The next day, the patient underwent transesophageal echocardiography.
After the examination, a group of doctors held a meeting to discuss the results of the various examinations, and the atmosphere became lively again.
Since everyone was not familiar with this machine as it was their first time to use it, Director Wang, who was presiding over the meeting, slammed the table and said, "Teacher Xie, tell me more about your ideas."
In fact, Director Wang already knew her identity, but the big guys in Lin** all had a bit of the humorous style of Big Boss Zhang. They were used to teasing her as a teacher and it became a catchphrase. It would probably be difficult to change it in a short time.
Seeing that Boss Zhang, who was sitting in the main seat at the conference table, was also shaking his head at her, he pointed the pen in his hand and said: Let Teacher Xie speak.
Xie Wanying could only take a deep breath.
Don't listen to the big guys shouting "Thank you, teacher" left and right. The "big guys' students" have their own professional judgment. They don't just listen to her every word but review it with professionalism and are ready to find fault with her at any time.
At this point, he lowered his head and flipped through the notes in his hand, repeatedly reading the patient's recent test values, and analyzed them comprehensively: "The patient's mean arterial pressure has now reached a level greater than 60."
Many people have heard a lot about blood pressure. Even laymen know that high or low blood pressure is not good for patients.

How much do laymen really know about blood pressure? This is a real question.
The medical definition of blood pressure is very complicated and far from what most people think. For example, the most common definition is that medical staff use a sphygmomanometer to measure people's blood pressure and think that is blood pressure.
The systolic and diastolic blood pressure measured by a blood pressure meter is just an indicator of human blood pressure.
The real medical definition of blood pressure refers to the pressure exerted on the blood vessel wall per unit area when blood flows in the blood vessels. The significance of monitoring blood pressure is to observe whether the fluidity of the cardiovascular circulatory system can provide sufficient blood volume for various tissues and organs to maintain normal metabolism of the human body. Therefore, there are many indicators for clinical monitoring of blood pressure, far more than just systolic and diastolic pressure.
Different blood pressure monitoring indicators are used in various clinical needs to help doctors judge the patient's condition.
The mean arterial pressure mentioned by Xie is one of the blood pressure monitoring indicators. It is not complicated to calculate. Clinicians usually calculate it verbally as diastolic pressure plus one-third of pulse pressure difference.
This is not used for normal blood pressure monitoring. Doctors use it in special situations like today. The purpose is to use it to observe and judge the perfusion of important organs in patients in a simple and easy-to-understand way. This is because various research results show that if the mean arterial pressure is low, the brain tissue, kidney tissue and other important organs of the body will not be effectively perfused, which will lead to the death of the patient, and doctors need to take necessary measures.
What is the lower limit of this indicator? The lowest should not be less than 55. Normal people have a level of more than 70. Considering that the patient is a critically ill patient in the process of recovery, a level greater than 60 is considered a pass.
It seems that the number of patients is quite good now.
The doctors who were listening were very quiet, and none of them showed any expression easily.
It is not enough for a clinician to draw a conclusion based on just one indicator. To obtain the most authentic and reliable answers to matters involving human life, clinical doctors, like detectives solving cases, must find more evidence to prove their speculations, the more the better.
