Chapter 1592 【1592】Desperate
During the blood collection process, nurses will come and go to check whether the blood flow is smooth during the blood collection process and whether the blood donors are feeling unwell. If the blood flow rate is too slow, a small ball will be placed in the palm of the blood donor, and the donor will be asked to pinch the arm muscles to make the blood flow faster.
Ding Lulu was stuffed with a small ball by the nurse.
Xie Wanying doesn't need it.
Ding Lulu turned her head and asked Xie Wanying: "Did you take any medicine before you came here? Why is your blood flow faster than mine? I am obviously heavier than you."
So it is not a child of a doctor's family who understands everything. It is true that they are not medical students, so how can they have a thorough understanding of medicine.
Some people have fast blood flow, while others have slow blood flow, which is related to each person's blood condition. 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 to speed up blood donation.
Xie Wanying did not deny that she drank some water to replenish her strength before donating blood. Furthermore, for people of the same weight, thin people have higher blood volume than fat people. This is because regardless of fat or thin, people's blood volume accounts for 7 to 8% of their body weight. Ding Lulu is slightly heavier, but she is on the fat side and has no advantage in blood volume. Not to mention a person who exercises regularly, the blood vessels themselves are relatively thick, and the blood flow in thick blood vessels is naturally fast.
Finally, the emotion of the blood donor can affect the blood flow rate. Once a person is tense, the blood vessels constrict and the blood flow slows down. Like Ding Lulu, the tension never disappeared. After asking, she asked the nurse again: "Are you sure how much blood you have collected? I only donate three hundred. Don't you take more of me?"
The nurse was very 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, "Here are the numbers for you to read for yourself."
The blood bank center is more afraid of taking too much or less blood than you, and will use advanced equipment 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 when the blood collection volume reaches the set target value, it will sound.
About ten to five 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 home. It is impossible to want to rest for the time being. My cousin is going to have a CT scan in the morning. If we hurry up, the results may be available in the afternoon. Thinking this way, Xie Wanying collected the registered blood donation certificate and hurried to leave.
Watching her go away, Ding Lulu curled her lips, and decided to lie here comfortably for a while after donating blood. Unlike Xie Wanying, she had no intention of working hard for Xiao Shugang.
At the same time, in the emergency department, it is normal to go to work on Saturday morning. Zhang Huayao arrived at the emergency department a quarter before eight o'clock in the morning. When I came to the nurse station, I heard that the nurse on night shift reported the gossip to the head nurse: "Dr. Cao Yong from the National Association of China came last night."
"When? What is Dr. Cao here for?" the head nurse asked in surprise.
"He came to care about Dr. Shen's patients." After the nurse finished speaking, she shut her mouth when she saw Zhang Huayao had arrived.
"Director Zhang." The head nurse turned to greet Zhang Huayao, seeing the unfathomable expression on Zhang Huayao's face after listening to their conversation.
Zhang Huayao thought in his heart: Cao Yong found out that he was in their country so quickly. Did classmate Xie inform Cao Yong to come over? Probably not.
Dr. Yao, who was on the night shift, came over and explained to him that Cao Yong would not let people say that he had been there.
The smart classmate Xie couldn't hide it from Cao Yong, which was the expected result, so didn't he say that there is a good show to watch?
Zhang Huayao raised his eyebrows, turned around and took Dr. Yao and the others to check on the patients.
A group of doctors came to Xiao Shugang's bedside.
