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 Mr. Xie hadn't said that he would give the patient any special medicine before. There's one more question to talk about. Significance of mean arterial pressure monitoring Human perfusion is closely related to cardiac output of the heart. Cardiac output can be measured with picco technique, without picco technique, transesophageal ultrasonography can be used
Echocardiography to measure.
Xie Wanying said: "We just measured the condition of the heart 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."
Now that the doctors are meeting to discuss the issue of weaning the machine, it is equivalent to saying that the values detected 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 then do the above examination with transesophageal echocardiography in the middle.
back to full flow. "It turns out that this is the case. The steps of weaning off the machine are really very cautious. All the doctors here are brushing their heads, and no one thinks that the steps are cumbersome. Medicine is never afraid of cumbersome links. The more cumbersome, the more careful study
If the research is in place, the more it seems that it is a good thing 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 acting director Xia 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 M Company, whom I only met once yesterday, came to listen to their meeting.
Can Mai Hui, a foreigner 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 big 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 had never heard of the plan that Xie mentioned, and it was a plan for the future.
"When the flow rate drops to 12 to 15 and the vis index is less than 10, perform a volume load test." The vis index is the score of vasoactive drugs and inotropic drugs. Add up in doses. From this simple formula overview, it can be inferred that the higher the vis index
When it is low or even equal to zero, it is 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.
.
The volume loading test is to give the patient a drop of albumin and finish the drop within a certain period of time. The purpose is to increase the blood volume to judge the response of the heart. It is to add some difficult questions to the patient before weaning the machine.
Here, transesophageal echocardiography should be used to check the cardiac function indicators mentioned before. Finally, use dobutamine for a few hours before observing the heart function. If the heart remains stable in all aspects, the machine can be weaned off.
