    The technical principle of iabp is reflected here. It uses purely physical effects to allow the balloon to inject helium to expand during diastole of the patient's heart, blocking 90 to 95% of the arterial lumen. This can reduce blood pressure in the main artery.  Arterial roots, increase diastolic blood pressure and coronary perfusion flow, increase myocardial blood supply and increase cardiac activity.  Before the heart contracts, the air sac is deflated, the aortic pressure decreases, the afterload of the heart decreases, the resistance to cardiac ejection decreases, and the myocardial oxygen consumption decreases.

    So many of the above effects that can be achieved together give iabp technology a unique and incomparable advantage over other treatment methods.

    Drug treatment requires a combination of several drugs, which has many side effects and may not necessarily be effective.  Surgical left ventricular assist devices have stricter anticoagulation requirements for patients than iabp, and the risks are higher.  The various advantages of iabp are destined to make iabp the first choice for patients who are eligible for iabp after the advent of iabp technology.

    Various new technologies are good, but any medical operation has its technical difficulties, and iabp is no exception.  Based on the above-mentioned principle of action of iabp, the balloon must have the best physical effect in human blood vessels. Like the balloon for hemostasis, the volume after expansion of the balloon needs to reach the target set by the doctor for the patient, otherwise the effect will be greatly reduced.  .

    Choosing the right balloon catheter model for the patient¡¯s arterial size becomes critical.  There are ones for adults only, and there are ones for children.  There is a slight deviation in the blood vessel diameter values ??between women and men. Factors such as the patient's fatness, thinness, and blood lipid level will also show different blood vessel diameters.

    To say this, the medical equipment model used by adults cannot distinguish the small thickness gap.  What's more, the four conventional models of iabp catheters have a small difference in thickness but a large difference in length, which shows that doctors have to 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 top of the human blood vessel, and the tail end is to go to the renal artery under the diaphragm.  It takes a balloon of such a large volume to affect the blood flow of the human body's aorta.

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

    After the machine is connected, the surgeon observes the patient's blood pressure, heart rate, etc. on-site after getting on the machine.  Based on these values, Dr. Chen makes fine adjustments.  After several debuggings, I always felt that something was not quite satisfactory.

    Time passed by minute by minute, and the night became so dark that I couldn't even see my fingers.

    It¡¯s ten o¡¯clock at night.

    After a day¡¯s work, the leader is no different from his subordinates, with tiredness on their faces.

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

    "No more." Zhang Huayao said. Dean Liang had eaten too much for dinner tonight, and he was a little too full after drinking coffee.

    Hearing what he said, the secretary went to get him a cup of Longjing tea and brought it to him.

    Having no time to drink tea, Zhang Huayao flipped through the medical records in front of him.

    Shen Youhuan guessed that he was captured by Dean Liang to help his compatriots conduct cross-ocean consultations and study patient medical records.

    Whose medical records are there?  If the dean can personally invite experts from the hospital to come to the office to look at the medical records, it must be the medical records of a wealthy and noble person.
