During the blood collection process, the nurse will often come to check whether the blood flow is smooth and whether the donor is feeling unwell. If the blood flow is too slow, a small ball will be placed in the palm of the donor's hand, asking him to squeeze his arm muscles to make the blood flow faster.
The nurse stuffed a small ball into Ding Lulu's hand.
Xie Wanying doesn't need it.
Ding Lulu turned around and questioned Xie Wanying: "Did you take any medicine before you came? Why is your blood flowing faster than mine? I obviously weigh more than you."
So it’s not that children of doctors know everything. They are certainly not studying medicine, so how can they have a thorough understanding of medicine?
Some people have fast blood flow, while others have slow blood flow. It has something to do with each person's blood condition. Blood viscosity and blood volume will affect the speed of blood donation.
Drinking some water before donating blood can effectively reduce blood viscosity, increase blood volume and speed up blood donation.
Xie Wanying did not deny that she drank some water to replenish her energy before donating blood. In addition, for people of the same weight, thin people have higher blood volume than fat people, because no matter fat or thin, the blood volume of a person accounts for 7 to 8 percent of body weight. Ding Lulu is slightly heavier, but she is fat, so she has no blood volume advantage. Not to mention that a person who exercises regularly has thicker blood vessels, and thicker blood vessels naturally have faster blood flow.
Finally, the emotions of the blood donors will affect the blood flow rate. Once a person is nervous, the blood vessels will contract and the blood flow will slow down. Like Ding Lulu, the nervousness has never disappeared. After the question, she questioned the nurse: "Are you sure how much blood you took from me? I only donated 300, don't take more from me?"
...
...
The nurse was extremely helpless when she received her question. She pointed to the blood collection scale that was always placed under the blood bag during the blood collection process and said, "There are numbers here and you can see them yourself."
The blood center is more afraid of collecting too much or too little blood from you than you are, so it will use advanced equipment, the blood collection scale, to measure the amount of blood collected in time. The blood collection scale will shake the collected blood and the anticoagulant in the blood bag, and it will sound when the blood collection volume reaches the set target value.
About ten and a half minutes later, Xie Wanying finished donating blood and ended early. The nurse brought her a bottle of milk to supplement her nutrition and told her to rest more after returning. Resting is not possible for the time being. My cousin is going to have a CT scan in the morning. If things go well, the results may be available in the afternoon. Thinking of this, Xie Wanying put away the registered blood donation certificate and left in a hurry.
Ding Lulu looked at her leaving, curled her lips, and decided to lie here comfortably for a while after donating blood. Unlike Xie Wanying, she had never planned to risk her life for Xiao Shugang.
Meanwhile, the emergency department was working as normal on Saturday morning. Zhang Huayao arrived at the emergency department a quarter before eight in the morning. When he arrived at the nurses' station, he heard the nurse on night duty last night reporting a rumor to the head nurse: "Dr. Cao Yong from the National Association came last night."
"When? What is Doctor Cao here for?" the head nurse asked in surprise.
"He's here to check on Dr. Shen's patients." After the nurse said this, she saw Zhang Huayao coming and shut up.
"Director Zhang." The head nurse turned around and greeted Zhang Huayao, and saw the mysterious look on Zhang Huayao's face after he listened to their conversation.
Zhang Huayao was thinking: How did Cao Yong find out that someone was in their country so quickly? Did Xie notify Cao Yong to come? Probably not.
Doctor Yao, who was on the night shift, came over and explained to him that Cao Yong didn't want anyone to know that he had been there.
It was expected that clever student Xie could not hide the secret from Cao Yong, so didn’t he say that there would be something interesting to watch?
Zhang Huayao raised his eyebrows, turned around and took Dr. Yao and others to check on the patients.
A group of doctors walked to Xiao Shugang's bedside.
