The technical principles of IABP are reflected here, using pure physical effects, allowing the balloon to input helium to dilate during the patient's diastolic period, blocking 90 to 95% of the arterial lumen, so that blood pressure can be placed in the main body.

The root of the artery increases diastolic pressure and coronary perfusion flow, increase myocardial blood supply and increase the increase in cardiac activity. Before the heart contracts, airbag exhausts, aortic pressure drops, heart afterload decreases, heart ejaculation resistance decreases, myocardial consumption

The oxygen level decreases.

The above many effects can be achieved together give IABP technology an incomparable unique advantage over other treatment methods.

For drug treatment, several drugs are required to use in combination, with many side effects and not necessarily good results. The surgical left ventricular assisted device has stricter anticoagulation requirements for patients than IABP and has higher risks. The various advantages of IABP are destined to be after the IABP technology is released.

, clinicians are now the preferred IABP regimen for patients with IABP indications.

All kinds of new technologies are good, but any medical operation has its technical difficulties, and IABP is no exception. Based on the above principle of IABP, the balloon should play the best physical effect in the human blood vessels, just like the balloon stops hemostatic.

, the volume of the balloon after expansion needs to meet the goals set by the doctor for the patient, otherwise the effect will be greatly reduced.

Choosing a balloon catheter model with the right arterial vascular size becomes crucial. Adults have adults and children have children. There are slight deviations in the vascular diameter values ​​between women and men, and the patient's body is fat and thin and blood lipids

Factors such as this will also show different diameters and sizes of blood vessels.

After all, the models of medical devices used by adults cannot be divided into very subtle differences in thickness. What's more, the differences in thickness of the four conventional IABP catheters are small, but the differences in length are large, which shows that the doctor should choose the model based on the patient's height.

.This is because, in addition to the thickness of the balloon catheter, the balloon catheter is placed near the opening of the left subclavian artery at the apex of the human blood vessels, and the caudal end is to reach the renal artery under the diaphragm. Only such a large volume of balloon can affect it.

Blood flow to the human artery.

It can only be said that when many subtle differences affect the treatment effect, they can only be made up for by the doctor's experience and operation.

After the machine is connected, the surgeon observes the patient's blood pressure and heart rate on the spot after the machine is on the machine. Based on these values, Dr. Chen fine-tunes. After several debugging, he always feels not satisfied.

Time passed minute by minute, and the night was so dark that it was so dark that it was impossible to see your fingers.

It's ten o'clock in the night.

After a day of work, the leader is no different from the people below, and he is tired.

Sitting on the sofa chair in the dean's office, Zhang Huayao yawned a big yawn. On the coffee table in front of him, the dean's secretary brought him a cup of coffee to relieve his illness.

"I won't drink anymore." Zhang Huayao said, "Director Liang was fed too much for dinner tonight, so I was a little overfilled when I drank coffee.

After hearing what he said, the little secretary went to exchange him a cup of Longjing tea and served it.

I didn't have time to drink tea, so Zhang Huayao's hand turned over the medical record paper in front of the page one by one.

Shin Youhuan guessed that he was caught by Dean Liang to help his compatriots conduct cross-border consultations and study patient medical records.
