We need to use past cases as a reference to make decisions. The current speed measurement must not be vague and impressionistic as Pan said. It is just a rough idea of whether the upstream speed is fast or slow. A more accurate value must be measured.
"You don't need to say anything." Sun Yubo wanted to hold his head with both hands. He must say that his student Xie classmate Niu Honghong.
To put it this way, it is calculated by looking at the monitor screen of the ventriculoscope while looking at the electrocardiogram. The two are combined.
The one who could figure it out was a god. Sun Yubo was completely convinced.
Classmate Geng Yongzhe turned his head obediently, his eyes running back and forth on the two machine screens.
Can't admit defeat. Look at Beidu Song Mao looking at the three of them, the arrogance in his eyes says: I knew the three of them were so bad.
There was no way, they couldn't get into the rhythm when they first arrived. Wei Shangquan was so angry that he was dying.
Why can Dr. Xie do it, and why can’t you? And you still claim to be Dr. Xie’s classmate with confidence? Song Xuelin doesn’t pity the three of them.
"I understand." Classmate Pan Shihua raised his head again and said, "The downward flow velocity during systole is about 4.5 centimeters per second, and the upward flow velocity during diastole is about five centimeters per second."
Classmate Pan figured it out. Wei Shangquan and Geng Yongzhe immediately turned around and thought: There is hope.
Did this guy really figure it out? The second-year general foreign students remembered the rumors that there were other strange people in Xie’s class. Among them, there was a special one named Pan. He should be this classmate. The eyes of several people were on Pan
Look at the classmates’ faces a few times.
If the junior brother could calculate it, Huang Zhilei didn't know how to put it on his face. The main reason was that he couldn't decide whether the junior brother's calculation was right or wrong.
"Wrong." Song Xuelin spat out lazily.
Wrong? True or false? At this time, there are really many people like Huang Zhilei who can’t decide who is right.
"If you don't believe it, ask Dr. Xie if it's true?" Song Xuelin said.
"This -" Xie Wanying said, "Don't rush to measure the flow rate, just measure the flow rate."
Student Wei and the others recognized it immediately, and she was trying to comfort them.
All I can say is that Mr. Xie is really awesome.
It seems to be difficult to measure the speed directly, but I wonder if it will be easier to measure the flow rate. Measuring the flow rate can measure the flow rate of a cardiac cycle, including the systolic period and the diastolic period.
"How do you judge whether his calculation is wrong?" Sun Yubo couldn't help but curiously asked if someone had actually calculated it.
"What he said are normal values for healthy people, is that good?" Song Xuelin continued to say in a lazy tone.
Others could tell that this talented man from Beidu really had no intention of leaving any face to the other party.
Although everyone in the hospital knew that Song Xuelin was very arrogant, they really didn't expect that he would act tit-for-tat and want to tear each other's face apart.
It seemed that classmate Pan had unintentionally offended the talented man from Beidu. This was the only thought that flashed through everyone's mind at that moment.
Classmate Pan's gentle face continued to remain calm. After a while, he said like an invincible Xiao Qiang: "For downward flow, one cardiac cycle is about 0.7 ml, and for upward flow, it is about 0.45 ml. I admit that I calculated it wrong before.
The deviation is relatively large.”
Is Mr. Pan’s calculation correct this time?
Wei Shangquan hurriedly scanned the expressions of everyone present to find the answer. In fact, only those few people could do the calculation.
"These two numbers are pretty much what I thought." Xie Wanying said.
