During the blood collection process, nurses will often come to inspect whether the blood flow is smooth during the blood collection process and whether the blood donor is feeling unwell. If the blood flow speed is too slow, a small ball will be placed in the palm of the blood donor, so that he can pinch the muscles on his arm and force it will make the blood flow faster.
Ding Lulu was squeezed by a small ball in her hand.
Xie Wanying doesn't need it.
Ding Lulu turned her head and asked Xie Wanying: "Did you take any medicine before you come? Why are your blood flowing faster than me? I obviously weigh more than you."
So it is said that children from doctors who know everything. Of course, they are not studying medicine, so how can they understand medicine thoroughly?
Some people have fast blood flow, while others have slow blood flow, which is related to everyone's blood condition. The blood viscosity and blood volume will all affect the speed of blood donation.
Drinking some water before donating blood can effectively reduce blood viscosity and increase blood volume and speed up blood donation.
Xie Wanying does not deny that she drank some water before donating blood to replenish her physical strength. In addition, people of the same weight, thinner people have higher blood volume than those of fat people. This is because no matter whether they are fat or thin, their blood volume accounts for 7 to 8% of their weight. Ding Lulu is slightly heavier, but she is a little fat and has no blood volume advantage. Not to mention a person who exercises regularly, the blood vessels themselves are thicker, and the blood vessels are thicker, and the blood flow rate is naturally fast.
Last point, the blood donor's emotions will affect the blood flow rate. Once a person is nervous, the blood vessels contract and the blood flow will slow down. Like Ding Lulu, the tension never disappeared. After asking her, she asked the nurse: "Are you sure how much blood you have collected from me? I only donated three hundred, don't you pick me more?"
The nurse was extremely helpless when she received this question. She pointed to the blood collection handful that was always placed under the blood bag during the blood collection process, and said, "There are numbers here and you can see it yourself."
The center of the blood station is more afraid of collecting more or less of your blood than you. It will use advanced equipment to collect blood, which means to measure the blood collection volume in time. The blood collection means to shake the collected blood and the anticoagulant in the blood bag. When the blood collection volume reaches the set target value, it will ring.
About ten minutes later, Xie Wanying finished giving her blood and ended early. The nurse brought her a bottle of milk to supplement her nutrition and told her to rest more after she went back. It is unlikely that she would take a rest for the time being. My cousin would go for a CT examination in the morning, and if it was fast, the result might be produced in the afternoon. Thinking of this, Xie Wanying collected her registered blood donation certificate and hurried to leave.
Looking at Ding Lulu who had left, she curled her lips and decided to give her blood and lay comfortably here for a while before talking. She didn't look like Xie Wanying, and she had never planned to fight for Xiao Shugang.
At the same time, the emergency department went to work normally on Saturday morning. Zhang Huayao arrived at the emergency department just before 8 o'clock in the morning. He came to the nurse station and heard the nurse who was on night shift last night reported to the head nurse: "Dr. Cao Yong from the National Association came last night."
"When? What did Dr. Cao come to do?" the head nurse asked in surprise.
"He comes to care about Dr. Shen's patients." After the nurse said this, she saw Zhang Huayao arrive and shut up.
"Director Zhang." The head nurse turned around and greeted Zhang Huayao, and saw the mysterious face on Zhang Huayao after listening to their conversation.
Zhang Huayao thought to himself: Cao Yong discovered that he was in their country so quickly. Did classmate Xie notify Cao Yong by himself? It shouldn't be.
Dr. Yao, who was working in the night shift, came over and told him that Cao Yong would not let someone say that he had been there.
The smart student Xie cannot hide it from Cao Yong, which is the result of his imagination, so didn’t he say there is a good show?
Zhang Huayao raised his eyebrows, turned around and took Dr. Yao and the others to patrol the patients.
