same doctor observes from top to bottom, first look at the electrocardiogram. Some patients themselves have arrhythmia, such as sinus tachycardia and atrial fibrillation, etc. These conditions will affect the effect of counterpulsation. The most direct impact is the improper proportion of counterpulsation. This kind of situation is not afraid, as long as the proper counterpulsation ratio and balloon inflation and deflation time can be corrected.

Look at the arterial pressure of the red wave, which is usually the most important graphic that surgeons need to observe.

Like the electrocardiogram, the pressure graph loaded with balloon pressure has a group of complete periodic changes. If the group of periodically changing graphs, like the electrocardiogram, appear to be superimposed in advance or slow down to separate, Basically, it can be concluded that it is too early or too late to charge and deflate. At this time, the doctor only needs to adjust the inflation and deflation time of the balloon on the machine.

These are the problems that are relatively easy to judge and solve. The experienced doctor Chen ruled out one by one, so he told the superior doctor that he had adjusted the machine parameters.

The difficulty is where, after adjusting the machine parameters, it is found that the problem has not been solved. The pressure value after balloon inflation is not in place. If it is a factor other than machine parameters, other reasons that affect the counterpulsation effect cannot be solved by light-tuning machines.

The doctor needs to recheck the balloon catheter that the machine connects to the human body to work.

Adjusting the catheter is not like adjusting the parameters by simply pressing a few buttons on the machine, it is all a risky operation. Who would have thought that if the tubes already placed in the patient's body were moved around, what would happen if there was a sudden hemorrhage? When the whole body of the patient is heparinized, it is really possible to cause bleeding if the tube is fiddled with randomly.

It is the surgeon who would feel dizzy thinking of this, how I hope it is not.

Shen Youhuan also hoped that it was not the case. If a problem arises, he can only face the reality and say to Dr. Chen: "Try to make the tip of the balloon go back a little bit or push it forward a little bit."

The position of the balloon is not in place, which leads to the failure of the preset pressure, which is usually one of the factors affecting the effect of counterpulsation. Looking at the arterial pressure waveform now, it seems that this factor has disappeared.

"I tried it and it didn't work." Dr. Chen replied, praying in his heart.

"If it doesn't work anymore, maybe you need to change to a larger or smaller catheter." Shen Youhuan said to encourage the people below, and suddenly thought of something, turned his head to the little junior sister Xie Wanying and asked, "Do you have any ideas? "

Asked by senior brother Shen, Xie Wanying, who was also observing the operation, expressed her opinion: "As senior brother Shen said, the top of the balloon can be extended forward."

"I said I will try." Dr. Chen emphasized repeatedly.

"Don't be too anxious." Xie Wanying said.

Dr. Chen was stunned: a medical student told him not to be too anxious, did he hear wrong?
