Chapter 3534 [3534] I have never heard of it

  Mean arterial pressure is affected by factors such as drugs. If the mean arterial pressure is raised by drugs, it means that false positives are meaningless. This corresponds to what Xie said before we should take drug tests carefully before weaning off the machine.

   How to do the specific operation, in fact, has already started to do it.

  Did you do it?

  Director Wang and the others at the scene were startled. It seemed that there was no special medicine given to the patient by Mr. Xie.

   I want to talk about one more question. Significance of mean arterial pressure monitoring Human perfusion is closely related to cardiac output of the heart. Cardiac output can be measured with picco technology, but transesophageal echocardiography can be used without picco technology.

   Xie Wanying said: "We just measured the heart condition supported by the full flow of the membrane lung, mainly measuring the left ventricular ejection fraction and the function and volume of the right ventricle."

  Since the doctors are now gathering for a meeting to discuss the issue of weaning the machine, it is equivalent to saying that the values ​​detected by the test are very good.

The next thing to do is, Xie Wanying continued to add: "Gradually reduce the flow rate of the patient to one-half, and do the above examination with transesophageal echocardiography in the middle. Full flow."

   It turns out that this is the case, this step of weaning off the machine is really very cautious. All the doctors here are brushing and brushing, and no one thinks that the steps are cumbersome. Medicine is never afraid of cumbersome links. The more cumbersome it is, the more careful research is in place, and the more it seems that things are under the control of doctors.

  When Mr. Zhang picked up the steel notebook, his thick eyebrows and big eyes glanced at the uninvited guests at the meeting with displeasure.

   Said that the Xia acting director of the ICU of the National Association of China was so shameless that he came to the meeting every day and forget it. Why, the people from company m who I met only once yesterday came to listen to their meeting.

  Can Mai Hui, a **** who speaks bad Chinese, really understand Teacher Xie's lectures? It turned out that they actually brought an on-site interpreter to help him translate simultaneously, which was absolutely amazing.

  Zhang Huayao's eyebrows were almost wrinkled into two towering mountains.

  The thick-skinned person must have pretended not to see his big brother's expression, and continued to listen to the class with other doctors present.

  Mai Hui has never heard of the plan Xie mentioned, and it is a plan for the future.

   "When the flow rate is reduced to twelve to fifteen and the vis index is less than ten, carry out the capacity load test."

  vis index is the score of vasoactive drugs and inotropic drugs. It is calculated by a complicated formula, which is the sum of various drugs multiplied by the dose. From the overview of this simple formula, it can be inferred that the lower the vis index is or even equal to zero, the best, which is equivalent to not giving the patient these drugs to support the patient's blood pressure.

   Judging the patient's heart under such a premise tends to be able to truly judge the original function of the patient's own heart without assistance, which will help the doctor determine whether the patient can continue to be weaned.

  Volume loading test is to give the patient a certain amount of fluid for a certain period of time, and the purpose is to increase the blood volume to judge the response of the heart. Here is a drop of albumin. The doctor wants to add some difficult questions to the patient before weaning off the machine to further test the patient's heart. At this time, the cardiac function indicators mentioned before must be checked again with transesophageal echocardiography.

  Finally, use dobutamine for a few hours before observing the heart function. If the heart values ​​remain stable, you can stop the machine for testing, and it is safe to enter the formal weaning process.
