During the blood collection process, the nurse will often come over to check whether the blood flow is smooth during the blood collection process and whether the blood donor is feeling unwell. If the blood flow is too slow, a small ball will be placed in the palm of the blood donor's hand and asked to squeeze it.
Squeezing your arm muscles will make the blood flow faster.
The nurse put a small ball in Ding Lulu's hand and pinched it.
Xie Wanying doesn’t need to.
Ding Lulu turned around and asked Xie Wanying: "Did you take any medicine before coming here? Why does your blood flow faster than mine? I am obviously heavier than you."
Therefore, it is not said that children from doctors' families know everything. It is true that they are not studying medicine, so how can they understand medicine thoroughly?
Some people have fast blood flow, and some people have slow blood flow, which is related to 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 and increase blood volume to speed up blood donation.
Xie Wanying did not deny that she drank some water to replenish her energy before donating blood. Furthermore, for people of the same weight, thin people have higher blood volume than fat people. This is because regardless of fatness or thinness, the blood volume of a person is a percentage of body weight.
7 to 8. Ding Lulu is slightly overweight, but on the fat side, and has no blood volume advantage. Not to mention that for a person who exercises regularly, the blood vessels themselves are relatively thick, and the blood flow rate will naturally be faster due to thick blood vessels.
Last but not least, the blood donor's mood will affect the blood flow rate. Once a person is nervous, blood vessels will constrict, and the blood flow will slow down. Like Ding Lulu, the nervousness never goes away. After asking, she asked the nurse: "Are you sure how much blood you collected from me?"
Blood? I only donate three hundred, don't you want to take more from me?"
The nurse was helpless when she received this 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 that you can read by yourself."
The blood station center is more afraid of collecting too much or too little blood than you are. It will use advanced equipment to measure the blood collection volume in time. The blood collection scale will shake the collected blood and the anticoagulant in the blood bag. When the blood collection volume reaches
The set target value will sound.
About ten and five minutes later, Xie Wanying finished donating blood and ended early. The nurse gave her a bottle of milk to supplement her nutrition and told her to rest more after she returned. It was impossible to rest for the time being. Her eldest cousin was going to do a CT scan in the morning, so if she could do it soon,
, the results may be available in the afternoon. Thinking of this, Xie Wanying collected the registered blood donation certificate and left in a hurry.
Ding Lulu looked at her walking away, curled her lips, and decided to lie here comfortably for a while after donating blood. Unlike Xie Wanying, she had no intention of risking her life for Xiao Shugang.
At the same time, the emergency department went to work as usual on Saturday morning. Zhang Huayao arrived at the emergency department a little before eight in the morning. When he came to the nurse station, he heard the night shift nurse reporting gossip to the head nurse last night: "Cao Yong from the National Association last night
The doctor is here."
"When? What is Dr. Cao here for?" the head nurse asked in surprise.
"He's here to take care of Dr. Shen's patients." After the nurse said this, she saw Zhang Huayao arrived and closed her mouth.
"Director Zhang." The head nurse turned to greet Zhang Huayao and saw the unfathomable expression on Zhang Huayao's face after listening to their conversation.
Zhang Huayao was thinking: Cao Yong discovered that he was in their country so quickly. Did classmate Xie notify Cao Yong himself? Probably not.
Dr. Yao, who worked the night shift, came over and explained to him that Cao Yong would not let anyone 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 there was a good show to watch?
Zhang Huayao raised his eyebrows, turned around and took Dr. Yao and the others to inspect the patients.
A group of doctors walked to Xiao Shugang's bedside.
