Capítulo 1567: Chapter 1667: Technical Compensation
The principle of IABP technology is reflected here, utilizing purely physical effects. During the patient’s cardiac diastole, the balloon is inflated with helium, blocking ninety to ninety-five percent of the arterial lun. This increases blood pressure at the aortic root, enhances diastolic pressure, boosts coronary perfusion flow, and improves myocardial blood supply, facilitating cardiac function. Before cardiac systole, the balloon deflates, thereby reducing aortic pressure, decreasing the heart’s afterload, reducing resistance to cardiac ejection, and ultimately lowering myocardial oxygen consumption.
These nurous effects combined make IABP technology possess incomparable unique advantages over other treatnt thods.
dical treatnt requires multiple drugs used together, with many side effects and uncertain efficacy. Surgical left ventricular assist devices demand more stringent anticoagulation requirents than IABP, posing higher risks. Due to the various advantages of IABP, since its inception, clinical doctors now prioritize the IABP approach for patients within the IABP indications.
Although various new technologies are excellent, every dical procedure has its technical difficulties, and IABP is no exception. Based on the aforentioned IABP chanism, for the balloon to exert the best physical effect within the human blood vessels, akin to balloon hemostasis, the expanded volu of the balloon must reach the target set by the doctor for the patient; otherwise, the effect will be significantly compromised.
Choosing the right balloon catheter size that matches the patient’s arterial vessel size becos crucial. Adults have models specifically for them, and children have theirs accordingly. There is a slight variation in vessel diater values between females and males, and factors such as the patient’s body weight, fat levels, and blood lipid levels will also present different vessel diaters.
That being said, dical equipnt models for adults do not differentiate extrely finely in terms of diater differences. Moreover, the routine four IABP catheter models differ more in length than in thickness, indicating that doctors must choose models based on the patient’s height. This is because, in addition to the balloon catheter’s thickness, the balloon catheter must be placed near the opening of the left subclavian artery at the top of the human blood vessel, extending to the renal artery under the diaphragm. A balloon of such significant volu is required to affect the blood flow operations of the human aorta.
It can only be said that when many subtle differences affect treatnt outcos, it relies on the doctor’s experience and operations for technical compensation.
Once the machine is connected, the surgeon observes the patient’s blood pressure, heart rate, and other conditions post-connection. Based on these values, Doctor Chen makes fine adjustnts. After several adjustnts, there still seems to be so dissatisfaction.
Ti passes second by second, and night has long since fallen to a pitch-black state.
It’s ten o’clock at night.
After a day’s work, the leader and subordinates are no different, weariness showing on their faces.
Sitting on the sofa chair in the director’s office, Zhang Huayao let out a big yawn. In front of him, on the coffee table, the director’s secretary served him a cup of coffee to relieve his fatigue.
“I won’t drink it,” Zhang Huayao said, having been overfed at tonight’s dinner by Director Liang, and coffee felt a bit too much.
Hearing this, the secretary replaced it with a cup of Longjing tea and served it.
No ti to drink tea, Zhang Huayao turned over the pages of the dical records before him.
Shim Youhuan guessed it right; he was brought in by Director Liang to help with an overseas consultation for his compatriots, studying the patient’s dical records.
Whose dical records? To warrant the director personally inviting experts from the hospital to co to the office to view the dical records, it must be those of a person of great wealth and importance.
