    During the blood collection process, nurses will often come 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 blood donor's palm and the blood donor will be asked to squeeze the arm muscles to 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 me? I am obviously heavier than you."

    ?????????????????????????????????? Children who are not doctors¡¯ families do not know everything. It is true that they are not students of medicine, how can they have a thorough understanding of medicine.

    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 strength before coming to donate 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, blood volume accounts for 7 to 8% of body weight.  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 constrict and blood flow slows down.  Like Ding Lulu, her nervousness never disappeared. After asking, she asked the nurse: "Are you sure how much blood you have collected from me? I only donated three hundred, don't you want to collect more from me?"

    The nurse was very 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 center of the blood station is more afraid of collecting too much or too little blood than you are. It will use advanced equipment to measure the amount of blood collected in a timely manner.  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, it 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 get more rest when she returned.  It is impossible to take a break for the time being.  My eldest cousin is going to have a CT scan in the morning. If it¡¯s quick, the results may be available in the afternoon.  Thinking this way, Xie Wanying collected her 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 fighting for Xiao Shugang.

    At the same time, in the emergency department, it was normal to work on Saturday morning.  Zhang Huayao arrived at the emergency department a little before 8 a.m.  When I came to the nurse station, I heard the night shift nurse reporting gossip to the head nurse: "Dr. Cao Yong from the National Association of Chinese Medicine came last night."

    "When? What did Dr. Cao come to do?" the head nurse asked in surprise.

    "He's here to care about Dr. Shen's patients." After the nurse said this, she saw Zhang Huayao arrived and shut up.

    "Director Zhang." The head nurse turned to greet Zhang Huayao and saw the unfathomable look 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 Xie himself inform Cao Yong to come?  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 here.

    The smart classmate Xie couldn¡¯t hide it from Cao Yong, which was the expected result, so didn¡¯t he say he had 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.  (Remember the website address: www.hlnovel.com
