Mean arterial pressure is affected by factors such as medications. If medication is used to increase mean arterial pressure, it is a false positive and meaningless. This corresponds to what Mr. Xie said before that drug testing should be conducted cautiously before weaning off the machine.
How to do the specific operation has actually already started.
Did it?
Director Wang and others at the scene were shocked. It seemed that Student Xie had not mentioned any special medicine to be given to the patient before. Let’s talk about one more issue. The significance of mean arterial pressure monitoring: Human perfusion is closely related to the cardiac output of the heart. Cardiac output can be measured using pio technology. If there is no pio technology, transesophageal ultrasound can be used.
Take an echocardiogram test.
Xie Wanying said: "What we just measured was the heart condition under full flow support of the membrane lung. It mainly measured the left heart ejection fraction and the function and capacity of the right ventricle."
Since doctors are now meeting together to discuss the issue of weaning off 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 patient's flow to half, and use transesophageal echocardiography to do the above examinations. Once the left and right ventricles are found to be dilated or the blood pressure drops, immediately
Restore to full traffic. "It turns out that this step of withdrawing the aircraft is really out of caution. All the doctors present here were writing under their pens, and no one thought the steps were cumbersome. Medicine is never afraid of complicated procedures. The more complicated it is, the more it means careful study.
If the research is done properly, it becomes more and more obvious that it is a good thing that things are under the control of doctors.
When Mr. Zhang picked up his pen notebook, he glanced at the uninvited guests at the meeting with displeased eyes.
He said that Director Xia of the National Association for U was so shameless that he just came here every day. Why, people from Si who had only met once yesterday came to listen to their meeting.
Can the foreigner Mai Hui, who speaks poor Chinese, really understand Teacher Xie's lectures? It turned out that they actually brought an on-site translator to help him translate simultaneously, which was absolutely amazing.
Zhang Huayao's eyebrows were almost wrinkled into two big mountains.
The shameless person must have pretended not to see his bossy expression, and stretched his neck with the other doctors present to continue listening to the lecture.
Mai Huizhen had never heard of the plan that classmate Xie mentioned. 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. It is calculated by a complicated formula and is the multiplication of various drugs. In doses it adds up. It can be inferred from this simple formula overview 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. Under such a premise, judging the patient's heart will tend to be able to truly judge the original function of the patient's own heart without assistance, which will help the doctor judge whether the patient can continue to be weaned.
The volume load test is to inject albumin into the patient and finish it 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 test the patient before weaning him from the machine.
Here we will use transesophageal echocardiography to check the cardiac function indicators mentioned before. Finally, use dobutamine for a few hours and then observe the heart function. If the heart function always maintains good stability, the machine can be weaned. .
